芽鞘色受遗传控制,不同品种,其芽鞘包各有不同,而且芽鞘色又不受环境影响。根据这一特殊的稳定性状,用芽鞘色鉴定品种纯度,效果比较可靠。鉴定方法:可结合种子发芽试验进行。以水稻为例;从发芽试验的样本中取200粒(分2组)饱满的发芽率高的种子,放置湿沙(纸)的播种箱或皿中,为了加速发芽,可将样本放在25～30℃的恒温箱中(籼稻一般7天,粳稻10天),然后逐粒平整铺粘在白色吸水纸上,再用无色玻璃板盛夹扦置
Bud sheath color by genetic control, different varieties, their bud sheath different, and bud sheath color from the environment. According to this special stability traits, identification of varieties with bud sheath color purity, the effect is more reliable. Identification method: can be combined with seed germination test. Take rice as an example. Take 200 seeds (divided into 2 groups) full of seeds with high germination rate from the germination test samples and place them in a sowing box or a dish of wet sand (paper). In order to accelerate germination, ~ 30 ℃ incubator (indica generally 7 days, japonica rice 10 days), and then the grain tablets spread on the white absorbent paper, and then the folder with colorless glass Sheng device
