河北省农科院粮油作物研究所研究成功了一项鉴定花粉植株倍性的简易方法,即叶片保卫细胞长在60-65μm以下均为不育株。该法准确率超过95％。具体做法是,取移栽成活后处于分蘖盛期的花粉植株主基第2叶长1.5—2cm叶尖,用解剖刀刮去上表皮和叶肉,留下一层无色下表皮制片观察,用醋酸洋红染 Hebei Academy of Agricultural Sciences, Institute of Cereals and Oils Research successfully identified a ploidy pollen plant a simple method, that leaves the guard cells are 60-65μm in length are sterile. The accuracy of the law more than 95%. The specific approach is to take transplanting surviving in the tillering stage pollen plant main base of the second leaf 1.5-2cm long tip with a scalpel scrape the epidermis and mesophyll left a layer of colorless epidermis filming observations, Dyed with acetic acid magenta
