| 摘 要： | 研究不同真叶期的大麻在短日照处理(每天8 h自然光照、16 h黑暗)下开花所需时间、生长状况及性别表达的变化情况.结果表明,短日照处理可促使大麻提前开花,大庥3～4对真叶期是进行短日照处理的最佳时期;短日照处理对大麻的性别分化无显著影响;大麻是研究植物性别分化表达的良好材料. |
| 关 键 词： | 大麻 短日照 开花时长 性别表达 |

| Abstract: | The length of inflorescence time,growth status and sex expression in C.sativa with different pairs of visible leaves were studied by the short daylight treatment(8-h/d photoperiods,16-h/d darkness).The result showed that short daylight treatment impelled inflorescence ahead,the best phase of treatment was 3-4 pairs of visible leaves.Through short daylight,obvious effect was not found on the sex expression in C.sativa;C.sativa is a favorable material to study the plant sex expression. |
| Keywords: | Cannabis sativa L short daylight length of inflorescence time sex expression |
