【摘要】 以金花梨试管苗叶片为试验材料,每叶片横切三刀,培养在NN69培养基上,先暗培养三周再转自光下,实验表明:NN69+细胞分裂素5.0 mg/l(BA2.5+KT1.25+ZT1.25)+IBA0.3mg/l为诱导叶片产生不定梢的最佳培养基配方。更多还原

【Abstract】 Young leaves in vitro of pear cultivars were selected as materials.Results showed that higher regenewere rate accounted for 87.25% when turned on the medium with NN69+cytokinin 5.0 mg/l(BA2.5+KT1.25+ZT1.25)+IBA0.3mg/l+sucrose 5.5% in the dark for three weeks,then expose to light.更多还原
