| 摘 要： | 以籼稻品种扬稻6号为材料,经甲基磺酸乙酯(EMS)诱变后,选择芽期胚芽鞘斜着出土,苗期向上斜着生长(呈43°±25°的角度),随后各分蘖逐渐向下弯曲,至孕穗期呈匍匐生长表型,随着节间的伸长,在各节点处发生向下弯曲,但节间不弯曲,至成熟期整个植株呈"吊兰"状的突变体.对其农艺性状与野生型进行比较分析,结果表明,两者的叶长、叶宽、叶角、穗长、分蘖数等性状存在显著性差异.对该突变体细胞进行光镜和电镜观察发现,野生型与突变体在细胞形状、造粉体分布、液泡大小、细胞壁上物质分布等方面均存在着明显的差异.

| Abstract: | A rice gravitropism mutant from M1 population of Indica line Yang Dao 6,which was treated by EMS was obtained.The characters of the mutant including prostrate growth and down-growth was studied.The difference of some agronomic characters,including the length of leaf,the width of leaf,the angle of leaf,the number of tillers,et al.was obvious.but the character of grain had no difference.Microstructure between WT and SGRM mutant showed obvious difference in the point of cell figure,distributing for amyloplasts,size of vacuole,substance on cell wall,et al. |
