- Abstract:
- Chestnut has a large growing area in Yunnan，but in actual production,the yield of chestnut has not been high.In this test,chestnut variety of ‘Yongfeng No.1’ were used as test materials,using the method of paraffin section to study the gender differentiation of chestnut in Yunnan.The results showed that,hermaphrodite inflorescence primordium appeared in early March,female flower cluster primordium formation appeared in mid-May,at the end of May,the formation of four ovule primordia appeared,split megaspore,in early June eight nuclear embryo sac formed,anatropous,bitegmic and crassinucellate.The four body was linear,female internal development and external morphological characters had certain correlation.
