| 摘 要： | 蔺草草茎长度和是否开过花是决定其品质的两个重要方面。试验表明，不同光周期及光照强度对蔺草的生长和草茎开花率会产生显著影响。生育前期，延长日照显著促进开花，遮光处理降低蔺草的分蘖、草茎长度、减少草茎开花率和每花序小花数。中后期对蔺草进行一定遮光处理后，草茎长度增加，开花率下降。试验表明，光照是造成蔺草开花逆转和影响草茎品质的重要生态因子之一。 |
| 关 键 词： | 生长 蔺草 光周期 光照强度 着花率 草茎长度 草茎品质 |

| Abstract: | Stem length and whether it flowered are two key elements for mat rush quality. The results indicated that different photoperiod and light intensity significantly affected these two ones. In the early growing stage, day extension significantly increased stem flowering rate, lower light intensity by shading reduced the number of tillers, stem length, stem flowering rate and the number of florets per cyme. In the middle and late growing stage, shading within some degree could increase stem length and reduced stem flowering rate. It is suggested that light was one of important ecological factors to result in flowering transition and to affect the quality of mat rush. |
