    摘要:

    为探讨高粱属(Sorghum Moench)的系统发育关系,通过野外调查及查阅标本和文献资料,对高粱属植物的地理分布进行了整理和研究。高粱属植物约有29 种,分布于全世界热带到温带地区,其中澳大利亚22 种,亚洲15 种,非洲9 种,欧洲3 种,地中海2 种,美洲6 种。中国有5 种,分布在东北、西南到华南各省(区)。高粱属有5 亚属,仅高粱亚属(subgen. Sorghum)延伸至新世界,其他亚属均分布在旧世界,高粱亚属覆盖非洲并扩散到全世界热带到温带地区;拟高粱亚属(subgen. Parasorghum)分布在非洲、亚洲、澳大利亚;有柄高粱亚属(subgen. Stiposorghum)主要分布在澳大利亚,个别种分布到亚洲;多毛高粱亚属(subgen. Chaetosorghum)分布在澳大利亚;异高粱亚属(subgen. Heterosorghum)分布在澳大利亚和亚洲。这表明澳大利亚东北部是高粱属的现代分布中心和多样化中心,非洲东北部和热带亚洲是否是高粱属的起源地尚需确证。

    Abstract:

    In order to accumulate data for the phylogenetic reconstruction of Sorghum, the geographical distribution of Sorghum Moench (Andropogoneae, Panicoideae, Poaceae) was studied by field investigation and reviewing specimen and literature. Sorghum, including about 29 species, is a representative group in the tribe Andropogoneae due to the paired heterogamous spikelets (one sessile, fertile; the other one pedicelled, staminate or sterile) made up racemes along each node of inflorescences. Sorghum species distribute in the tropical and subtropical to temperate regions, with the species number being 22, 15, 9, 3, 2 in Australia, Asia, Africa, Europe, and Mediterranean, respectively. In addition, six species have extended to the Americas. In China, five species distribute in northeastern, southwestern, and southern provinces. Among five subgenera of Sorghum, only subgen. Sorghum has representatives in the New World, other subgenera are restricted to the Old World. The subgen. Sorghum presents in Africa then spread to tropical and temperate regions around the world, subgen. Parasorghum extends from Africa, Asia to Australia, subgen. Stiposorghum occurrs in Australia and Asia, subgen. Chaetosorghum is found in Australia, and subgen. Heterosorghum is found in Australia and Aisa. These results suggested that northeast Australia was the distribution center and diversification center of Sorghum, while the origin center of Sorghum needs to be further studied.
