The conversion boundary of self-incompatibility was researched by sowing by stage. Sunshine of day and temperature was studied critically by investigating leafage and researching traits indoors. The results showed that the daily minimum temperature was the principal factor of affinity conversion and the affinity conversion boundary was 16.5~18.1℃.HE97 was primarily regard as self-incompatible line in this research. The method was by inbreeding and sib HE97, Half the silk of HE97 and Zheng58. Inbreeding and cross have been done simultaneously. The extending condition of pollen tube was observed by dying the silk after pollinating 4 hours. The individuals with pollen tube were observed having seeds, while the individuals without pollen tube were observed having few seeds or no seeds. So this study regard HE97 as sporophytic self-incompatibility .The planting ration of female parent HE97 and male parent 87-1 was 4:1.The nature cross-pollination was studied by the theory of endosperm xenity, the study show that the setting percentage of HE97 was 625%, in which the seed in self was 70% and the seed in hybrid was 30%. This was consistent with the study of silk anatomy structure, then come to the same conclusion: compatible pollen germination and fertilization can stimulate the self-incompatible pollen germination and fertilization in the same corn cob.
通过分期播种,进行了光温敏自交不亲和材料HE97亲和性转换区间的研究,依据田间跟踪调查叶龄及室内考种研究了HE97亲和性转换区间的光温临界值,结果表明:1日最低温度是影响HE97自交不亲和性的主要原因,亲和性转换区间在16.5℃~18.1℃之间。2通过HE97自交和姊妹交以及将HE97与郑58作为双亲,各自的花丝一分为二,分别正反交,授粉后4个小时分别取其花丝进行固定、染色,观察花粉管的伸长情况,根据结实率与花粉管伸长的对应关系,结果发现观察到花粉管的对应植株收获到了种子,而没有观察到花粉管的对应植株结实率极低或没有结实,本研究把HE97初步划为孢子体自交不亲和类型。3以HE97为母本,87-1为父本,按4母:1父行比,通过花粉直感效应研究天然异交率,结果母本HE97结实良好(62%),其中自交粒占70%,异交粒占30%,结合花丝切片观察表明,亲和花粉的萌发及受精会导致落在同一果穗柱头上不亲和花粉的萌发不再受抑制。

On the basis of results of our test,we suggest that low temperature pretreatment changes content of endogenous IAA and iPA of anther,thus interrupts previous developmental direction of pollen and induces microspores develop from a gametophytic way to a sporophytic way.
根据实验结果,推测低温预处理改变了花药内源IAA和iPA含量,阻断了花粉原来的发育方向,使其由配子体的发育途径转向孢子体的发育途径。

Based on these observations, we predict that the transmission of GA-signaling genes occurs in a sporophytic manner, since the protein products and/or mRNA transcripts of these genes may be introduced into pollen-carrying mutant alleles, whereas GA synthesis genes are transmitted in a gametophytic manner, since these genes are preferentially expressed after meiosis.
基于这些观察,我们预测该遗传算法,基因信号传输时,在孢子的方式,因为蛋白质的产品和/或基因这些基因的转录可以引入花粉携带突变基因,而合成的基因遗传传递以配子体的态度,因为这些基因是优先减数分裂后表示。
