高粱雄性不育系植株被高温激发产生可育的黄花药的现象表明,这些植株本身已含有产生可育黄花药的物质和雄性可育基因的存在,但可能被调节因子所抑制。对花药的同工酶电泳分析得到了证明。雄性不育系的黄花药和白花药的酶谱,在单核花粉粒时期有与雄性可育系植株(保持系)相同形式的区带,当发育到三核花粉时期,白花药的某些区带消失,而黄花药则保留了与雄性可育系植株相同的区带。试验还指明了出现黄花药的临界温度为39—40℃和花粉母细胞时期为其对温度的敏感期。
The phenomenon that plants of sorghum male sterile lines were induced to grow fertile florescence by high temperature shows that these plants themselves contain the materials that produce fertile honeysuckle and the male fertile genes but may be inhibited by regulatory factors. The anther isozyme electrophoresis analysis has been proved. The zymogram of the yellow and white anthers of the male-sterile lines has bands in the same form as the male-fertile plants (maintainer lines) during the mononuclear pollen stage and when developed to the triple-nucleus pollen stage some of the white anthers The zone disappears, whereas the yellow flower retains the same zone as the male fertile line. The experiment also indicated that the yellowing drug appears to have a critical temperature of 39-40 ° C and the pollen mother cell period is its temperature sensitive period.
