桑树的冬芽培养,国外曾诱导出试管植株,但未见有移栽的报导。国内仅见有吉林省蚕研所的实生苗的芽培养及中国科学院森林土壤研究所的桑树茎段离体培养的报导。本试验以成龄桑树的冬芽作为外植体,目的在于探讨利用组织培养方法,培育良种桑苗的技术。现已从火桑、剑持、藤桑等7个品种中诱导出了完整的植株,并移栽成活,见照片(封底)。兹将研究结果报道于下。一、材料与方法(一)于早春桑芽萌发之前,从19年生的桑树上剪取一年生枝条的中、上部份,以塑 Winter mulberry bud culture, test tube plants have been induced in foreign countries, but no transplanting reported. In China, only buds of shoots of seedlings of Jilin Silkworm Research Institute and in vitro culture of mulberry stems of Institute of Forest Soil Science, Chinese Academy of Sciences were reported. In this experiment, adult buds of winter mulberry as explants, the purpose is to explore the use of tissue culture methods to cultivate seedling mulberry technology. Has been from the fire Sang, sword holding, rattan mulberry and other seven varieties in the induction of a complete plant, and transplanted to survive, see photos (back cover). The results will be reported below. First, materials and methods (A) Before the early spring mulberry germination, mulberry from the 19-year-old branches cut the annual and upper part of the plastic
