建德市农业技术推广中心完成的该项研究以水稻恢复系花粉为材料,从生物学基础理论着手,开展离体花粉形态变化,生理特性和授粉能力的研究,摸清影响花粉活力的温度、湿度条件,使花粉离体后,活力从原来2—5分钟得以明显延长,实验表明,花粉离体保存30分钟,授粉在不育系上结实率达32.4％;保 Jiande City Agricultural Technology Extension Center to complete the study of rice restorer pollen as a material, proceed from the basic biological theory, to carry out in vitro pollen morphology changes, physiological characteristics and pollination ability to find out the impact of pollen vitality temperature, Humidity conditions, the pollen from the body, the vitality from the original 2-5 minutes to significantly extend the experiment showed that pollen preserved in vitro 30 minutes, pollination in sterile lines on the rate of 32.4%;
