不同含水量条件下玉米种子包膜对自身吸水过程及幼苗生长发育的影响

The Influences of Seed Coating on the Delaying Seeds Imbibition and Seeding Growth Under Different Levels of Water Stress

在不同水分条件下种子包膜能有效地延迟种子吸水,且不影响出苗和幼苗生长。在盆栽逆境水分条件下,包膜种子能明显提高出苗率,与对照相比能有效地提高幼苗鲜重和干物重,增加叶面积、根系数量、茎基周长以及矮化幼苗以促进苗壮。

Seed imbibition was effectively delayed by the seed coating under different water stress, otherwise the emergence was not infected by the seed coating. The emergence rate was highly improved by the coating under water stress. The traits included seedling weight, dry weight, leaf area, root number, stem diameter were all improved by the seed coating according to the check plant. The hight was reduced so that the seedlings were very stronger.
