Abstract

The cause of flower abortion of Phyllostachys praecox was studied by observation and determination of pollen morphology , vigour , germination rate , pollination capability of stigma and growth of pollen tube .The results are as follows :①Pollen of Ph .praecox is ellipsoidal , with single germination aperture and granular exospore .②Low germination rate of pollen and weak natural pollination capability of stigma are main factors causing flower abortion of Ph .praecox .③Its pollen tube has rapid growth speed and the maximum speed is 3.44 m per minute .This paper offered reference basis for artificial pollination and cross breeding of Ph .praecox.
