| 摘 要： | 以亚麻温敏型雄性不育系1S及其可育系陇亚9号为试材,测定了叶片和花药在不同发育时期的POD活性及IAA、ABA和GA3的含量.结果表明:无论是叶片还是花药,不育系POD活性和ABA含量均明显高于可育系,而IAA和GA3含量均低于可育系.且在花药的发育过程中,二者的差异主要发生在单核期,即不育系小孢子败育的主要时期.据此认为,POD活性和IAA、ABA和GA3含量的异常与亚麻雄性不育的发生有关.

| Abstract: | Thermo-sensitivity male-sterile flax 1S and its normal variety were chosen as experimental material.The activity of POD and the content of IAA,ABA and GA3 were determined in leaves and anthers at different stages.The results showed that a higher of POD activity and ABA content,and a lower content of IAA and GA3 were found in leaves and anthers of male-sterile line.In anthers development stages,the difference happenned mainly in the main pollen abortion stage(monokaryophase).It is suggested that the activity of POD and the content of IAA,ABA and GA3 may be related with the occurrence of male-sterile flax. |
