孕穗期湿害对小麦灌浆特性及产量的影响
0
()
摘要:
选用耐湿性不同的三个栽培品种,运用人工模拟湿害的试验方法研究孕穗期湿害对冬小麦灌浆特性及产量的影响。结果表明:孕穗期湿害使籽粒灌浆期缩短;籽粒鲜重,干重下降;灌浆速率降低;单穗结实粒数和千粒重及经济疾病下降。其生理原因是由于叶片Pn,叶绿素含量,单茎绿叶数,单茎地上干重,单茎地下干重和根系活力的下降所致。

Effects of Waterlogging on Filling Characteristics and Yield in Wheat at Booting Stage
()
Abstract:
Effects of waterlogging on filling characteristics and economic yield in wheat at booting stage were tested.The results showed that waterlogging at booting stage led to a shortened filling duration,a decrease in fresh weight,dry weight and grain filling rate of wheat,and the physiological and biochemical reasons for these was due to the decrease in net photosynthesis,chlorophyll content,green leaves number,dry leaf and root weight as well as root activity per wheat plant.
