摘    要:通过对樱椒树(TapisciasinensisOliv)开花结果过程的连续观察和部分阶段的切片观察,在本文首次报道了樱椒树的开花结果过程。樱椒树6—7月开花,从9月起幼果进入休眠期,直至来年4月,幼果重新萌动,继续发育.到9月果实成熟;其从开花到果实成熟共需15个多月。通过切片观察初步确定合子在经过1或2次分裂后,即停止分裂,只有顶细胞越过休眠期,发育成胚,其余细胞均在停止分裂之后便逐渐解体,到休眠期时即看不到。其花托非常发达,在花期后期长大,并在周围下延,包围很短的花柄,到开花当年9月初即完全包围花柄。

关 键 词:樱椒树    果实  花托  合子

Abstract:Through continuous observation on the develapmentd process of the flowering and fruiting of T. sinensis Oliv.,and its sections of several stage of flower and fruit,in this paper,we have primary reported a complete developmental process of the flowering and fruiting of T. sinersis florescens from June to July; since september,the young fruit has enterd the resting period ; the April of next year,the young fruit starts growth again,then it develop to a mature fnuit at september. This process takes more then 15 months. Through observation of the sections of flower and fruit, it primaryly be thought that zygote first has divided one or two, then stopped dividing and the terminal cell live to mext year,and develop to. a mature embryo,the other cells couldn't be seen in resting period. its torns is very big,in the end of flowering period,it grows quickly and the edge grows toward the base of pedicel and closes the short pedicel, untilthe initial stadge of september,it completly closes the short pedicel.
Keywords:Tapiscia sinensis Oliv  flower  fruif  torus  zygote
