摘要
目的 研究头花蓼开花结果与授粉特性。方法 采用固定植株跟踪观察法，观察研究头花蓼开花习性及授粉特性。结果 头花蓼4～6月形成头状花序，并边开花边结果，盛花期为8～10月，盛果期为9～11月；异花授粉为头花蓼的主要授粉方式，其中自然授粉的结实率最高。结论 异花自然授粉为头花蓼的主要授粉方式，头花蓼的果实采收时间以9～11月为佳。
Objective To study on relations between the blossom and bear fruit with pollination characteristic of Polygonurn capitaturn Buch. -Ham. ex D. D. Methods To adopt fixation of plant tracking observation, study and observe the effects of pollination for the habits and characteristic of blossom from Polygonurn capitaturn Buch.-Ham. ex D. D. Results Formed head inflorescence and the bear fruit while blossom from Apr. to Jun. , Aug. to Oct. was the stage of full bloom, but Sep. to Dec. is the stage of full fruit. Cross-pollination is the main pattern , but the highest ripening rate was spontaneous pollination of Polygonurn capitaturn Buch. -Ham. ex D. D. Conclusion The main pollination was to adopt spontaneous cross-pollination , and it was the most suitable fruit harvesting stage from Sep. to Dec.
