- 摘要:
- 以大花卫矛为试材，于2013年10—11月采用分光比色法，测定了大花卫矛叶片叶绿素、类胡萝卜素、花青素的含量，并探讨各色素与温度因子的关系。结果表明：在10—11月大花卫矛叶片变色过程中，随着时间的变化叶片中叶绿素a含量、叶绿素b含量和叶绿素a+b含量呈明显下降的趋势，其中叶绿素a含量下降幅度为79.1%，叶绿素b含量下降幅度为88.8%，叶绿素a+b含量下降幅度为80.9%，类胡萝卜素含量下降幅度为44.1%。随着时间的变化，花青素含量呈明显的上升趋势，上升幅度为2 063.6%。叶绿素含量与平均最高和最低气温呈极显著正相关，类胡萝卜素含量与日平均最高和最低气温呈显著正相关，花青素含量与日平均最高和最低气温呈极显著负相关。
- Abstract:
- Taking Euonymus grandiflorus as test material，the changes of the concents of chlorophyll，carotenoid and anthocyanin of leaves in Euonymus grandiflorus were measured continuously by using spectrometer from October to November,and the relationship between the contents of pigments and the temperature changing was also explored.The results showed that the chlorophyll a，chlorophyll b,and the total content of chlorophyll of Euonymus grandiflorus were all decreased significantly from October to November in a whole．Chlorophyll a content was decreased 79.1%，chlorophyll b content was decreased 88.8%，the total content of chlorophyll was decreased 80.9%.Carotenoid content also was decreased from October to November，and the descend range was 44.1%.The content of anthocyanin was rised obviously during the different time.The range was 2 063.6%.The content of chlorophlly was very significantl postively correlated with the highest average temperature and the lowest average temperature.The content of carotenoid was significantl postively correlated with the highest average temperature and the lowest average temperature.The content of anthocyanin was very insignificantly negatively correlated with the highest average temperature and the lowest average temperature.
