In this experiment, Xuntian969 was used to study the effect of different plant growth regulators on the grain filling characteristics and grain weight in maize.The grain filling process of maize with different plant growth regulators treatment was imitated by Richard Growth equation in order to explain the changes of grain dry matter, grain filling rate and grain weight.The results showed that the increment of grain dry matter in maize with the different plant growth regulators treaments presented a "S"curve change.The grain filling process could be extremely well described by Richard model,since the determination coefficints of Richard equation were between 99.97 and 99.98,which achieved a significant level.The average grain filling rates and the biggest grain-filling rtes were two main elect to affect the same cultivar grain weight, and duration of high-filling rate of kernel was one main elect to affect the different plant growth regulators,YuHuangJin treatments enhanced the final dry matter weight significantly,improved grain filling parameters,finally enhanced the grain weight.

以扬麦11为材料研究了不同氮肥运筹对小麦的生育特点、产量与产量构成的影响，结果表明：随着后期穗肥氮肥使用比例的增加，小麦熟期推迟，全生育期延长，小麦成穗率呈逐渐上升趋势在总施氮量、基肥施用量相同的情况下，增加苗肥比例，小麦高峰苗数增加，最总成穗数也较高。前后期施肥比例为5：5～4：6时，小麦成穗率高，穗粒数多、最终产量较高。增加后期施氮比例，有利于减少无效分蘖，提高小麦成穗率，增加数穗粒数，可以获

紫叶稻的植株体呈紫红色，与常见的绿色水稻差异明显，与绿色植株体主要反射黄绿光不同，其主要反射能量较高的蓝紫光，目前紫叶稻光合特征的报道较少.试验以广西农业科学院水稻研究所选育的紫叶稻(IR1551×珍籼97B)为材料，选用高产广适应性杂交稻汕优63作为对照，研究紫叶稻功能叶的光合特征，探讨群体结构下紫叶稻光能利用特点.2013年早稻季节于广西农业科学院试验基地进行田间试验，高产优化管理模式，采用L
山羊草属(Aegilops genus)是小麦-外源物种远缘杂交和染色体工程育种应用最为成功的种属之一,该属共有23个种,其基本染色体组组成包含C、D、U、S、S1、Ss、Ssh、Sb、M、N和T.为了评价和利用该属物种优异基因,国内外科学家们开展了小麦与山羊草属物种的杂交和鉴定工作.至今,已经获得了15个山羊草物种与小麦的杂交种以及小麦一山羊草附加系近90份、代换系近100份和易位系近50份.
