Comparative Study of Rice Morphogenesis with Different Cultivation Methods

[Objective] The aim of this study was to compare the morphological char- acteristics of rice （Oryza sativa L.） with different cultivation methods and investigate the dynamics of organ growth and development characteristics of different rice culti- vars. [Method] Based on continuous field observation and destructive sampling over a growing season, detailed organ morphological data were obtained including leaf length, node number, plant height, tiller number, leaf angle, leaf area and specific leaf weight, to compare organ morphological differences among 4 rice cultivars of Baidao （indica）, Jinnanfeng （japonica）, 9325 （japonica） and 9915 （japonica） with 3 cultivation methods of field planting in Weigang, pot planting in Weigang, and field planting in Jiangpu. [Result] Maximum leaf length of each node gradually increased at the early growth stage and decreased at the later growth stage, the relationship between maximum leaf length and node position can be described by the equations y=a,,-~ and y=ax＋b; node number, growth duration, leaf length and plant height of pot planting rice in Weigang were smaller than that of the other two field planting meth- ods; the relationship between plant height and sunshine duration, plant height and GDD （growing degree days） can be described by the equation y=ax＋b, 19.23 ℃.d of GDD （≥10 ≥-d） and 8.12 h of sunshine duration were required to increase 1 cm of plant height; plant height, tiller number, and leaf area of Baidao were higher than that of the other 3 laponica rice cultivars, but the specific leaf weight and leaf angle were smaller. [Conclusion] Comparison of morphological characteristic differ- ences among rice cultivars is an important way to select water-saving and drought- tolerant rice varieties. In this study, the experimental results can be integrated into a rice functional-architectural model to simulate rice organ growth dynamics in a three- dimensional space, thereby providing reference for selecting water-saving and drought-tolerant rice cultivars.

Can Emerging Economies Catch-up Sustainably？-An Analysis of BRICS＇ Economic Growth Pattern

The BRICS （Brazil, Russia, India, China and South Africa） and other emerging economies have become a driving global force for the past twenty years. However, their growth patterns are obsolete, impeding the quality and competitiveness of their economic growth, while simultaneously threatening the sustainability of their economic convergence with developed nations. Transforming the domestic growth pattern-the solution to the middle-income trap-has therefore become a key priority for each of these economies. This paper presents a comparative analysis of how to transform the pattern of economic growth in BRICS and achieve sustainable economic convergence with a comparative analysis of the pattern of economic growth and problems among BRICS countries.

China＇s Industrial Transition and Upgrade to Sustainable Growth Model

China＇s transition to sustainable growth model in the coming years depends on the ability of its industrial sector to adapt and innovate. In the llth Five-Year Plan period, China entered the intermediate stage of industrialization and crossed the threshold to become a middle-income country. China＇s current industrial structure, therefore, which is still characteristic of early-stage industrialization, must transition to support intermediate and advanced industrialization. Although resource constraints will pose certain hurdles for this transition, the pressure of these constraints will ultimately serve to catalyze, rather than impede, sustainable industrial growth. Furthermore, industrial transition and upgrade will mean not only changes for the nation＇s industrial structure as a whole but also rethinking the strategic possibilities and direction of industry at the enterprise level. The key to success rests on China＇s ability to improve indigenous development and boost competitive advantage in international markets through the use of new, advanced technologies.

China＇s Economic Slowdown under Supply-Side Perspective

This paper creates an analytical framework for ongoing China＇s economic slowdown and reveals the major.factors affecting potential growth rate. First, proceeding from the factors that led to a decline in China ＇s potential growth rate, this paper demonstrates that the slowdown since 2012 is not caused by demand-side shock.s＇ but is a natural result of the demographic transition and the change of economic development stage that stemmed from supply-side factors. It is therefore suggested that the demand- side perspective for cyclical analysis must be abandoned and the supply-side perspective for growth analysis ought to be followed Secondly, this paper argues that it is theoretically unjounded and empirically unconvincing for existing literature based on the growth perspective to simply apply the statistical pattern of ＂regression towards the mean＂ to forecast China ＇s growth outlook and thus arrive at pessimistic conclusions. On this basis, this paper identifies a host of initiatives that can significantly increase potential growth rates and proposes policy recommendations for deriving reform dividends foom supply-side structural reform.

Challenges and Opportunities for China＇s Agricultural and Rural Development in the 12th Five-year Plan Period

Despite the great progress of rural socioeconomic development in the 11 th Five-year Plan period （2006-2010）, China＇s agriculture and countryside are still.lacing the challenges of a crude development pattern, backward rural development and cities＇ weak driving effect on the countryside. In the 12th Five-year Plan period （20I 1-2015）, China should transform the way agriculture grows and operates; promote rural socioeconomic development; improve urban planning and its functions, institutional innovation, and urban/rural integration to lay a solid foundation for building an all-round well- off society.

A novel wavelength assignment scheme in OBS network for contention avoidance

Conventional optical burst switching(OBS)technique adopts purely statistical multiplex mechanismso that the bursts collide with each other very easily.To address this problem,a novel proactive con-tention avoidance scheme is proposed,which assigns dedicated wavelengths to each ingress node,then st-numbering algorithm is used to construct the traffic load balanced spanning trees .In this way,contentioncan be eliminated at ingress nodes,and the amount of bursts that could be accommodated by ingressnodes will be maximized.Further,those unused wavelengths left by traffic load balanced spanning treeare also organized as partial trees to carry bursts,thus the link utilization can be improved effectively.Simulation result shows that our scheme can improve the burst loss performance significantly without thewavelength converters or optical buffers comparing to other popular routing and wavelength assignment(RWA)algorithms.

Effect of Seed Drying on Germination Behavior and Seedling Growth of Sweetsop （Annona squamosa）

An experiment was conducted at the Department of Horticulture, College of Agriculture and Natural Resources, Kwame Nkrumah University of Science and Technology, Kumasi （KNUST） Ghana from September, 2009 to April, 2010, to determine the most appropriate drying method, as a post harvest practice, that would ensure high percentage germination ofAnnona squamosa seeds and its subsequent effect on seedling growth. The seeds were sun-dried, air-dried under shade or kept in the fresh state. Five treatments were used, namely, Freshly Sown seeds （Treatment 1, control）, Seeds Air-Dried under Shade for one day （Treatment 2）; Seeds Sun-Dried for one day （Treatment 3）; Seeds Air-Dried under Shade for three consecutive days （Treatment 4）; Seeds Sun-Dried for three consecutive days （Treatment 5）. The experiment was arranged in a Completely Randomized Design （CRD） and replicated three times. Drying of Annona squamosa seeds had significant effect on earliness and number of seeds germinated. Air drying under shade and sun-drying for three consecutive days improved earliness to germination （26 days after sowing） and percent total germination but air-drying under shade had better effect on total seed germination, achieving 90% germination in 42 days after sowing. Furthermore, the prevailing ambient temperature of 30 ℃-32 ℃ enhanced germination of Annona squamosa seeds. The study concluded that for optimum germination, seeds of Annona squamosa should be either air-dried or sun-dried for three consecutive days and be incubated in an ambient temperature range of 30 ℃-32 ℃. In terms of growth, seedling growth in leaf production was better from seeds sun-dried for three consecutive days.

Nanoseparation-lnspired Manipulation of the Synthesis of CdS Nanorods

CdS nanorods have been sorted by length using a density gradient ultracentrifuge rate separation method. The fractions containing longer rods showed relatively stronger oxygen-related surface trap emission, while the shorter ones had dominant band-edge emission. These results suggest that the final length distribution of CdS nanorods is not a result of random nucleation and growth, but is related to the local synthesis conditions. Inspired by these findings, different synthesis environments （N2, air, and 02） have been employed in order to tailor the length distribution. In addition to the rod length, the photoluminescence properties of CdS nanorods can also be manipulated. Increasing the oxygen partial pressure significantly changed the growth behavior of CdS nanorods by improving the anisotropic growth.
