Through field observation and lab analysis, 13 agronomic traits, including plant height and effective branching number per plant, etc., of 207 faba bean (Vicia faba L.) germplasms saved in Crop Middle-term Genebank of Hubei Province were evaluated, moreover, the identification on the disease resistance and the quality was carried out on parts of germplasm resources. The results showed that the faba beangermplasm resources in Hubei Province were abundant, the variation range of agronomic traits like the growth period, plant height and 100-bean weight, etc., was great, and the range of choice was wide. In the aspect of quality, there were 9 germplasms withthe content of crude protein higher than 30%, and the variation range of amylose content in total starch was large, which provided excellent sources of parents for breedinq hi.qh-quality faba bean varieties in Hubei Province. 展开更多

This study analyzed the tartary buckwheat recorded in the books Catalogue of Crop Germplasm Resources in Shanxi Province and Catalogue of Chinese Buckwheat Germplasm Resources by Excel 2003 and DPS 7.5 from the aspects of distribution areas,main agronomic traits and nutritional components,so as to lay a foundation for the selection of excellent buckwheat germplasm resources and improvement of buckwheat varieties.The results showed that different buckwheat varieties vary in plant height,node number of the main stem,grain weight per plant,grain weight per plant and kilo-grain weight.Compared with the national average values,buckwheat in Shanxi is higher in protein and fat,but lower in vitamin E and vitamin PP;it is rich in Ca,Mg,Cu,P,Se,Fe,Mn and Zn;and it contains 18 amino acids with the content of glutamic acid being the highest and the content of tryptophane being the lowest.After analyzing and classifying the tartary buckwheat germplasm resources recorded in Catalogue of Grop Germplasm Resources in Shanxi Province and Catalogue of Chinese Buckwheat Germplasm Resources,breeders could breed new varieties with high yield and quality and strong stress resistance by crossbreeding with these germplasm resources. 展开更多

For the last two decades the world has undergone a population explosion which has been accompanied by a speeding up of urbanization and land use for industrial and agricultural products. These involve a vast increase in the discharge of pollutants into very different receiving water bodies, and have had adverse effects on the various components of the environment. For a long time, human has concerned a little of the natural environment. It is obvious that this variation in surface temperature of the earth increases the level of sea due to snowmelt. So climate change is manifested by many phenomena: floods, droughts, fires, tornadoes, cyclones, earthquakes, volcanic eruptions, diseases etc.. The statement today is dramatic. Entire regions were devastated and many rivers and lakes have become polluted around the world. Pollution has it nature which is hard to be absorbed. Where did the different pollutants come from? What are the risks to the aquatic environment? To prevent and combat the general decline of these ecosystems, it is important to distinguish and determine the effects of different sources of pollution and any changes that may suffer the physical environment. The climate depends primarily on changes in earth orbit parameters, which affect the solar radiation received by the earth surface. Therefore, human participates strongly to these changes, for example, pollution is the main reason to argue the greenhouse effect, an increase of anthropogenic carbon dioxide (CO2) into the atmosphere, which promotes global warming to the planet. These modifications are already applied in order to ensure durable development in water resources by controlling discharges into streams to preserve water resources for future generations and to ensure reconciliation between man-climate and environment. 展开更多

A collecting mission was carried out in south-west Romania in October 2013 with the aims: (1) to collect autochthonous crop genetic resources which still present in the south-west of Romania; (2) to assess the presence of on farm of plant genetic resources; (3) to determine the species and the amount of genetic diversity still cultivated and (4) to obtain information from germplasm owners to be used to evaluate the feasibility of an on farm conservation program. Out of 24 explored towns, in 8, landraces were grown and in all, instances seeds could be obtained. Fifty-three accessions from different crop species were collected in 17 sites, belonging to 10 botanical families, of which solanaceae was the most represented (32%), followed by fabaceae (17%), cueurbitaceae (11%) and alliaceae and brassicaceae (9%). As expected, vegetable crops were the most collected, reaching a value as 58.5%, spices 20.8%, while pulses 15.1% and cereals 5.7% of the total. This collecting mission showed that in internal areas of Romania, germplasm of old landraces of many vegetable and crop species still survive, and indicated the urgency to continue also in other agricultural districts of Romania. 展开更多

The research topic is the one of public finance company whose core business is focused to support investment projects to overcome enterprises technological and structural gap. The research question is: If and how a public finance company is able to create and favor value creation processes sustainability for agro-food enterprises, highlighting the positive emerging externalities for different categories of stakeholders. They have results with particular evidences allow comparisons between the private investments and the support of institutional public investors. In such perspective, the mode of disbursement of soft loans and investment operations made by a public financing company will be examined. The methodological approach used, following a deductive-inductive perspective, is based on the ease study. Such technique able to formulate theories about a little known phenomena in their context, allows the study of recent events on which the researcher has little control. To this, a qualitative analysis on both primary and secondary data adds. From data analysis, it resulted that the Institute of Agribusiness Development (ISA) initiatives facilitated, just for example, the technological innovation of production department and consequent production capacity, the acquisition of production assets for row material processing and optimization of internal logistics, through an innovative automated warehouse. As a result, the case study finds sustainability at multiple levels reached by the activities promoted by ISA and the subsequent co-creation of value for stakeholders involved, small agro-food businesses innovation, and/or internationalization processes. As long as practical implications are concerned, such highlight the importance and the need for public and private institutions in their effort to continue to invest in projects to support the economy of the country. The originality of the paper lies in the proposed interpretation of more integrative paradigms (viable system approach, sustainability, and, value creation), analyzing a financial institution for the development of the Italian food industry. At the same time, authors stress the research limit that is the analysis of the input of only one organization and consequent limited data in quantity and time span. 展开更多

As a consequence, million hectares of land exchanged hands. The ways the transfers happened combined with their geographic concentration in Sub-Saharian Africa, have earned the phenomenon the name of "land grab". The agricultural sector considered a "sunset industry" when commodities prices were declining, is now attractive to financial investors. These foreign investments may be good as they may improve agricultural productivity or instead bad as they may benefit only financial investors. Some results in terms of environmental and local communities' worsening conditions have already emerged. This paper aims to investigate what drives the big size transfers of land, to empirically estimate their effects in terms of local employment and to assess the environmental effects produced by the rapid transformation in the use of vast amount of land in terms of CO2 emissions. It is also proposed to use the estimation in terms of local employment impact as a way of distinguishing between foreign direct investment and land grabbing. 展开更多
