碘元素对提高水稻种子活性及发芽率的影响
|
摘要
为探索碘元素对水稻种子萌发的作用,设置8个浓度的碘溶液对常规早籼稻品种中早39进行引发处理。结果表明,低浓度的碘溶液(浓度为0.0001%～0.001%)能够显著提高水稻种子的活性、提早发芽时间、提高种子萌发的同步性和发芽率。本结果为后续研究碘元素对水稻种子引发的作用机理以及对植株生长及产量的影响奠定了基础。
In order to explore the effects of iodine on seed germination of rice, the seed of early indica rice Zhongzao 39 were soaked under 8 concentrations of iodine. The results showed that low concentration of iodine solution(0.0001%～0.001%)could greatly improve the activity of rice seeds, reduce the time of 50% germination and mean germination time,and improve the synchronicity and germination rate. It is very important to study the action mechanism of iodine on seed priming of rice.
