摘要

Cressa cretica L.是一种单型植物,属于植物科旋花科,cresaceae族。它是一种直立的小矮灌木,通常生长在沿海地区,被认为是一种重要的药用植物,具有许多治疗作用。这个物种的个体在埃及的特定地区受到限制,并受到灭绝的威胁。本研究除了花粉粒形态外,还仔细检查了叶片的外部和内部结构。该研究旨在了解该物种的形态特征,并保护其免受本地化和破坏过程的影响。结果表明:叶的大微形态特征为盐生叶,单细胞毛长,毛呈t形,气孔凹陷;叶片内部叶肉分化为单层栅栏和海绵状层,叶肉中分布着丰富的草酸钙晶体和盐腺。花粉粒产量少,体积小,球型至近长形,有三孔孔,有盖上孔。结果表明,Cressa cretica除了少量的小花粉粒外,还具有内外盐生结构。为了保护该植物,需要进行萌发试验来测试该植物在无盐生境下的花粉产量。

Systematic study in Cressa cretica L. (Convolvulaceae) species from Lake Qarun, El-Fayoum province, Egypt
Cressa cretica L. is a monotypic species belongs to the plant family Convolvulaceae, tribe Cresseae. It is an erect, small, dwarf shrub, commonly grown in coastal areas and considered as an important medicinal plant with many therapeutic effects. Individuals of this species became restricted in specific areas in Egypt in became under threat of extinction. This study dealt with careful examination of the external and leaf internal structure beside pollen grain morphology. The study aims to understand the species morphological characteristics and protect it from localization and destruction processes. The results showed that the leaf macro- and micro-morphological characters are of the halophytic ones, with long unicellular hairs as well as T-shaped hairs and sunken stomata. The leaf internal structure has mesophyll differentiated into one layer palisade and spongy layers full of ca-oxalate crystals and salt glands distributed in the mesophyll. Pollen grains productivity was few and they are small, spheroidal to subprolate with tricolporate aperture and tectate perforate with supra-tectum granules. The results obtained show that Cressa cretica has external and internal halophytic structure in addition to few small pollen grains. Germination experiments needed to test the pollen productivity of this plant under non-saline habitats for its conservation.
