| 摘 要： | 先将毛泡桐叶片在MS,WPM,KM_8P和B_5等液体基本培养基中进行悬浮培养,然后建立毛泡桐叶片悬浮细胞培养及其体外植株再生体系.结果表明,毛泡桐叶片愈伤组织悬浮诱导最适培养基为改良MS+0.2 mg·L~(-1) NAA+8 mg·L~(-1)BA;细胞悬浮培养的最佳起始密度为6.67×10~6个·mL~(-1);悬浮愈伤组织芽诱导和根诱导的最适培养基分别为MS+0.3 mg·L~(-1)NAA+17 mg·L~(-1)BA和1/2MS+0.1 mg·L~(-1)NAA.

| Abstract: | The suspension cell line and system of its in vitro plantlet regeneration from the leaves of Paulownia tomentosa were established through optimization of the mineral and organic substances in MS media supplemented with various NAA and BA concentrations on the basis of callus induction rates in the basal liquid MS,WPM,KM8P and Bs.The results indicated that the optimal medium of callus in-duction from the leaves of Paulownia tomentosa were modified liquid MS +0.2 mg · L~(-1)NAA +8 mg·L~(-1) BA; and the best primary density for the cell culture was 6.67 × 10~6; The optimal ones of shoot and root induction from the induced calli in the modified liquid MS media were MS +0.3 mg · L~(-1) NAA + 17 mg · L~(-1)BA and 1/2MS +0.1 mg · L~(-1)NAA,respectively. |
