本研究的第Ⅰ报业已报道,稻米胚乳淀粉细胞的数目、细胞的大小及其形状与垩白性状有密切的关系,固而对稻米品质有一定的影响。有人曾多次报道,垩白性状受环境条件的影响。但胚乳淀粉细胞的数目、大小及其形状是否也受环境条件影响,未见报道。 为了探明不同生态条件,特别是籽粒灌浆成熟期的不同气温对稻米胚乳淀粉细胞的影响,本研究以不同播种期、不同海拔高度
The first newspaper in this study has reported that the number of endosperm cells in rice endosperm, cell size and shape and chalky traits are closely related, but the quality of rice has a certain impact. It has been repeatedly reported that chalky traits are influenced by environmental conditions. However, the number of endosperm starch cells, size and shape are also affected by environmental conditions, has not been reported. In order to find out the effects of different temperatures on the starch cells in endosperm of rice under different ecological conditions, especially the grain filling maturation stage, we studied the effects of different planting seasons, different altitudes
