油菜的生长发育和醣、氮及脂肪代谢特点的初步研究

研究了不同类型油菜品种外部器官的形成、生长与体內醣、氮及脂肪代谢的关系。产量以甘兰类型较白菜类型高。叶面积高峯出现在盛花期前后,净同化率呈“S”形曲线。现蕾抽苔期醣代谢起着主导作用,绝大多数同化产物分配在茎中,同时需肥最多。种子成熟过程含油量的增长,主要由醣转化而成。     

氮肥水平对强筋小麦产量和氮素利用的影响

为明确强筋小麦产量与效率相协同的最优施氮量,试验选用‘济麦20’和‘洲元9369’ 2个优质强筋小麦品种为试验材料,设置0、120、180、240、300 kg N/hm ²等5个施氮水平,用烘干法和凯氏定氮法分别测定小麦成熟期干物质量积累和含氮量,用以计算小麦氮素积累及氮素利用相关指标。结果表明,随氮肥投入量的增加,小麦产量呈现先升高后降低的变化趋势,其中‘济麦20’在N180和N240下达最高产量7.28 t/hm ²和7.26 t/hm ²,其较高的产量主要源于相对平衡的产量构成因素以及较高的干物质积累量（平均18.54 t/hm ²）;‘洲元9369’在N180下产量最高达7.75 t/hm ²,其较高的产量主要源于较高的单位面积穗数(970.65万/hm ²)、穗粒数（30.83粒）、较高的干物质积累量(20.77 t/hm ²)和收获指数(37.33%)。虽然氮肥偏生产力随着氮肥施用量的增加逐渐下降,但两品种的氮肥回收效率、氮肥农学利用率和氮肥生理利用效率均可在N180条件下达到最高值,其中,‘济麦20’最高值分别为62.67%、5.71 kg/kg、9.11 kg/kg,‘洲元9369’的最高值分别为63.65%、7.33 kg/kg、11.55 kg/kg。综合产量水平和氮素利用相关指标,本区域强筋小麦生产中产量与氮素利用效率相协同的施氮量为180 kg/hm ²。     

辽宁春季界限温度发生日期的预报方法研究

为了在春季气候预测工作中,尽可能准确地预测辽宁春季稳定通过5℃的日期,采用1961—2010年辽宁省53站逐日气温资料和NCEP/NCAR再分析的月平均位势高度场、海平面气压场资料以及由NOAA重构的月平均海温场资料,通过相关分析方法并开展物理因子的普查工作,寻找辽宁春季稳定通过5℃日期的影响因子,并利用多元线性回归方法建立预报方程。结果表明：1961—2010年辽宁春季气温稳定通过5℃日期随时间有提前出现的趋势;稳定通过5℃日期与2月北大西洋海温、1月西北太平洋海温、2月北极涛动、1月印度洋海温、10月阿留申低压强度和1月北大西洋涛动关系密切;建立的预报稳定通过5℃日期的多元线性回归方程具有显著意义。     

Resources,representation, and authority in Jharkhand,India

Abstract: Jharkhand is at the centre of India's struggles to define ‘the environment’ and ‘economically relevant natural resources’. Although cultural labels are applied by leaders who seek influence in these struggles as well as by many of those people who listen, an ethnonational analytic frame does not help answer the questions: How, why and when has the political idea of environment changed in India? When and why has the Jharkhand movement chosen violent tactics? When and why has the Jharkhand statehood movement realised electoral success? Or, why was Jharkhand state formed? To address such questions, a long range historical‐institutional approach is much more fruitful.     

Sensitivity of Corn, Oats, Peanuts, Rice, Rye, Sorghum, Soybean and Tobacco to UV-B Radiation under Growth Chamber Conditions

Sensitivity of different agronomic crops to UV-B radiation was studied under environmentally controlled conditions. UV-B radiation reduced plant height, fresh weight, dry weight and ash contents. The reduction varied among the different species tested. Narrow-leaved plants (mainly C₄) were less sensitive to UV-B than broad-leaved plants (mainly C₃).

The origin,evolution, cultivation,dissemination, and diversification of Asian and African rices

Summary Available evidences drawn from biosystematics, evolutionary biology, biogeography, archaeology, history, anthropology, paleo-geology and paleo-meteorology are pooled to reconstruct the series of events that led to the cosmopolitan cultivation of the Asian cultivated rice (O. sativa) and the regionalized planting of the African cultigen (O. glaberrima) in West Africa. The genus Oryza originated in the Gondwanaland continents and, following the fracture of the supercontinent, became widely distributed in the humid tropics of Africa, South America, South and Southeast Asia, and Oceania. The two cultivated species have had a common progenitor in the distant past. Parallel and independent evolutionary processes occurred in Africa and in Asia, following the sequence of: wild perennialwild annualcultivated annual. The weed races also contributed to the differentiation of the cultivated annuals. The corresponding members of the above series are O. longistaminata Chev. et Roehr., O. barthii A. Chev., O. glaberrima Steud., and the stapfii forms of O. glaberrima in Africa; O. rufipogon Griff., O. nivara Sharma et Shastry, O. sativa L., and the spontanea forms of O. sativa in Asia.The differentiation and diversification of the annuals in South Asia were accelerated by marked climatic changes following the last glacial age, dispersal of plants over latitude or altitude, human selection, and manipulation of the cultural environment.Cultivation of rice began in many parts of South and Southeast Asia, probably first in Ancient India. Cultural techniques such as puddling and transplanting were first developed in north and central China and later transmitted to Southeast Asia. Wetland culture preceded dryland culture in China, but in hilly areas of Southeast Asia, dryland cultivation is older than lowland culture. The planting method progressed from shifting cultivation to direct sowing in permanent fields, then to transplanting in bunded fields.Widespread dispersal of the Asian cultigen led to the formation of three eco-geographic races (Indica. Sinica or Japonica, and Javanica) and distinct cultural types in monsoon Asia (upland, lowland, and deep water). Varietal types changed readily within the span of a millenium, largely due to cultivators' preferences, socio-religious traditions, and population pressure. Genetic differentiation developed parallel to the ecologic diversification process.The African cultigen developed later than the Asian cultigen and has undergone less diversification. The wild races in South America and Oceania retain their primitive features mainly due to lack of cultivation pressure or dispersal.Both the African and Asian rices are still undergoing evolutionary changes at habitats where the wild, weed, and cultivated races co-exist.
