摘要
以澳洲坚果品种A16枝条为接穗,使用合接法进行嫁接,探索澳洲坚果砧木叶片对嫁接成活率及苗木品质的影响。结果表明,砧木保留2片叶和保留全部叶片与砧木不留叶片之间的嫁接成活率达显著差异(P<0.05),砧木保留2片叶嫁接成活率比相对保留全部叶片的要高,但差异不显著(P>0.05),嫁接砧木留叶能有效提升嫁接成活率,而适当减少砧木叶片不影响嫁接成活率。砧木叶片数量的增加或减少对接穗生长表现出有促进或抑制的作用,砧木叶片减少对接穗有促进分枝的作用趋势。
Take cultivar A16 shoots as scion,graft experiment with macadamia rootstock was conducted to study the effect of retaining leaves on survival rate and seedling quality by using splicing method.The results showed that there were significant difference(P<0.05)in survival rate among three treatments.Of which the higher survival rate can be gained in treatment 1(with two retained leaves)and treatment 3(control),while the lower one in treatment 2(bare).There is no significant difference(P>0.05)in treatment 1 and treatment 3,even though treatment 1 has a little higher survival rate than that of in treatment 3.It`s found that survival rate can be improved greatly while retained some leaves on rootstock,but there is also no effect on survival rate after picking off leaves appropriately.The more or less number of leaves may promote or inhibit the growth of the scion,the decrease of leaf number on rootstock has a promoting effect on scion branching.
