【摘要】 本文从解剖学和生理学的角度,对龙眼假种皮的发生和果实的个体发育进行了进一步的研究。观察结果认为,龙眼果实的个体发育可分为两个阶段,第1期是果皮和种皮生长期,约50天左右;第2期是假种皮,子叶生长及果实成熟期,约60天左右。果皮和种皮的明显生长在前,且几乎是同步的;假种皮明显生长在后。更多还原

【Abstract】 A further study on the aril initiation and ontogenesis of Longan fruit from the angles of anatomy and physiology was carried out. The ontogenesis of Longan fruit maybe divided into two different stages based on the examination. The first stage is the growth of fruit and seed coats, about 50 days. The second stage is the growth of aril and cotyledon, and fruit maturing. Its duration is about 60 days. Obviously, the growth of fruit and seed coats is almost synchronism and takes place before the growth of cotyledon and aril.更多还原
