通过田间观察和石蜡切片法对桔梗不育和可育花药的形态及其解剖结构进行了比较研究,结果表明:桔梗可育和不育花器形态、花药长度无明显差异,而开花后,可育花药饱满、有光泽、有花粉粒散出,不育花药皱瘪、无光泽、无花粉粒散出;不育花药绒毡层提前退化解体,导致小孢子发育异常.

The comparative study on anther's morphology and anatomy characteristics in Platycodon grandiflorum was carried out between male sterile and male fertility varieties by farming observation and paraffin section method. The results showed that male fertility had no obvious differences with male sterile in morphology and anther's length of flower,but after flowering,male fertility had full and lustrous anthers with pollen granule spilled out,male sterile had shiriveled and lacklustre anthers with empty pollen. Tapetum layer of male sterile was degenerated and disappeared before fertility,leading to the degradation and finally abnormal development of the microspores.
