摘要： 1986-1987年将金丝小枣高产质佳4个品系、成年树上的枣头茎段，使用MS基本培养基培养成试管苗。试验结果表明，外植体的生理状态与培养试管苗有直接关系；试管苗经常出现二次枝，它可以生根，但生芽继代繁殖困难；利用果仁接种在适宜培养基上，可以生长健壮植株，下胚轴可由不定芽发育成小植株。

Abstract: From 1986 to 1987,we cultured the stems of adult trees of four strains,which are highly productive and quality,to test-tube plants by modified MS medium.The results showed there were direct relationships between the physiological status of explants and the test-tube plants;the test-tube plants offen developed second branches which could take root,but could'nt sprout;the plantlets were used to be grafted on a proper medium and could grow to robust plants and the advetltilious buds on hypocotyl could develop to young plants.
