水稻起源于热带和亚热带,对低温十分敏感,当温度低于15℃时水稻便无法正常生长。有统计显示,每年低温冷害导致我国水稻减产约50亿kg。近年来,因直播稻大面积推广以及水稻种植区域不断由热带、亚热带向高海拔、高纬度地区扩张,水稻遭受低温冷害的频率有增加趋势。低温冷害已成为限制我国水稻生产的一大瓶颈。因此,挖掘调控水稻耐冷性的关键基因,研究其作用机理,对防控水稻低温冷害具有重要意义。

万建民 水稻褐飞虱 基因
2023/10/28
褐飞虱是水稻生产中最严重的害虫。褐飞虱通过针状口器刺入水稻叶鞘组织吸食韧皮部汁液,造成水稻严重减产甚至绝收。种植抗性品种是综合防控褐飞虱的基础。然而植物抗病虫性通常受光照、温度和湿度等环境因素的影响,在一定程度上制约了抗性基因的有效利用。如采用密植的栽培方式是当前许多作物增加单位面积产量的重要途径,但是密植通常会导致冠层以下的植株部分光照不足而产生庇荫反应,易滋生各类病虫害,虽然这种现象普遍存在,...
