山银花(灰毡毛忍冬)适宜采收期研究

Study on optimal harvest period of Lonicera Flos( Lonicera macranthoides)

为了确定山银花(灰毡毛忍冬)的适宜采收期,测定不同发育时期的花蕾外观形态、产量和质量,比较一日内不同时段采摘花蕾的质量。结果表明,开花型和花蕾型灰毡毛忍冬不同发育阶段的花蕾外观形态具有较大的差异;随着花蕾发育,产量逐渐增加;开花型灰毡毛忍冬花蕾开放后(银花期、金花期)绿原酸含量极显著降低,开花前(幼蕾期、青色期、大白期)质量无显著差异;花蕾型灰毡毛忍冬黄白期灰毡毛忍冬皂苷乙显著降低,幼蕾期和青白期质量无显著差异。一日内不同时段采摘的灰毡毛忍冬绿原酸和3,5-二咖啡酰奎宁酸含量有显著差异。开花型灰毡毛忍冬的适宜采收期为大白期,采摘时段为10:00以前和18:00以后,花蕾型灰毡毛忍冬的适宜采收期为青白期,采摘时段为8:00以前和18:00以后。

To ascertain the optimal harvest period of Lonicera Flos（ Lonicera macranthoides）,the configuration,yield and quality of L. macranthiodes bloom verity and bud verity flower at different develop periods were Observed. The quality of L. macranthiodes which harvested at different times of the day was Compared. The configuration was significant difference between different develop period of L. macranthiodes flower. As bud growth,yield increased. Bloom verity of L. macranthoides chlorogenic acid content was significantly lower after opening（ silver flower stage,golden flower stage）,before opening（ young bud stage,green-white stage） have no significant difference of the quality. Bud verity of L. macranthoides macranthoidin B is significant lower at yellow-white stage,young bud stage and green-white stage have no significant difference of the quality. The chlorogenic acid and isochlorogenic acid A content is significant difference between L. macranthoides harvested at different time of the day. The optimal harvest period of bloom verity is the white stage,picking time for 10： 00 before and after 18： 00. The optimal harvest period is the green-white stage,picking time is 8： 00 before and after 18： 00.
