摘要
The floral organ morphology,pollen morphology,quantity,and viability of Rumex,Rumex hanus F1,Rumex hanus 1,and Rumex hanus 2 were compared and analyzed.The results showed that the longitudinal diameter of petals was not significantly different among different varieties of sorrel,and the transverse diameter and corolla diameter showed differences to varying degrees.They all had six stamens and three stigmas.The pollen shape of the four varieties was prolate,and the polar view was trilobated and round.They all had three germinal furrows,and the outer wall of the pollen was decorated with small cavities and spiny patterns,with warty protrusions.The equatorial axis length of pollen of different varieties of sorrel was significantly different(P<0.05).There were no significant differences in pollen amount among different varieties.There were six anthers in a single flower,featuring anther dehiscence.The pollen viability of Rumex hanus 1 was significantly lower than that of the other three varieties(P<0.05).Therefore,through the analysis of the floral organs and morphological characteristics of anthers of sorrel,the varieties of sorrel can be effectively distinguished and identified.
以鲁梅克斯、食叶草F1、食叶草1、食叶草2为材料,对其花器官形态以及花粉的形态、数量和生活力进行比较分析。结果表明:不同酸模品种的花瓣纵径差异不显著,横径和花冠直径呈现出不同程度的差异,雄蕊数均为6个,柱头数均为3个;四个品种的花粉形状均为长球形,极面观3裂圆形,均具有3条萌发沟,花粉外壁具小穴-刺状纹饰,并有疣状突起;不同酸模品种的花粉赤轴长差异显著(P<0.05);花粉量在各个品种间差异不显著,单花花药数量均为6个,花药特性均为开裂;食叶草1的花粉生活力明显低于其他三个品种且差异显著(P<0.05)。因此,通过对酸模花器官和花药形态特征进行分析,可以有效区别和鉴定酸模品种。
