摘　　要：蓖麻为异花受粉作物,雌雄同株异花,但有时可发现雄性不育蓖麻植株,即在植株花序上只有雌花,没有雄花,不能进行正常繁殖。使蓖麻在杂优利用上一直受到很大限制。通过对蓖麻雌性单株不同年龄枝条高空压接技术研究,从生根百分率、每枝平均生根数、最长根长、平均根长4个方面,研究高空压接的繁殖效果。在保持蓖麻本身的不育特性的前提下,避开寻找保持系进行繁殖,为进行杂优利用奠定基础。Castor (Ricinus communis) is monoecism crop with few pistillate plants without male flowers which couldnet propagate, and could not be asedin hybrid seed produetion. The marcottage of different ages wattle from pistillate plants of Castor (Ricinus communis) was studied in percent of rooting, the number of root per plant, length of longest root, and average length of root. The pistillate plants were propagated without maintainer lines in marcotlage wany, and maintaine male sterility, which can be used in hybrid seed production.
