摘要
目的:为确定灯盏花的最佳采收期。方法:观测了灯盏花植株的生长发育进程,全草及各部位的干物质积累规律和全草主要有效成分灯盏乙素和咖啡酸酯含量的积累规律。结果:生育期130 d时,灯盏花单株叶数和单叶干重达到最大,全草及叶、茎和花的干物质积累也较高;灯盏花灯盏乙素含量随生育期推移,而逐渐下降,出苗120 d以后,急剧下降;不同生育时期灯盏花咖啡酸酯含量变化较小,无规律,与灯盏乙素含量无相关关系。结论:灯盏花出苗后130 d,处于初花期,是灯盏花的最佳采收期。
Objective： To ascertain the optimal harvest time of Erigeron breviscapus. Method： The dry matter weight accumulation of different organs in growth process and contents of scutellarin and coffeic acid ester in whole plant of E. breviscapus were determined. Result ： The number of leaves per plant, the dried weight of single leaf and dry matter weight of whole plant and different organs reached the highest after seedling 130-140 d. The content of scutellarin gradually decreased with growth period, and sharply decreased after seedling 140 d. The content of coffeic acid ester varied irregularly with growth period. Conclusion ： The optimal harvest time of E. breviscapus is in early bloom period after seedling 130 d.
