砧木对接穗的影响,果树方面,国内外做了大量的研究.一般认为,砧木对接穗的生长、产量和抗性等均有不同程度和不同性质的影响.在巴西橡胶方面,东南亚国家的橡胶研究院(所)曾就“砧木对接穗的影响”及“接穗和砧木的亲合性”等问题作了研究.如马来亚橡胶研究院的试验结果认为,用高产无性系实生苗作砧木比用低产无性系实生苗作砧木,能使同一无性系增产13—20%.印尼的试验结果表明用经选无性系实生苗作砧木,比用未经选的实生苗作砧木,其芽接树的产量高达30%;而南越橡胶研究所试验认为:不同砧木品系的植株,胶乳乳洁的磷、镁随着不同的砧木品系而有显著的差异.据东南亚产胶国的估计,用未经选择的实生苗作砧木,其芽接材的产量损失达15—40%之间.
Rootstock on the scion, fruit trees, made a lot of research at home and abroad.It is generally believed that the rootstocks scion growth, yield and resistance, etc. have different degrees and different nature of the impact.In Brazil rubber, Southeast Asian countries rubber Institute (Institute) on the “impact of scion on scion” and “scion and rootstock affinity” and other issues such as the Malayan Institute of rubber test results that the high yield clone as a rootstock Than the use of low-yield clones of seedlings as rootstocks, the same clones can yield 13-20% .In Indonesia test results show that the use of selected clonal seedlings as rootstocks, compared with the use of non-selected seedlings as rootstock, its budding tree Of the yield of up to 30%; and South Vietnam Rubber Institute test that: different rootstock strains, latex milk phosphorus, magnesium milk with different rootstock strains have significant differences.According to the Southeast Asian countries are estimated to glue countries, with no The selected seedlings for rootstocks, the budding material yield loss of between 15-40%.
