To ascertain the optimal harvest time of Erigeron breviscapus.
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.
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.
The optimal harvest time of E. breviscapus is in early bloom period after seedling 130 d.
确定灯盏花的最佳采收期。
测定灯盏花生长期不同器官的干物质重量积累以及全株中灯盏花素和咖啡酸酯的含量。
单株叶片数、单叶干重、全株及不同器官的干物质重量在幼苗期130 - 140 d后达到最高。灯盏花素含量随生长期逐渐降低，在幼苗期140 d后急剧下降。咖啡酸酯含量随生长期变化不规则。
灯盏花的最佳采收期为幼苗期130 d后的初花期。
