| 摘 要： | 通过对不同类型玉米子粒发育动态比较研究发现，败育粒在授粉前期其子房长度及重量就明显低于正常子粒。随授粉后天数的增加，其差距日渐扩大，约在授粉后8～12d(8－12DAA)停止发育转向衰退。子粒败育过程可区分为两个阶段：0－8DAA为败育诱导期，8－16DAA为表观衰败期。在子粒败育诱导期，糖分及蛋白质浓度并不低。研究认为，顶端子粒的败育可能与其库活性较低有关。

| Abstract: | A comparative study was conducted with two kinds of maize genotypes.1he results were as follows;The ovary length and weight of the abortive kernels were lower than that of well developed kemels.As the increasing of Days After Anthesis(DAA),the difference between the kernels was enlarged.The caurse of kernel abortion can be divided into two phases:0-8DAA was the inducing phase,while8-16DAA was the obviously degrade phase.The content of sugars.and protein of aborted kemel was not lower than that of well developed kemel.It can beconcluded that aborted kernels at the ear tip have a close relations with their low sink strength. |
