摘要

Suaeda Forssk.其代表植物分布在整个中亚地区,通常生长在沿海卤叶植物群落中。在 40 种中亚物种中,哈萨克斯坦植物区系中有 18 种,其中 15 种(83%)分布在咸海-巴尔喀什地区。Suaeda 种类分布在 5 个部分(Schanginia C. A. Mey.、Lachnostigma Iljin、Conosperma Iljin、Physophora Iljin、Heterosperma Iljin)。研究的目的是分析咸海-巴尔喀什地区植物区系中 Suaeda 属物种种子的形态特征,该地区包括 5 个植物区系(14 - 咸海、15 - 基兹洛达、16 - 贝特帕克达拉、17 - 穆因库姆(莫因库姆)和 18 - 巴尔喀什-阿拉库尔)。在咸海-巴尔喀什地区发现的 15 个物种中,有 11 个物种的种子被用于形态特征比较分析(Suaeda linifolia Pall.、S. paradoxa Bunge、S. altissima (L.) Pall、S. dendroides (С. A. Mey.) Moq.、S. arcuata Bunge、S. acuminata (С. А. Меу.) Moq.、S. corniculata (С. А. Меу.) Bunge、S. heterophylla (Kar. et Kir.) Bunge、S. salsa (L.) Pall.、S. prostrata Pall.、S. crassifolia Pall.)。详细的研究显示了节间差异。在这方面,Suaeda acuminata 的种子与其他科的物种差异最为明显。Schanginia 部分的物种种子表面的颗粒结构基本相似,而 Heterosperma 部分的代表物种种子表面呈点状网格状,边缘扁平。

Features of the morphology of seeds of species of the genus Suaeda flora of the Aral-Balkhash region
Genus Suaeda Forssk. ex J. F. Gmel. is one of the largest in the family Chenopodiaceae Vent. (Amaranthaceae Juss.). Its representatives are distributed throughout Central Asia and are found, as a rule, in coastal halophyte communities. Out of 40 Central Asian species, there are 18 species in the flora of Kazakhstan, 15 (83 %) of which are found in the Aral-Balkhash region. Suaeda species are distributed in 5 sections (Schanginia C. A. Mey., Lachnostigma Iljin, Conosperma Iljin, Physophora Iljin, Heterosperma Iljin). The aim of the research was to analyze the features of the morphology of seeds of species of the genus Suaeda of the flora of the Aral-Balkhash region, which includes 5 floristic districts (14 - Aral, 15 -Kyzylorda, 16 - Betpakdala, 17 - Muyunkum (Moyinkum) and 18 - Balkhash-Alakul). Of the 15 species found within the Aral-Balkhash region, seeds of 11 species were taken for comparative analysis of morphological features (Suaeda linifolia Pall., S. paradoxa Bunge, S. altissima (L.) Pall., S. dendroides (С. A. Mey.) Moq., S. arcuata Bunge, S. acuminata (С. А. Меу.) Moq., S. corniculata (С. А. Меу.) Bunge, S. heterophylla (Kar. et Kir.) Bunge, S. salsa (L.) Pall., S. prostrata Pall., S. crassifolia Pall.). A detailed study reveals sectional differences. In this respect, the seeds of Suaeda acuminata differ most clearly from the species of other sections. from the Conosperma section. The species of the Schanginia section have a generally similar granular structure of the seed surface, and the representatives of the Heterosperma section have a point-grid surface of seeds with a flattened edge.
