摘要:

中国有三种野生稻。野生稻是栽培水稻的野生近缘种,已被列为濒危植物[7],它们分布于中国南方8个省(区)的热带、亚热带湿热生境中。 近年来人为的干扰和生境的破坏已导致它们的居群大量绝灭,其中濒危程度最高的是普通野生稻。本文阐述了它们的生物学、生态学特性,研究了它们的群落学特征,初步报道了它们的濒危状况,探讨了致濒原因。

Abstract:

Abstract  There are three species of wild rice,which are wild relatives of the cultivated rice and listed in endangered plant species in China[7].They are distributed  in  humid  areas  of  tropical  and subtropical regions in eight provinces of southern  China. Recently,human disturbance and  destruction  of  habitats  have  led  to  the  extinction of a great number of populations,of which Oryza rufipogon Griff.  is  the  most  endangered  species.   In  this  paper,their  biological and ecological characteristics  were  described  and  the  plant communities were also studied.   Meanwhile, the  endangered status and the   reasons  of  wild rice  in  China were  discussed.
