荞麦是禾本科之外的谷物类作物,具有较高的营养和药用价值。栽培荞麦有甜荞(Fagopyrum esculentum)和苦荞(F. tartaricum),这两种一年生草本分别为自交不亲和的二型花柱、自交亲和的同型花柱植物;前者结实依赖昆虫传粉。根据国内外调查研究,前人对蓼科荞麦属(Fagopyrum)记录了30个物种名,已有形态学和遗传多样性的调查表明该属的物种多样性中心位于我国西南地区,特别是长江上游的三江并流区域;甜荞和苦荞的起源地和祖先物种也认为在该区域。本文在论述前人研究的基础上,指出对荞麦属的分类修订、野生种质资源的分布、种间关系的调查、优良品种的选育亟待研究。孢粉学和考古学的证据显示在我国长...

Buckwheat is a pseudo-cereal with high nutritional and officinal value, a food crop outside of Poaceae. Cultivated buckwheat includes two species: sweet or common buckwheat (Fagopyrum esculentum), a self-incompatible, distylous annual and bitter or tartary buckwheat (F. tartaricum), a self-compatible, homostylous annual herb; the former depends on insect pollination for seed production. Thirty species have been named in the genus Fagopyrum (Polygonaceae) in the world. Investigations of morphology and genetic diversity suggest that Southwest Chi...
