Micro-observation of features of hybrid rice seed
杂交稻种子特性的显微观察

Though hybrid rice show heterosis and sterility, their seed characteri stics are poorer than those of inbred rice. In order to meet the demand of quali ty inspection of hybrid rice seed , the micro-configuration of incompletely clo s ed glumes, germinated seeds on panicle, diseased seeds and clipped stigma traces were observed with electronic scanning microscope. The results laid a foundatio n for extracting features of hybrid rice seed, which is a key to quality inspect ion with machine vision.
