不同地理来源的蔗茅无性系集中种植后的抽穗期与原生长地海拔高度有明显相关: 海拔< 1 500m , 抽穗期随海拔升高而延迟; 海拔> 1 500m , 抽穗期随海拔升高而提早。其花药减数分裂时的染色体配对构型略有差异, 但2N= 20 未发现变异。蔗茅同一个体不同小穗内的花药数目的变异为0 ～3 枚; 其花粉量适中, 花粉发育良好, 是甘蔗杂交育种中很有利用价值的优良父本。 The heading date of cultivated Cimici clones with different geographic origins was significantly correlated with the original growing altitude: altitude <1500 m, heading time delayed with increasing altitude; altitude> 1 500 m, heading time increased with altitude Early. The chromosome pairing configuration at anther meiosis was slightly different, but no mutation was found at 2N = 20. The variation of the number of anther in different spikelets of Cimicifuga ordosica was 0 ~ 3. The pollen amount was moderate and the pollen was well developed, which was an excellent male parent in the cross breeding of sugarcane.
