[目的]研究油桐芽苗砧嫁接繁育新技术,建立油桐芽苗砧嫁接无性繁殖技术体系,为油桐良种无性化育苗提供新途径.[方法]以千年桐和三年桐种子培育的芽苗为砧木,以'华桐 1号'家系当年生半木质化带芽茎段为接穗,连续 2年研究不同砧木物种、嫁接方法、嫁接膜类型、嫁接时期、苗床及移栽高度等因素对油桐芽苗砧嫁接成活的影响,并观察嫁接后伤口愈合的显微解剖结构.[结果]1)在其他外界因素较优的条件下,以三年桐和千年桐为砧木,油桐嫁接成活率均可达 89.0%以上,前期生长无显著差异.以千年桐为砧木,采用劈接法用塑料膜绑扎的成活率比铝箔片高 184.0%,差异显著(P

[Objective]Tung tree is one of the four major woody oil tree species in China.The development of tung tree industry has certain strategic significance for improving China's energy self-sufficiency.This paper aims to establish a new asexual reproduction technology system for tung tree seedlings with hypocotyle rootstocks grafting by studying the new technique of tung tree seedlings and hypocotyle grafting,so as to provide a new way for the future asexual reproduction of tung tree elite varieties.[Method]The seedlings cultivated from Vernicia montana and Vernicia fordii seeds were used as rootst...
