绿豆人工杂交技术绿豆是自花授粉作物,因其闭花授粉的特性,天然异交率极低;由于其蝶形花冠和盘曲的柱头等特点,按常规杂交技术其结实率也相当低。据张噗研究:尽量安排在当地昼夜温度25-20℃左右开花,于上午10时至下午1时进行人工杂交。选择适宜的花梗,每花...
Mung bean artificial hybridization technology Mung bean is a self-pollination crop, because of its closed-pollination characteristics, the natural rate of outcrossing is very low; due to its butterfly-shaped corolla and Tragopan stigma and other characteristics, according to conventional hybridization its seed setting rate is quite low. According to Zhang Pu study: try to arrange the local day and night temperature of about 25-20 ℃ flowering, at 10 am to 1 pm artificial hybridization. Select the appropriate pedicel, each flower ...
