在南纬27度的6个站的实验种群和野生种群的开花期，观察到无融合生殖胚囊和有性胚囊的发生率变化。差异与花序发育过程中盛行的光周期有关。对日照长度的反应是定量的，在两个菌株中不同。
Changes in incidence of apomictic and sexual embryo sacs were detected in Dichanthium aristatum in an experimental population at 6 stations covering 27 degrees of south latitude, and during the flowering season in a wild population. Differences were associated with photoperiods prevailing during development of inflorescences. Response to length of day was quantitative, differing in the 2 strains.
