| 摘 要： | 洋麻(Hibiscus cannabinus)一生中叶形态的变化有着一定的规律性(雅库希金1947)。茎上基部的叶子为锯齿卵形,中部为深裂叶,叶子的分裂程度随着叶子的层次逐渐加大,菜片由3裂、5裂、发展到7裂。以后分裂的程度开始下降由7裂降到5裂、3裂。顶端的叶子篇锯齿狭长叶。根据以上的现象,可以看出随着洋麻发育的进程叶片分裂的程度有着周期性的变化。洋麻可以用缩短光照的处理来加速它的开花结实。在短光照条件下的洋麻是否因为光照期的缩短加速了叶形态周期性的变化?当洋麻从短光照的条件下进入长光照之

| Abstract: | Successive leaves of Hibiscus cannabinus on a stem are not alike. The first leafis serriform, and the amount of dissection increases from leaf to leaf until a leaf withseven lobes is reached. This climax type of leaf is followed by a reduction innumber of lobes till the end of growth season. These changes in leaf shapewere called 'by Goebel (1898 ) heterablastic development. Studying the effect of length of day on the heteroblastic development ofHibiscus cannabinus we found that the amount of lobi... |
