In order to culture the regenerated stamens of hyacinth in vitro to maturity,the effects of temperature on regeneration of stamens,microsporogenesis and pollen development were studi- ed.Results showed:the proper temperature for stamen regeneration was 25℃.The tempe- rature going down gradually was advantageous to the microsporogenesis and pollen develop- ment.The most suitable temperatures for differentiation of microsporocyte,meiotic division and pollen first mitosis were 20—25℃,20℃ and 10℃ respectively.U...
