摘要
目的:研究肉苁蓉生殖生长特性、生长动态及内在质量的变化。方法:在肉苁蓉出土开花期,调查其生殖生长动态,观察肉苁蓉花形态特征及花序生长动态,测定肉苁蓉不同生长阶段的毛蕊花糖苷、松果菊苷含量。结果:肉苁蓉萌动始期为4月上旬,从出土到开花时间约1个月,拱土高峰为4月中旬;出土高峰在4月下旬;现蕾高峰为5月上旬;开花高峰在5月中旬。随着肉苁蓉出土开花,其毛蕊花糖苷、松果菊苷含量下降。结论:肉苁蓉生殖生长阶段持续近2个月左右,出土后花序高度及花穗长度增加迅速,但花序内有效成分含量迅速下降,采收药材宜在早春萌动期。
Objective： To study the reproduction characteristic of Cistanche deserticola. Method： The reproduction characteristic and growing dynamic in Ningxia plantation were investigated, the contents of boschnaloside and echinacoside were determined during reproduction period. Result： The germination period of C. deserticola was in the first ten days of the month, the duration from the germination to flowering lasted about one month. The contents of boschnaloside and echinacoside decreased during reproduction period. Conclusion： The reproduction period of C. deserticolais lasts about two months, germination period of C. deserticola is the suitable harvest time.
