【摘要】 黄果酸浆(Physalis alkekengi L.var.francheti Mast.)为茄科(Solanaceae)酸浆属(Physalis)多年生草本植物,因宿存膨大的花萼这种新颖结构,引起了人们对其的广泛关注。对酸浆不同发育时期的花萼进行形态学、表面微形态学和解剖学观察,结果表明:(1)在蕾期花萼生长较为明显,开花期间不再生长,而在果实发育期迅速膨大;(2)花蕾期花萼具表皮毛,但盛花期时完全退化;(3)发育过程中内外表皮细胞大小、形状均发生明显变化,但内外表皮特点有所不同;(4)萼片由表皮、叶肉、叶脉三部分组成,叶肉更倾向于海绵组织的特点,主脉发达,具双韧维管束。本文观察其花萼发育的动态过程,为花器官发育的分子机制研究提供形态解剖学依据。更多还原

【Abstract】 As a perennial herbaceous plant in Solanaceae Physalis,Physalis alkekengi L. var. francheti Mast. caused widespread attention due to its novel structure"persistent calyx". Morphological,micro-morphological and anatomical features were observed. The results showed:( 1) The growth of calyx was obvious during bud stage. The growth of calyx is very limited during the flowering period.But it had a rapid growth during the fruit development;( 2) There were many epidermis hairs in the calyx during bud stage,but they degraded completely during the flowering period;( 3) During the development period,the size and shape of internal and external epidermal cells changed obviously,but the characteristics of the internal and external epidermal were different;( 4) The sepals consists of epidermis,mesophyll,and vein. The mesophyll tends to have the properties of spongy tissue. Its main vein with bicollateral vascular bundle was very developed.更多还原
