Abstract: Investigation was carried out on the relationship between the grain sink strength and starch accumulation of strong and weak grains of three source-limiting rice varieties (Yayou 2, Xiangaiyou 63 and Shanyou63 ) during their development. The results indicated that:(1) There was a close relation betw
