以引种的“燕龙”板栗和云南省永仁县本地“永丰1号”品种为试材,采用环氧树脂半薄切片法对二者的雄配子体发育进行了系统的比较研究,揭示了其生殖学进程和特点。结果表明:本地“永丰1号”板栗雄配子体发育早期较慢,后期较快,引种“燕龙”板栗恰恰相反;而且“永丰1号”板栗雄配子体发育比“燕龙”提前约9d。二者雄配子体发育从开始到结束整体用时相近,约32d;花药有4个花粉囊,两瓣、成对;绒毡层类型为腺质绒毡层;花药壁发育类型为基本型;花粉粒为长球型。
Using the introduced “Yanlong” chestnut and the “Yongfeng No.1” variety in Yongren county of Yunnan province as materials, we systematically compared the male gametophyte development of the two with the semi-thin epoxy resin method Research, reveal its reproductive process and characteristics. The results showed that the male gametophyte of local “Yongfeng 1” had a slower early development and a later rapid development, and the introduction of “Yanlong” chestnut was the opposite; and “Yongfeng No.1” “Yan Long ” about 9d in advance. Both male and female gametophyte development from the beginning to the end of the overall time-consuming, about 32d; anthers have four pollen sacs, two, in pairs; tapetum type glandular tapetum; anther wall type is basic; pollen grains For the long ball type.
