The physiological responses under heat stress of plantlets from irradiated bulbs of 3 lily cultivars were investigated.

本文研究了辐射对3种百合鳞茎鳞片扦插幼苗的耐热生理反应。

The effect and its mechanism of temperature during grain filling on rice quality were investigated by using 4 eary-indica rice cultivars with different quality and amylose content. The plants at filling stage were transferred into two phytotrons (Model PGV-36, CONVIRON, Canada), which were set two mean daily air temperatures, i.e. 22℃, optimum temperature regime and 32℃, designed as high temperature regime. The differences in quality properties and starch characteristics of rice between two temperature regimes were determined, and effects of temperature at grain-filling stage on starch biosynthesis in developing rice grains were also analyzed.

本研究以田间异季栽培试验为基础，利用人工气候箱(PGV-36型，CONVIRON)设高温(日均温度32℃)和适温(日均温度22℃)两个典型温度处理，在日温差、光照、相对湿度等因素完全一致的条件下，系统地研究了水稻灌浆结实期不同温度对早籼稻米淀粉的DSC热力学特性、RVA粘滞性、晶体结构、淀粉链长分布等理化指标的影响及其品种类型间的差异，并分析了水稻籽粒淀粉合成代谢过程中几个关键酶的温度效应特征及其与稻米淀粉合成和积累的关系。

In order to identify the proteins which are responsible for the better fruit set in heat-tolerant variety than in heat-sensitive one, we used two dimensional electrophoresis systems to separate isolated proteins from developing anther and looked for the proteins up-/down-regulated in heat-tolerant variety. In doing so, two selected cultivars, CL5915, the heat-tolerant, and L4783, the heat-sensitive, were grown at the same time in a phytotron at both 30/25℃ and 25/20℃. The proteins isolated from developing anthers of heat-tolerant variety grown in 30/25℃, were subtracted to remove the common genetic background.

因此为了鉴定出在高温逆境下与番茄著果率提升有关之蛋白质体，我们利用亚蔬中心所提供耐热番茄(Solanum lycopersicum， formerly Lycopersicon esculentum)品系CL5915与不耐热品系L4783，藉由控制二品系间生长温度之差异（热逆境30/25℃与一般生长环境25/20℃），在雄蕊发育早期利用蛋白质体学技术分析可溶性蛋白质，比较并扣除共有之遗传背景之蛋白质后，将二品系间具有差异的可溶性蛋白质筛选出来，并进一步利用LC-ESI MS/MS进行蛋白质身份鉴定。

With rice cultivars Yangdao 6and Wuyujing 3 as test materials, the effects of relatively high temperature (RHT, mean temperature 30 ℃) at grain-filling stage on the starch viscosity profile and magnesium and potassium contents of rice grain were studied in a phytotron. Four temperature treatments were installed, i.e., RHT at whole GFS, RHT at early GFS and optimum temperature at later GFS, optimum temperature at early GFS and RHT at later GFS, and optimum temperature (CK, mean temperature 23 ℃) at whole GFS.

选用武育粳3号和扬稻6号两个水稻品种，利用人工气候室在水稻灌浆结实期进行控温试验，设置全结实期相对高温、结实前期相对高温、结实后期相对高温、全结实期适温（对照，日均温23℃）对照4个处理，探讨结实期不同时段相对高温（日均温度30℃）对稻米淀粉粘滞性谱和Mg、K等元素含量的影响。
