摘要
本文旨在探讨Ca^(2+)、Na^+处理对水分胁迫下小麦种子发芽势、发芽率及幼苗生长的影响。实验初步表明,用0.10％—0.35％Ca^(2+)、Na^+处理小麦种子18h,在水分胁迫下其发芽率、根冠比、幼苗鲜重都显著高于水处理情形,其中又以0.25％Ca^(2+)、0.20％Na^+处理浓度效果最好。
The paper studide effect of Ca2+、Na+ pretreatment on germination and seedling growth of wheat under water stress The results showed germin - ation capacity root shoot ratio and fresh weightof seedling were strikingly biger with Ca2+ 、Na + pretraatment for 18 hours than water of, some of 0. 20%Na+ pretreatment were best
