1·As supplement nitrogen application at booting stage, nitrogen efficiency was the lowest.
孕穗期追施氮肥，氮效率最低。
2·The types of the 15 varieties might be considered into 6 types on the basis of their cold tolerance at booting stage.
根据这15份材料的孕穗期耐冷性特征，将它们的耐冷型划分成6类。
3·The results also showed that waterlogging affected 32P absorption, transportation and distribution in wheat at booting stage, and speeded up senescence of root system consequently.
同时，孕穗期土壤渍水逆境严重影响根系吸收、运输和分配32P的能力，从而加速了根系衰老。
4·It was observed that the application of nitrogen fertilizer at booting stage could increase glutenin content markedly, which was favorable for the improvement of wheat processing quality.
孕穗期施氮可以明显提高子粒麦谷蛋白的含量，有利于小麦加工品质的改善。
5·The higher grain yield in mutated strains was mainly due to increasing the net photosynthetic rate and apparent quantum yield considerably at the stage from booting to filling.
孕穗-灌浆期的净光合速率和表观量子效率的急剧增加可能成为突变株系增产的主要原因。
6·A major gene was found to control cold tolerance in Kunming Xiaobaigu. Cold acclimation is presumed to be one of the approaches by which rice genotypes may acquire cold tolerance at the booting stage.
昆明小白谷耐冷性是受主效基因支配，冷驯化是水稻微效耐冷基因累积获得穗期耐冷性的途径之一。
7·The application of S-07 solution at the booting stage could decrease the IAA content of vigorous spikelet, but increased that of weak spikelet.
孕穗末期喷施S-07溶液可降低强势粒但提高弱势粒灌浆前期的内源IAA水平。
8·Subjected to drought at the tillering stage will reduce the rice panicles, the effect of drought on rice panicles at the booting stage and full heading stage is little.
分蘖期水稻遭受干旱会降低水稻的有效穗数，孕穗期和齐穗期水稻遭受干旱对水稻的有效穗数没有影响。
