【摘要】研究了不同浓度的镧离子对银杏幼叶愈伤组织生长的影响 ,发现加入 10 -4 g/L ,10 -3 g/L ,10 -2 g/L ,10 -1g/L镧离子培养基上的愈伤组织生长速度均优于对照 ,其中 10 -4 g/L的浓度最佳 ,和继代培养的结果是一致的更多还原

【Abstract】 Various concentrations of La 3+ are added to media to culture the callus of Ginkgo biloba L . The growth ratios of callus containing La 3+ of 10 -4 g/L,10 -3 g/L,10 -2 g/L, 10 -1 g/L are superior to that of control, and 10 -4 g/L is the most adaptive concentration. The similar results have been gained in the subculture.更多还原
