1·In the late of jointing and booting stage rice has highest dry matter productivity.
水稻在拔节孕穗后期干物质生产速率最大。
2·As supplement nitrogen application at booting stage, nitrogen efficiency was the lowest.
孕穗期追施氮肥，氮效率最低。
3·Effects of water stress on growth and yield of rice were studied in jointing-booting stage.
试验研究了拔节孕穗期水分胁迫对水稻生长发育及产量的影响。
4·Mid-booting stage was the most crucial stage affecting brown and milled rice rates, followed by late booting stage.
抽穗前干旱胁迫对糙米率和精米率影响最大的时期为孕穗中期，其次为孕穗后期。
5·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。
6·The diurnal mean CH4 flux from rice-involved plot was significantly higher than that of rice uninvolved plot in the booting stage(P
有植株参与稻田在孕穗期CH4昼夜平均排放通量显著高于无植株参与稻田（P<0.01）。
7·Appearance quality was affected mainly by booting stage for the two varieties. Saving water planning should stared with choice of varieties.
对两个品种来说长穗期是影响外观品质的主要水分敏感期，节水栽培应从品种选择入手。
8·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。
9·Barley crude protein content reduces gradually with growing, the fastest reduced rate is about 40%-50% from middle vegetative period to booting stage.
粗蛋白质含量呈现逐渐下降的趋势，从营养中期到抽穗期下降的幅度最高，达40%—50%。
10·The pot experiment was conducted to study the effects of water stress on photosynthetic and physiological characteristics of rice in early jointing-booting stage.
