观察含色素种类和色素分布位置明显不同的五个杂交品种后发现 ,色素在播种 3～ 5d的籽苗中初现 ;同一品种的初生结构与次生结构中红色素的分布格局大致相同 .红色素在红皮品种产品器官的表皮、周皮和其内方局部细胞中以镶嵌型分布为主 ;在绿皮红肉品种中呈弥散分布 ,在产品器官的韧皮部、初生木质部周围和三生结构中色素较多 ,在叶柄和叶脉基部也有分布 .荧光显微观察发现 ,在红色素密集区细胞中 ,含有与叶绿体荧光相似的小颗粒 .绿色色素一般集中在叶绿体中 .讨论了色素形成部位、发育规律及其与遗传的相互关系 .
After observing the five hybrids with different pigment types and different pigment distributions, it was found that the pigment appeared in the seedlings of 3-5 days after sowing. The distribution patterns of the red pigment in the primary and secondary structures of the same variety were similar. Pigments mainly distributed in the epidermis, periderm and local cells in the erythrocyte product organs in a mosaic pattern, and dispersed in the green red meat breed. In the phloem, primary xylem and trigeminal structures There are more pigment in the petiole and vein base also distributed.Fluorescence microscopy found that in the red pigment-intensive cells, containing chloroplast fluorescence similar to the small particles.Green pigment is generally concentrated in the chloroplast.This paper discusses the pigment forming site, Developmental regularity and its relationship with heredity.
