摘要/Abstract

摘要：

对蓝钟花属（Cyananthus）11种植物的种子在体视显微镜和扫描电镜下的外部形态、内部结构以及微形态特征进行研究。结果表明：蓝钟花属种子呈窄卵形，表面光滑，颜色多为黑色、褐色至棕色，其中多年生组表面具有特殊黑色斑纹；胚属短小型，胚乳白色或棕色，胶质或脂质；种皮表面纹饰为条纹型，网壁螺旋排列或平行排列，又可细分为阔网状条纹、窄网状条纹与一般性条纹三种类型。种子形态在属下三组间差异明显，种子长度、表面颜色及表面纹饰为属内组的划分提供了重要依据。此外，一年生组各种在种子形态上分化最为明显，可能与其较强的适应性有关。

Abstract:

Morphological characteristics of seeds (external, interior and seedcoat) in 11 species of Cyananthus were examined under stereomicroscope and scanning electron microscopy (SEM). The results indicate that seeds of Cyananthus are narrowly ovoid in shape, episperm are black, tan or brown and smooth. The episperm of sect. Stenolobi has a special black seed mottling. Embry of the seeds belongs to dwarf type, with white or brown, colloidal or oily endosperm. Ornamentation of seed coat belongs to striate type, ribs arranged spirally or parallel, and could further be divided into three types, as broadly reticulatestriate, narrowly reticulatestriate and striate. The seed morphology varies apparently among the three sections within the genus. The characters of seeds, such the length, the color on the surface and the ornamentation on seed coat, are of great significance in distinguishing the three sections of Cyananthus. Besides, sect. Annui demonstrated the highest level of diversification in seed morphology, which may be correlated to the more advanced adaptation of this section.
