This experiment induced ZhaoZhong NO.6 and DongHuZhao loquat parthenocarpy by GA3+CPPU to observe the seedless fruit's phenophase,bud spikes,flowers and fruit morphology.We analyzed the fruit growth and development,and explored the flowering habits of the artificially induced loquat parthenocarpy.The results showed that(a) the phenophase of loquat parthenocarpy was advanced by the artificial induction;(b) the buds and fruits became longer;(c) it was dichogamy with the stamen scorched 3-7 days earlier than the pistil;(d) the florescence was shortened;(e) the growth and development of seedless fruits was a single "S" type;and(f) it needed a supply of plant growth regulators during fruit formation and young fruit growth stage in areas of warm climate in the winter.
