摘要: 利用4个分别适应沙漠地区和阴冷地区的小麦品种, 研究了河西走廊沙漠沿线小麦品种的灌浆特点。春小麦籽粒灌浆的强度较大, 参试品种的平均灌浆强度为1.135g/(d·1000粒)~1.343g/(d·1000粒); 而灌浆的持续时间较短, 参试品种的乳熟期为15d~18d, 灌浆持续期27d~30d。灌浆速率随着日均温和日最高气温的升降有明显波动性。小麦品种之间在灌浆性上有显著差异, 甘春11号和甘春16号适宜在沙漠沿线种植, 与临农14号和陇春8号相比, 在乳熟后期干热风天气过程中受害轻, 灌浆持续时间长3d~7d。甘春16号还具有灌浆强度大的特点。

Abstract: The speed and duration of grain filling were observed at Huangyang town in Hexi Corridor using 4 cultivars of spring wheat(T. aestivum L.). The result showed that the grain filling has high speed and short duration, mean filling intensity of 4 cultivars is 1.135~1.343 g/d. 1000 grain, and filling duration is 27~30 day; the speed of grain filling is influenced by mean and maximum daily temperature during filling period. There are differences in speed and duration of grain filling among cultivars, Ganchun No.11 and Ganchun No.16 adapting desert climate possess the characteristics of higher speed and longer duration of grain filling than other cultivars.
