分别以耐高温、中度敏感与敏感型3个棉花品系为材料，分析了它们在不同发育时期叶片和花药中SOD、POD、CAT保护酶活性和MDA含量的差异及在盛花期高温胁迫下的变化。3个品系间叶片保护酶活性在苗期和盛蕾期几乎相同，在盛花期和结铃盛期耐高温显著高于敏感类型，而耐高温棉花叶片MDA含量自盛蕾期起显著低于敏感类型。花药保护酶活性随生育进程而逐渐增加，耐高温棉花花药SOD和POD活性在花粉粒成熟期才显著高于...

CO2 enrichment Growth stage Flowering Pod set Raceme order Soybean
2009/7/28
The objective of this study is to elucidate the effects of CO2 enrichment during different growth periods on flowering, pod set and seed yield in soybean (Glycine max (L.) Merr.). Soybean cultivar ‘Fu...
Effects of Source/Sink Ratio and Cytokinin Application on Pod Set in Soybean
Cytokinin Flower abortion Glycine max Photoassimilate Pod set Source/sink ratio Soybean
2009/7/24
A large proportion of soybean flowers abort during development. Pod set is significantly affected by the availability of assimilate and cytokinin in the flowers, but their synergistic effects on pod s...
Pod Dehiscence in Soybean:Assessing Methods and Varietal Difference
Desiccator method Moisture content Oven-dried method Pod dehiscence Relative humidity Soybean Strain gauge method Varietal difference
2009/7/24
The varietal difference of pod dehiscence in 25 soybean cultivars consisting of 16 Japanese and 9 Thai cultivars was examined at 3, 5, 7, 14, 21, 28 and 35 days after placing in a desiccator (desiccat...
Pod Dehiscence in Relation to Pod Position and Moisture Content in Soybean
Moisture content Pod dehiscence Pod position Soybean Strain gauge method
2009/7/23
The relationship between pod dehiscence and the position and moisture content of pods was examined in two soybean cultivars, Fukuyutaka and Keito-daizu. The frequency of pod dehiscence at different pa...
A Major Soybean QTL,qPDH1,Controls Pod Dehiscence without Marked Morphological Change
Glycine max(L.) Merr. Pod dehiscence QTL Near-isogenic lines (NILs) Pod morphology
2009/7/21
Pod dehiscence (shattering) is a major source of yield loss in the mechanically harvested soybean. We examined near-isogenic lines (NILs) for a major quantitative trait locus (QTL) controlling pod deh...
生理高温（38±1）℃ 处理转基因烟草品系及非转基因品系的幼苗，测定其SOD,丙二醛、可溶性糖含量、电导率和生物量等指标。结果表明，转基因品系SOD的活性更强，丙二醛的含量更低，生物量受到的影响更小。由此认为，转基因烟草品系幼苗比非转基因品系的抗热性更强，其中转基因POD高表达烟草品系的抗热性最强。研究结果表明通过转基因方法提高植物的抗热性是可行的。
