以１３个苹果品种、砧木为试材，采用热处理和茎尖培养相结合的方法脱除病毒。结果表明：Ｍ４及国光的脱病毒效果最好，热处理３０天以上，脱毒率为８３．３％；金矮生和长富２号经２１天热处理，脱毒率也可达８０％；北斗和新乔纳金的脱毒率稍低，但也比传统热处理绿枝接高３６．７％和３０．０％。另外，各试材热处理后的死苗率和死苗高峰期有较大差异，而且茎尖培养绿枝芽的分化反应也不同。 Thirteen varieties of apple and rootstock were used as test materials, and the virus was removed by a combination of heat treatment and shoot tip culture. The results showed that: M4 and Guoguang had the best virus-free effect, the heat-treated for more than 30 days, the detoxification rate was 83.3%; Jinfuan and Changfu-2 were 21 days heat-treated, The virginity rate was slightly lower with neo-Jonathan, but also 36.7% and 30.0% higher than the traditional heat-treated green shoots. In addition, the rate of dead seedling after heat-treatment of each test material is quite different from the peak of dead seedling, and the differentiation reaction of green shoots is also different.
