Abstract:
In order to reveal the process and characteristics of reproduction of introduced ‘Yanlong’ chestnut and and local ‘No.1 Yongfeng’ chestnut in Yongren county，Yunnan，using semithin section method to comparative study its male gametophyte development.The results showed that the male gametophyte development of ‘No.1 Yongfeng’ was slower in early and faster in later.The male gametophyte development of ‘Yanlong’ was just the opposite.And the male gametophyte development of ‘No.1 Yongfeng’ chestnut was about nine days earlier than ‘Yanlong’.Their male gametophyte development took about 32 days from the beginning to the end.Both of them had four microsporanges.The type of tapetum was glandular tapetum.The development of anther wall was basic type and the shape of pollen was prolate spheroids.
