【摘要】 目的:研究独一味在低海拔移栽地的结实率。方法:将独一味根茎芽从海拔4 300 m的野生地移栽到海拔为2 366m和3 100 m的多巴及大通实验基地,研究其在移栽地的花粉活力,花粉在柱头上的萌发及自然结实率。结果:独一味在移栽地花粉活力较低,柱头上没有花粉及花粉管的萌发,在栽培地的自然结实率为0。结论:独一味在移栽地传粉效率和结实率都较低。更多还原

【Abstract】 Objective:To study the seed-setting rate of Lamiophlomis rotata(Benth.)Kudo from high altitude to low altitude.Methods:The effects of pollen vitality,pollen germination in the stigma and seed-setting rate when the rhizome bud of Lamiophlomis rotata(Benth.)Kudo were transplanted from an altitude of 4 300 meters to altitude of 2 366 meters and 3 100 meters of Duoba and Datong experimental station.Results:In the cultivation,the pollen vitality of Lamiophlomis rotata is low,the pollen tube not germination in stigma and the seed-setting rate is 0.Conclusion:Lamiophlomis rotata’s pollination efficiency and seed-setting rate are low in the cultivation.更多还原
