马铃薯脱毒试管苗二次结薯的产量试验

Yield of Second Harvest of Potato Tuber from Transplanted in vitro Plantlets in Net House

为解决生产中存在的马铃薯脱毒试管苗生产成本高、生产微型薯繁殖系数低、造成微型薯价格居高不下的难题,本研究选用两个马铃薯品种(抗疫白和润者),在防虫温室收获完微型薯后,把植株再移栽到网棚,株行距20 cm×60 cm,继续使其结薯,进行二次收获。结果其产量远高于第一次收获生产微型薯的产量,因此大大提高了种薯生产效率。

Plantlets in vitro of two potato varieties,Kennebec and Ranger,were transplanted into a insect-proof greenhouse to produce minitubers,and the potato plants after harvest of the minitubers were then replanted 20 cm within a row and 60 cm between rows in a net house for second harvest in order to solve the problem of high cost of minituber production due to the low propagation coefficient.The results indicated that the yield of second harvest was higher that the first one,therefore increasing the production efficiency.
