不同加速老化条件下高油玉米单交种与普通玉米单交种种子活力的比较

Seed Vigor Comparisons of the High Oil Corn Hybrids and the Common Corn Hybrids Under Different Accelerated Aging Conditions

两个高油玉米的杂交种和两个普通玉米的杂交种被用于在各种老化条件下的种子活力。结果表明高油玉米种子的高含油率可部分导致发芽率、发芽势的减少 ,但不能解释种子活力指数的减少。

Two high oil corn hybrids (HOCH)and two common corn hybrids (CCH) were used to compare the seed vigor under the different accelerated aging conditions The result demonstrated that the high oil rate of HOCH seeds might partially lead to the reduction of percentage germination, germination index, but could not account for the reduction of vigor index The high oil corn did not mean the low seed vigor under the accelerated aging conditions
