目的:培育天麻的珍稀品种绿天麻。方法:结果:自交培育的绿天麻植株高1～1.5 m,花茎蓝绿或青绿色、黄绿色,花绿色或黄绿色,果卵圆形绿色。球茎圆锥形,呈略弯曲和直立2种形态,最大重量约800 g,折干率21.33%左右,天麻素含量高达0.71%。种子发芽率及繁殖率均高,干品天麻含有一种芳香型挥发油。结论:已将绿天麻经四代自交连续栽培纯化成农艺性状稳定的新品种。 Objective: To cultivate the rare species of Gastrodia elata. Methods: Results: The plants of self-fertilized plants were 1 ~ 1.5 m in height. The stems were blue-green or turquoise, yellow-green, green-yellow or yellow-green. Bulbous conical, slightly curved and upright two kinds of morphology, the maximum weight of about 800 g, drying rate of about 21.33%, gastrodin content of up to 0.71%. Seed germination rate and reproductive rate are high, dry gastrodia contains an aromatic volatile oil. CONCLUSION: Four-generation self-fertilizing continuous cultivation of N. pumila has been purified to a new agronomic trait.
