| 摘 要： | 目的]明确温度对黑龙江玉米生长发育的影响。方法]以吉单261号、吉单505号和龙丰2号为试材,研究了温度对玉米播种-出苗、出苗-抽雄、抽雄-成熟的影响。结果]不同玉米品种的吸水量各异。低温时种子吸水速度明显降低,种子萌发时,低温主要影响种子的吸水量和吸水速度。玉米生育后期,低温主要影响籽粒灌浆速度。吉单261号有较强的耐寒性,其次为龙丰2号,吉单505号耐寒性最差。结论]低温品种间吸水速度差异明显,可将低温下种子吸水速度作为不同品种玉米的耐寒性指标。

| Abstract: | Objective] The aim was to confirm the effect of temperature on growth of corn in Heilongjiang Province.Method] Jidan 261,Jidan 505 and Longfeng 2 were chosen as materials,the effects of temperature on corn seed-seedling,emergence-tasseling,tasseling-maturation were studied.Result] Different varieties water absorption quantity was different.The absorption rate reduced obviously at low temperature,seed soakage and absorption rate was affected by low temperature at seed germination.Grain grouting speed was ... |
