| Abstract: | The dynamic changes of vegetative nuclei ( VN ),the formation and dismissing of male germ unit (MGU)in pollen tubes were studied by DNA-DAPT fluorescence microscopy together with methyl salicylate clearing technique. Based on the present observations and previously reported facts,the physiological functions of VN and MGU were discussed. The multiplicity of morphology of VN and the presence of associate-DNA between VN and generative cell as well as sperm cells just formed showed that VN may play an important role during the stages of generative cell division,sperm cell formation and development. |
