摘要
空心瓜为一年生葫芦科植物,可能起源于印度西北部,主要在印度、巴基斯坦、阿富汗和东非等地作为蔬菜作物种植,我国尚未进行栽培推广。长期以来空心瓜的系统分类不甚清楚,虽然总体形态与西瓜属植物相似,并具有甜瓜属植物染色体2n=24的数量特征,但多年研究结果表明,空心瓜并不属于西瓜属或甜瓜属植物。最新研究发现,空心瓜与冬瓜具有较近的亲缘关系,表明空心瓜很可能为冬瓜属植物,结合多年观察结果分析,本文提出将空心瓜归于冬瓜属的一个种,以供探讨。
Praecitrullus fistulosus(Stocks)Pangalo is annual cucurbitaceae plant and it is probably originated from north-western India.It is cultivated as a vegetable crop in India,Pakistan,Afghanistan,and East Africa,etc.It has not been cultivated and extended in China.The taxonomic classification of Praecitrullus fistulosus(Stocks)Pangalo is unclear for a long time,though its gross morphological features are seemly similar to watermelon.It has the same chromosome numbers(2n=24)as Cucumis melon.Many years'research results showed that Praecitrullus fistulosus(Stocks)Pangalo did not belong to Citrullus ssp.or Cucumis ssp.The latest research results showed that Praecitrullus fistulosus(Stocks)Pangalo had closer relationship with Benincasa hispida and it may belong to Benincasa ssp.With many years analysis and botany observation on Praecitrullus fistulosus(Stocks)Pangalo,we suggest that it be classified with Benincasa ssp.
