摘要
一种原产墨西哥的提取薯蓣皂甙元(diosgenin)的重要原料植物菊叶薯蓣(Dioscorea composite Hemsl.),首次在我国西双版纳引种成功。试验结果表明,种子萌发以35℃最为适宜。种子千粒重达9克者,发芽率最高,可达90％以上。种子贮存期在3—4个月内,发芽率高而整齐。播种60天藤蔓开始有缠绕能力,可以移栽。移栽后12个月出现花蕾,开花结果。每年两次花果期。营养生长与生殖生长交叉进行。叶终年常绿。块茎常年生长,产量逐年增加。栽培三年最高亩产鲜块茎5494公斤(按单株测产)。粗皂甙元含量3—4％(干样)。粗皂甙元重结晶一次溶点203—206℃,有利用价值。
The cultured Dioscorea composite Hemsl. was introduced successfully by us from Mexico. This paper deals with the pattern of the growth and development of the plant in Xishuangbanna area, Yunnan province, China.The result shows the seed germination is related with tempereturc, thousandgraiu weight and the storage. The vine begins to grow quickly and the seedlings can be transplanted to field at sixty day after sowing. Flowing and fruiting in a year after transplant. The plant is evergreen, and has two flowing seasons in per year. The yield will be increasing year by year, because the tubers can grow continually. Our experiment shows that the highest yields reach up to 82410 kg/ha/yr, and the dio-sgenin content is 3-4% of the dry matter.
