Abstract

To master the development law of reproduction on Carya cathayensis , flower-bud differentiation was studied by paraffin section .The results indicates that :(1)Stamen primordia form from the apex of a male-flower primordium in the last ten days of March next year , then stamens form and further differentiate in the middle ten days of April .(2)In the last ten days of April , 4 pollen sacs form in a stamen , then tetrads emerge in a pollen sac for pollen mother cellsmeiosis .Later , tetrads are separated to 4 single-cell pollens .Middle layer and tapetum disappear gradually during the pollen development .(3)2-cell pollens form and escape from pollen sacs , and then , inflorescences shed in the first ten days of May .(4)Corresponding relationship is established between external forms and anatomical structure .[ Ch , 1 fig .2 tab .18 ref .]
