| 摘 要： | 研究了甘蓝型油菜种子发育过程中种皮色泽的变化．结果表明：甘蓝型黑籽油菜和黄籽油菜一样，在种皮上均可能出现褐色斑点，开花后５０天内，黑籽和黄将油菜的种皮颜色没有显著差别．５０天后，黄籽油菜从种子的合点出开始退绿变黄，种脐变成褐色，黑籽油菜从种子的合点端开始变成紫红色或褐色，以后紫绿相间，直至全紫或是暗褐色为止．种皮的颜色主要是由栅栏层细胞中沉积色素决定的．还观察到糊粉层上有一些突起的黑色颗粒状物质．

| Abstract: | Changes of seed-coat colour were studied in different developmental stages of rapeseed (Brassica napus L.). The results showed that black spot appeared along the surface of the seed-coat between yellow-seed and black one. Within 50 days after flowering,there were not significant changes of seed-coat colour between yellow-seed and black one;but significant appearance after 50 days of flowering, chalazal end of green-seed in yellow seed rapeseed faded from green into yellow, and hilum turned into black in yellow-seed,while chalazal end of green-seed in black-seed rapeseed fade from green into purple-red or dark brown. Seed-coat colour were mainly decided by the pigment within palisade fanger, and some black particles were also detected in the aleurone layer. |
