| Abstract: | Black currant stigma is of stigma-wet type.The style is semiclosed and has transmittingtissue.After germinating,the pollens extend downward mainly through the transmitting tis-sue,converge in the stylar canal of the style base,and enter the ovary.And then porogamytakes place.The pollen tube releases its contents through synergid.Female and male gametesfuse 2～4 days after pollination.It is of premitotic type.First the zygote does horizontal divi-sion,then the primary endosperm nucleus splits and developes into endosperm of cellulartype. |
