摘　　要：用SDS-PAGE分析表明:小麦开花后7d出现LMW麦谷蛋白,13d出现HMW麦谷蛋白;花后28d是麦谷蛋白累积的高峰期,36d麦谷蛋白积累量达最大值。麦谷蛋白直接决定小麦面筋的弹性和强度,所以小麦最佳收获期应在开花36d以后。如果过早收获,则会降低麦谷蛋白含量,影响小麦的加工品质。SDS-PAGE analysis confirmed that LMW glutenin began to accumulate 7 days after flowering; HMW glutenin started to accumulate 13 days after flowering} the peak of glutenin accumulation was 28 days after flowering, but glutenin accumulation reached the maximum 36 days after flowering. Accordingly, glutenin of wheat grains can. directly determine the elasticity and strength of gluten in wheat. Therefore,the optimum harvest date of winter wheat is 36 days after flowerihg. If harvested earlier, the gultenin contents in wheat can decrease, thus affecting the wheat processing quality.
