| 摘 要： | 笔者于1982—1992年对58个水稻品种(包括杂交组合和制种亲本)进行的观察结果表明:水稻外观形态特征——双零叶、葫芦叶、植伤叶和伸长叶枕距是判断水稻叶片叶龄的依据.在秧田期间可用数记法和种谷方向来判断秧苗的叶龄;在水稻移栽后返青分蘖期,可根据第一双零叶、第一类葫芦叶、植伤叶来判断叶龄的变化;在幼穗分化期,可根据第二双零叶、第二类葫芦叶和伸长叶枕距来判断最后3片叶.

| Abstract: | From 1982 to 1992, based on the observations of 58 rice strains (including parents strains and their hibrid strains) indicated that the external rice leaf. Those characteristics could be double zero leaf(DZL,the leaf cushions of the two neighbouring leaves overlapped or very near by),bottle-gourd like leaf ( BGLL, constricted leaf), injured seedling leaf ( ISL ) and the distance of the leaf cushion between the elongating leaf and the neighbouring leaf ( DLCBEN, During the rice seedling bed stage, the leaf age could be judged by numerical method and the seedling direction. During returned green tillering stage after transplantation, the leaf age could be judged by the first DZL, the BGLL of the first kind and ISL. During young panicle differentiation stage the age of last three blades could by judged by the second DZL, the BGLL of the second kind and the DLCBEN. |
