水稻光周期诱导过程中核酸的变化

水稻光周期诱导过程中核酸的变化 THE CHANGE OF NUCLEIC ACID DURING THE PHOTOPERIOD INDUCE ON RICE 王明全 Wang Mingquan first-author 王延枝 Wang Yanzhi 李雁 Li Yan 从不同次数短日处理的晚稻叶片中提取DNA和RNA,研究了RNA含量的变化对水稻及牵牛花成花诱导的影响。结果表明叶片中RNA的含量随短日处理次数而增加;用生长点已分化的水稻植株的核酸（RNA.DNA）喷施叶面,处理营养生长的水稻,可以促进其抽穗;将短日处理不同天数及光中断处理的水稻叶片RNA,注射到牵牛花幼苗的下胚轴中,RNA的来源不同其诱导成花的效果也不同。表明水稻经一定的光周期诱导后,体内的核酸发生了某种改变。 We examined the RNA and DNA isolated from rice （O. Sativa） leaves which had beed treated with 5, 7, 9 cycles of 10 hour short-days. The results indicated that RNA and DNA stimulated the formation of young panicles in rice and flower bud in morning glory（Pharbitis nil）. 光周期诱导 生长点 分化 核酸 photoperiod induce growing point differentiation nucleic acid 国家自然科学基金(61672102) 1989-01-01 2021-04-01 1
