光温对蝶豆种子萌发的影响
Influences of illumination and temperature on Clitoria ternatea L.seed germination
摘要
Abstract
[Objective]This research attempted to understand the Clitoria tematea L. seed germination conditions in order to provide theoretical bases for the future artificial planting of C. ternatea L. and to fully utilize relevant resources in future studies. [Method]Using blue-flowered C. tematea L. as test material, the seed germination rate, germination index, vigor index, and seedling growth under the influences of different conditions of illumination, temperature, and warm water soaking were determined. [Result]After 0, 24, and 12 h of illumination, the germination rate of C. tematea L. seeds was 25.56, 23.33, and 21.11%, respectively. At 0 hr illumination time, the germination index and vigor index were the lowest and the seedling growth was at the weakest; in contrast, the seedling growth under other illumination times grew relatively well. Under different temperature conditions, the C. ternatea L. seed germination rate were arranged in the following order from highest to lowest: 30℃>25℃>20℃>35℃>15℃. Between 20-30℃, the seedling growth was excellent, and the germination index and vigor index were significantly higher than those tested under 15℃ and 35℃. Under different warm water temperature soaking conditions, the C. tematea L. seed germination rate were arranged in the following order from highest to lowest: 80℃>60℃>50℃>40℃>70℃>CK. At 40℃ soaking temperature, the germination index, vigor index, lateral root occurrence rate, true leaf growth rate, and seedling growth were all superb. [Conclusion]Temperature was the main determining factor for seed germination growth. The optimal temperature for C. tematea L. germination was between 20-30℃. Under 40-60℃ of warm water soaking, the C. tematea L. germination rate noticeably increased. The influence of illumination on the seed germination rate was negligible, so seed germination was not affected by illumination conditions.关键词
