Abstract:

Taking twenty years old pear of floral organ mutation with genetic stability as materials，the bud growth，pollen germination rate and external morphological were analyzed.The results showed that the mutant strain of flower development and normal development of the most obvious difference were the flower petals with complete or partial deletion of a corresponding increase in the corresponding position of the stamen filaments；anthers of petals corresponding location were large；pollen germination rate was high；the partial specialization petals on the hygiene of anther.According to the experimental results，concluded that the mutant was pear floral homeotic mutant strains，the control of floral organ development B function area produced mutations were the cause of flower organ abnormality.It was possible that the mutant strains provided the further understanding of the internal control mechanism and flower development mechanism of flower development.
