研究驼绒藜属3种植物开花规律、开花日动态、结实率及柱头微形态。结果表明．华北驼绒藜和驼绒藜雄花开花高峰均在上午8：00—10：00，有利于传粉和受精，而北美驼绒藜雄花在中午11：00-13：00达开放高峰，其雌雄花开花高峰期不一致，不利于传粉、受精，从而结实率降低。三者的开花最适温度基本一致，都在20～24℃。三者的雌花均在下午14：00左右达到开放高峰。雌花柱头微形态研究结果表明，华北驼绒藜的柱头有利于接受花粉，而北美驼绒藜的柱头不利于接受花粉。此外．华北驼绒藜与驼绒藜的雌、雄花花期相遇结实率较高，而北美驼绒藜因花期不遇．故导致结实率低。

A study of 3 Ceratoides species for their flowering habit,daily flowering dynamic change,fertility,and stigma micromophology showed that the male flowers of C. arborescens and C. latens reached their full bloom at 8:00-10:00 am,while the male flowering peak of C. lanata falls on 11 : 00-13 : 00. The bloom peak of the female flowers of all 3 occurred at 14 : 00. Though the most congenial temperature for flowering of all the 3 species was 20-24 ℃, the female stigma micromorphology of C. arborescens was best suited for gathering pollen than the other 2 species. Therefore,C. arborescens boasts the highest seed- bearing rate. Moreover, the flowering period of C. arborescens and C. latens last longer than that of C. lanata, and the highest seed-bearing rate of C. arborescens, and the lowest seed-bearing rate of C. lanata.
