从梨刺茎段培养直接诱导了不定芽,并形成了完整的试管苗.试验表明,在MS+ZT 1.75 mg·L-1+KT 2.0 mg·L-1培养基中,梨枣茎段可以分化不定芽,低含量的NAA和AgNO3可以促进不定芽的形成.在MS+ZT 1.75mg·L-1+KT 2.0 mg·L-1+NAA 0.05 mg·L-1+AgNO3 2.0 mg·L-1培养基中,芽的增殖系数最高,达到2.25倍.在1/2MS+IBA 0.08 mg·L-1培养基上.试管苗的生根率达到95.0%.

Adventitious shoot was induced from the stem fragment of pear, and forms a complete vitro-seedling. The test indicated that the stem fragment of pear jujube can differentiate adventitious shoot in the medium composed of MS, ZT(1.75 mg·L~(-1)) and KT(2.0 mg·L~(-1)), and lower content of NAA and AgNO3 can promote the formation of adventitious shoot. In the medium composed of MS, ZT(1.75 mg·L~(-1)), KT(2.0 mg·L~(-1)), NAA(0.05 (mg·L~(-1))) and AgNO3(2.0 mg·L~(-1)), the propagating coefficient of shoot is the highest which is 2.25 times a...
