种子植物假种皮研究综述

在查阅相关文献的基础上,综述了假种皮的概念、发育过程、形态特征、生物学意义,对我国具有假种皮的植物种类进行了统计.我国具有假种皮的植物约620种,以卫矛科最多,133种,占国产具假种皮植物种类的21%;其次是姜科,番荔枝科,鸭跖草科,远志科,杜英科等;具假种皮的植物有87%为热带区系成分;具有假种皮的木本植物种类约为草本的2倍;具假种皮植物的果实约有434种为裂果,占国产具假种皮植物种类的70%,其中蒴果所占比列最高,约370种.

Advances in Study on Aril of Spermatophyte

The concept of aril, developmental process, morphological characteristics and biological significance of the aril were summarized based on comprehensively consulting the related literature, and a statistics of species with aril in China was concluded. The statistics showed that there were about 620 arillate species in China. Family Celastraceae shared the most, with 133 species, accounting for 21% of the totality, followed by families of Zingiberaceae, Annonaceae, Commelinaceae, Polygalaceae, Elaeocarpaceae in turn. 87% of the all arillate species in China belonged to tropical floral elements. The number of woody arillate plants was 2 times as much as herbaceous. 434 species with dehiscent fruits accounted for 70% of the total aril plant species in China, among which capsular fruit plant species was the majority with 370 aril species.
