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.     

不同蔬菜对重金属汞、铬、砷、镉、铅积累效应的研究

为了对辽宁省葫芦岛龙岗区蔬菜生产基地蔬菜生产结构的调整提供科学的参考,采用原子吸收的方法,对该生产基地的土壤与蔬菜中重金属(Hg、Cr、As、Cd、Pb)的含量进行检测。结果表明：该蔬菜基地土壤中Hg的含量平均为0.42 mg/kg,Cr的含量平均为52.20 mg/kg,As的含量平均为34.92 mg/kg,Cd的平均含量为0.93 mg/kg,Pb的含量平均为98.49 mg/kg,说明该地区的土壤中重金属含量基本符合农业生产的要求;该蔬菜基地蔬菜中Hg的含量平均为0.92 μg/kg,Cr的含量平均为120.09 μg/kg,As的含量平均为13.80 μg/kg,Pb的含量平均为94.17 μg/kg,Cd的平均含量为15.65 μg/kg,并且所测定的蔬菜样本中甘蓝在5种重金属的含量上均比其他蔬菜的含量高,但也能符合国家卫生标准。此实验可为该蔬菜区蔬菜生产结构的调整提供一定的参考。     

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).

CuSO4、MgSO4、FeSO4对绿豆 N、P、K含量的影响

选用绿豆品种白绿9号,用浓度均为50mmol/L的CuSO₄、MgSO₄、FeSO₄溶液进行浸种、喷施、浸种+喷施处理,以蒸馏水处理为对照。探讨绿豆分枝期、开花期、成熟期Cu ²⁺、Mg ²⁺、Fe ²⁺各处理对绿豆根系、叶片、茎秆部位N、P、K含量的影响。结果表明：Cu ²⁺、Mg ²⁺在3个时期对N、P含量的降低作用较强,尤其降低P含量更强,且Cu ²⁺强于Mg ²⁺;Cu ²⁺、Mg ²⁺对K含量有增加作用。Fe ²⁺从分枝期到成熟期对N、P、K含量一直起着增加作用。     

槟榔叶片产量水平、生长年限、黄化病对叶片微量元素含量的影响

以海南东中部正常结果与黄化槟榔叶片为试验材料,采用田间调查与实验室分析相结合,分析4个产量水平(高产组、中高产组、中产组、低产组)中4个生长年限(10,15,20,25年)正常结果与黄化槟榔叶片Cu、Zn、B、Mo、Fe、Mn含量变化。结果表明:黄化槟榔叶片Cu含量最高,比中产组和高产组的高,但差异不大,高产组的最低。低产组槟榔叶片Zn、B、Mo、Fe、Mn含量分别比高产组的低47.7%,22.5%,49.0%,40.8%,58.8%。黄化组槟榔叶片Zn、B、Mo、Fe、Mn含量比高产组分别低44.8%,30.6%,54.4%,50.9%,62.6%。而比低产量的低5.5%,10.4%,10.7%,17.0%,9.2%。高产组与中高产组槟榔叶片Cu含量随着生长年限有所降低,但差异不显著。中产组槟榔叶片Cu含量随着生长年限无直线变化规律。4个产量水平槟榔叶片Zn、Mn、Fe含量随着生长年限呈降低趋势,4个产量水平中不同生长年限槟榔叶片B、Mo含量差异不显著,其含量随着生长年限无明显直线变化趋势。结论:黄化槟榔叶片Cu含量较高,受生长年限影响不明显。槟榔产量水平、黄化病对叶片Zn、B、Mo、Fe、Mn含量的影响较大。高产组槟榔叶片Zn、B、Mo、Fe、Mn含量较高。带有黄化槟榔叶片Zn、B、Mo、Fe、Mn含量最低。槟榔生长年限对叶片Zn、Fe、Mn含量有一定影响。而对B、Mo含量变化无明显影响。
