变温变湿处理促进人参种子后熟

Alternating Temperature and Moisture Accelerate Ginseng Embryonic After-ripening

人参(Panax ginseng C.A.Meyer)在我省引种栽培虽已取得突破性进展,但因生产周期长,尤其是在夏秋季直接播种,种胚需要经历18—22个月的后熟过程,使许多人参种植者不能促进种子后熟而导致种植失败。本试验根据青海气候特点,从温度、湿度、处理时间及胚的发育等方面,研究了促进人参种子后熟的方法。提出了在我省夏秋季采用阶段性变温、变湿及适当时间处理促进人参种子形态后熟和冬季低温处理促进生理后熟的具体要求。

Introduction and cultivation of Ginseng had made a great pr-ogress in Qing Hai. But the cultivation by direct seeding in summer or autumn required 18-22months in the field for embryo to finish morphologic after-ripening, broughtabout the failure that many planters could not acce-lerate it. According to Qing Hai climate condition, the experiment studied embryonic development and the method about accelerating the emhryonic after-ripening at temperature , moisture and different length of time , put forward concrete demands on stage alternating temperature、moisture and different length of time treatment for accelernting embryonic morphologic after-ripening in summer and autumn or accelerating embryonic physiologic after-ripening in Winter Qing Hai.
