CM2 68 是中国水稻研究所植物激素研究室新研制的水稻化学杀雄剂 ,经 1994～ 1997年试验表明 CM2 68具有较高的选择杀雄活性 ,在水稻花粉母细胞减数分裂期使用 ,诱导水稻雄性不育效果明显 ,自交败育率可达 95%～ 10 0 % ,化杀制种产量在 1.0～ 1.5t/ hm2 。进一步研究表明 ,CM2 68通过干扰花药中淀粉及蛋白质的积累 ,抑制植物营养体向花药运输脯氨酸及花药自身合成脯氨酸 ,并降低花药中脯氨酸的利用率 ,引起花药营养匮缺 ,导致花粉败育。
CM2 68 is a newly developed rice chemical maleicide developed by Institute of Plant Hormone Research of China National Rice Research Institute. The results of the experiments from 1994 to 1997 showed that CM2 68 has high selective killing activity and is used in meiosis of rice pollen mother cells to induce The effect of male sterility in rice was obvious. The rate of selfing abortion could reach 95% ~ 100%, and the yield of Killing species was 1.0 ~ 1.5 t / hm2. Further studies showed that CM2 68 could inhibit the accumulation of starch and protein in anther, inhibit the production of proline from anther transport ant and anther self-synthesis proline, and reduce the availability of proline in anther, resulting in the lack of anther nutrition, Causes pollen abortion.
