目前,组织培养技术已在果树育种、繁殖等方面广泛应用。先后培育出试管苗的树种有苹果、桃、柑桔、葡萄、枣子、菠萝等。但试管苗移至露地栽培大批成功的还为数不多。如桃胚培技术可以培养出大量试管苗,而移栽到土中的成苗率却不高。近两年来,我们针对这一问题进行了研究,以探索死苗原因及其解决办法。
At present, tissue culture technology has been widely used in breeding and breeding fruit trees. Successively cultivated test-tube seedlings of apple, peach, orange, grape, dates, pineapple and so on. However, a large number of test-tube plantlets have been successfully cultivated in open-field cultivation. If peach embryo culture technology can produce a large number of in vitro seedlings, transplanting into the soil in the seedling rate is not high. In the past two years, we have conducted a study on this issue to explore the causes of dead seedlings and their solutions.
