小麦不同千粒重标志着籽粒的饱满度,即种子胚乳养分含量的差异。同一品种在同一穗头上,其籽粒饱满程度差异较大,如目前我省推广的小麦良种鄂思1号属大粒型,其千粒重大粒平均达55.7克,小粒仅37.76克,相差17.94克。我们将不同粒重的麦种分别种植,观察,比较其对后代的影响。 1.越冬前麦苗生育状况 小麦籽粒大胚乳营养 Different thousand-grain weight of wheat marks the fullness of the grain, that is, the difference of the seed endosperm nutrient content. The same species in the same ear head, the full extent of the difference in its grain, such as the current promotion of wheat varieties in our province Ersi large grain type, the average grain weight of 55.7 grams, only 37.76 grams of small grains, a difference of 17.94 grams. We planted wheat grains of different grain weights, observed them, and compared their impact on future generations. 1. Pre-winter wheat seedling status Wheat grain endosperm nutrition
