摘要
为了探讨提高麻疯树雌雄花比例的方法,以提高麻疯树的生产能力,进行了激素KT对麻疯树头茬花的诱导试验。结果表明,不同浓度中以3 mg/L激动素KT对雌雄花比的影响最大,雌雄比为1∶11.9;5 mg/L激动素KT对雌、雄花的分化均表现出促进作用。激动素KT对雌花和雌雄比的诱导率在浓度为1~3 mg/L时随着浓度的增大而增大,之后则呈降低的趋势。
The first Jatropha curcas flowers were treated with diffent kinetin concentration to study the effect on its female-male ratio for improving productivity of Jatropha curcas.The results showed that the female-male ratio of first Jatropha curcas flowers trested with 3 mg/L kinetin was up to 1∶11.9,5 mg/L kinetin could promote differentiation of female and male flowers,and the induction rate of female flowers and female-male ratio of first Jatropha curcas flowers increased with increase of kinetin concwntration when kinetin concentration was 1~3 mg/L.
