Characterization of high-yield performance as affected by genotype and environment in rice

We characterized yield-relevant characters and their variations over genotypes and environments （locations and years） by examining two rice varieties （9746 and Jinfeng） with high yield potential. 9746 and Jinfeng were planted in two locations of Shanghai, China, during 2005 and 2006. The results show that there was a large variation in grain yield between locations and years. The realization of high yield potential for the two types of rice was closely related to the improved sink size, such as more panicles per square meter or grains per panicle. Stem and leaf biomasses were mainly accumulated from tillering stage to heading stage, and showed slow decline during grain filling. Meanwhile, some photosynthetic characters including net photosynthesis rate （Pn）, leaf area index （LAI）, specific leaf area （SLA）, fluorescence parameter （maximum quantum yield ofPSll, Fv/Fm）, chlorophyll content （expressed as SPAD value）, as well as nutrient （N, P, K） uptake were also measured to determine their variations over genotypes and environments and their relationships with grain yield. Although there were significant differences between years or locations for most measurements, SLA at tillering and heading stages, Fv/Fm and LAI at heading stage, stem biomass at heading and maturity stages, and leaf nitrogen concentration at tillering and heading stages remained little changed, indicating their pos- sible applications as selectable characters in breeding programs. It was also found that stem nitrogen accumulation at tillering stage is one of the most important and stable traits for high yield formation.

Web content analysis of agricultural cooperatives located in Turkey

After the appearance of the globalization process post of 1980＇s, world has becaming a big village, that had been brought many important outcomes related with cooperatives which are aimed to emit the capital to the base. These conditions have been forced the movement to adopt themselves to this process vitally. As of year 2007, there are 26 several types of cooperatives with 90.086 unit cooperatives which have total number of 8,561.618 partners that are all dependent to Turkish cooperative association as well as Ministry of Industry and Commerce. In this study, the web sites of Turkish agricultural cooperatives were examined in terms of their contents. Also, it is tried to find out the sufficiency level of their electronic marketing activities. Within the context of this study, web sites of 5 agricultural cooperatives are examined in terms of their design.

Community participation in the management of wetland nature reserve:a case study of Nanjishan Nature Reserve, Jiangxi, China

In recent years, more and more conflicts have emerged in the management of nature reserves, of which themain problem is that how to carry out the campaign of conservation along with the promotion of development of localeconomics. To resolve the actual problem in Nanjishan National Wetland Nature Reserve and explore the idiographicmethod of the management of the wetland reserve, some studying methods including face-to-face interviews, informaldiscussion with local leaders and officials, group discussion with local fishers, questionnaire, and job of the conversationstation have been carried out. The results show that the education level of the local people is low; only 5% of the localpeople have an opportunity to the junior college; the main income of the local people is fishing, which accounts for 70%more or less; and the income is coming down year by year because of the unreasonable way of fishing. To cope with theproblems, some reformative way of management and the development of the reserve are introduced, such as establishingan NOG that constitutes of local fishermen to achieve the goal of community co-management, developing Bed andBreakfast and so on. Through practice of the management of the participation of the local people, we draw the conclusionthat the local people have a great desire to improve their life level, and to make the co-management of the reserve easy,it is important for the managers to play the role of pilot including engrafting the new ideas, giving some subsidy toencourage the local people to take part in the management. In addition, making local people perceive value of the reserveand the close relation between reserve conservation and the promotion of level of their life. On this basis, they incline totake part in the management of the reserve.

Tripartition of Arbitrary Single-Qubit Information via a Class of Asymmetric Four-Qubit W State

A four-party scheme is put forward for a sender to partition arbitrary single-qubit information among three receivers by utilizing a class of asymmetric four-qubit W state as quantum channels. In the scheme the sender＇s quantum information can be recovered by the three receivers if and only if they collaborate together. Specifically, they collaborate to perform first two different 2-qubit collective unitary operations and then a single-qubit unitary operation. The scheme is symmetric and （3, 3）-threshold with regard to the reconstruction, for any receiver can be assigned to conclusively recover the quantum information with the other two＇s assistances.

Internationalization in Egypt： Risks and Opportunities

Despite of Egypt is facing a period of political uncertainty, some Italian firms have a great interest in operating business in Egypt. Egypt has bilateral agreements with Italy since 2007. As a result of this relation, Italy has become a strategic partner for Egypt, gaining a growing importance in the Middle East. Egypt is, also, an important trading partner for the Italy. Political and economic relationship between Egypt and Italy has increased the interest in analyzing risks and opportunities for Italian firms that would like to operate in Egypt. However studies focused on this topic are still missing. With the aim to fill this gap, this article presents a study based on face to face interviews to some Egyptian senior-executives who manage in Egypt productive centres and representative offices of Italian finns. These interviews led to evidence opportunities and risks that Italian firms have to face operating business in Egypt.

Response of Lettuce to the Coupling Electrical Conductivity and Circulation Rate of the Nutrient Solution in Hydroponics

The coupling effect of nutrient solution EC （electrical conductivity） levels and CR （circulation rate） on the morphology and quality, in hydroponically grown lettuce was assessed. Lettuce was grown at 5 treatments fi＇om High EC ＆ Low CR to Low EC ＆ High CR. The environmental parameters were controlled in a 20 m^2 plant factory during the hydroponic cultivation with the following values： irradiated by blue and red light-emitting diode lighting with PPFD （photosynthetic photon flux density） value of 150 mol·m^-2·s^-1 for 16 hours per day; Temperature was maintained at 22.0 ℃ during the photoperiod and 16.0 ℃ in dark cycle. The results demonstrate that growing lettuce can be adopted using nutrient solution with lower EC levels and higher CR. The results also indicate that the effect of bi-directional coupled EC and CR resulted in expansion of root length but reducing the root biomass. Nitrate content was significantly reduced.

Effects of elevated CO_2 on the photosynthesis and nitrate reductase activity of Pyropia haitanensis(Bangiales,Rhodophyta) grown at different nutrient levels

Pyropia haitanensis, a commercially important species, was cultured at two CO2 concentrations （390× 10^-6 and 700× 10^-6 （parts per million）） and at low and high nutrient levels, to explore the effect of elevated CO2 on the species under nutrient enrichment. Results show that in CO2-enriched thalli, relative growth rate （RGR） was enhanced under nutrient enrichment. Elevated CO2 decreased phycobiliprotein （PB） contents, but increased the contents of soluble carbohydrates. Nutrient enrichment increased the contents of chlorophyll a （Chl a） and PB, while soluble carbohydrate content decreased. CO2 enrichment enhanced the relative maximum electronic transport rate and light saturation point. In nutrient-enriched thalli the activity of nitrate reductase （NRA） increased under elevated CO2. An instantaneous pH change in seawater （from 8.1 to 9.6） resulted in reduction of NRA, and the thalli grown under both elevated CO2 and nutrient enrichment exhibited less pronounced reduction than in algae grown at the ambient CO2. The thermal optima of NRA under elevated CO2 and/or nutrient enrichment shifted to a lower temperature （10-15 ℃） compared to that in ambient conditions （20℃）. We propose that accelerated photosynthesis could result in growth increment. N assimilation remained high in acidified seawater and reflected increased temperature sensitivity in response to elevated CO_2 and eutrophication.

Influences of Agricultural Practices in the Canton Erde-Pala Chad Vegetation

The study, conducted in the Canton Erd6-Pala Chad, aims to i） list the different cultural practices, ii） study their impact on the vegetation and iii） determine the methods of co-management of these cultural practices. The surveys were realized on 50 households in the village and phytosociological plants in corn, millet, cotton and peanuts cultures. The data analysis by statgraphic and Excel and Principal Component Analysis （PCA） showed that maize production （1,200 kg/ha） ranked first at the expense of cotton （640 kg/ha）. They negatively affect climate change （temperature increase （26%）, rain drop （20%）, land reclamation （18%） and flooding （12%））. Surveys of vegetation on three acres cotton fields （76.17%）, millet （81.06%）, corn （80.32%） and groundnut （83.56%） showed that there is no significant difference （P = 0.05） on the specific contribution of wood of different types of farming practices. Adventists species herbacious like Thelepogon elegans （27.84%）, Hyptis spicigera （19.31%）, Teramnus labialis （15.86%） have most important contributions in specific cultures. Methods of crop treatments have a destructive impact on the environment and the loss of biodiversity and the invasion of crops by adventists. Co-management, crop rotation, association of cultures, community forest management, agroforestry and training farmers in the use of inputs will reduce the potential risks of farming practices.

The Importance of Altruistic Empathy and Collaborative Negotiation in Public-Private Partnerships

The motivation in public-private partnerships （PPPs） is to harness the strengths of public and private partners to deliver essential public services. The ability to transfer risk to the private sector in PPP has been one of the reasons why the public sector relies on the private sector to participate in the development of infrastructure projects. In most instances, the public sector also believes that the private sector can fund the project at a lower cost. The private sector on the other hand, believes that they could achieve a strong financial return based on the concessions that the public sector will provide. If the sectors feel altruistic empathy to each other, they will realize that their original goals are not achievable. However, having understood the other sector＇s needs and constraints, collaborative negotiation will yield a set of common goals. There are no commonly agreed frameworks on collaborative negotiation before PPP is formally established. The objective of this paper is to use deductive analysis to develop a conceptual framework for inquiring into the motivations of the public and private sectors during negotiation. This framework will provide insights on the extent of altruistic empathy of both sectors at the onset and how this altruistic empathy frames collaborative negotiation. This paper shows that collaborative negotiation will influence the success of partnerships and altruistic empathy is an important preamble to collaborative negotiation. This paper provides a frame of reference for future study using other research methods for further validation.

The research submitted is based on the approach developed by OECD （Organization Economic Cooperation and Development）. Annual total phosphorus averages formed a classification system. A probability assumption for each water body to reach some given trophic status was taken into account. Probability distribution curves for the average lake phosphorus have been analytically approximated.

FRUIT NUTRITIVE FACTOR NETWORK

As an research example of the widely existing cooperation-competition systems,the authorspresent an empirical investigation on a fruit nutritive factor network.It is described by a node-weightedbipartite graph.The fruit nutritive factors are defined as the nodes,and two nodes are connected by anedge if at least one fruit contains these two nutritive factors.The fruits are defined as the collaborationacts.The node-weight W_(nt),which signifies the 'importance degree' of each actor node,is defined as thecont ent of a nutritive factor in a fruit.The empirical investigation results show some unique features.The node-weight distributions take so-called 'shifted power law' function forms,but the act-weightdistribution takes a normal form.The degree and act-degree distributions show impulsive-spectrumlike forms.These observations may be helpful for the study of fruits.The network description methodproposed in this article may be universal for a kind of cooperation-competition systems.

Can Biochar Protect Labile Organic Matter Against Mineralization in Soil?

Biochar could help to stabilize soil organic （SOM） matter, thus sequestering carbon （C） into the soil. The aim of this work was to determine an easy method i） to estimate the effects of the addition of biochar and nutrients on the organic matter （SOM） mineralization in an artificial soil, proposed by the Organization for Economic Co-operation and Development （OECD）, amended with glucose and ii） to measure the amount of labile organic matter （glucose） that can be sorbed and thus be partially protected in the same soil, amended or not amended with biochar. A factorial experiment was designed to check the effects of three single factors （biochar, nutrients, and glucose） and their interactions on whole SOM mineralization. Soil samples were inoculated with a microbial inoculum and preincubated to ensure that their biological activities were not limited by a small amount of microbial biomass, and then they were incubated in the dark at 21 ~C for 619 d. Periodical measurements of C mineralized to carbon dioxide （CO2） were carried out throughout the 619-d incubation to allow the mineralization of both active and slow organic matter pools. The amount of sorbed glucose was calculated as the difference between the total and remaining amounts of glucose added in a soil extract. Two different models, the Freundlich and Langmuir models, were selected to assess the equilibrium isotherms of glucose sorption. The CO2-C release strongly depended on the presence of nutrients only when no biochar was added to the soil. The mineralization of organic matter in the soil amended with both biochar and glucose was equal to the sum of the mineralization of the two C sources separately. Furthermore, a significant amount of glucose can be sorbed on the biochar-amended soil, suggesting the involvement of physico-chemical mechanisms in labile organic matter protection.
