ABSTRACT

Objective:

To study the effect of different hormone ratios on the callus induction of roots,stems and leaves of Polygala tenuifolia,and determine and analyze the amount of flavonoids in roots,stems and leaves of P. tenuifolia.

Method:

With MS as the basic medium and roots,stems and leaves of P. tenuifolia sterile seedings as explants,the effects of 2,4-D,NAA and 6-BA on callus induction and flavonoid accumulation in different parts of roots,stems and leaves of P. tenuifolia were determined by orthogonal test.

Result:

2,4-D,NAA and 6-BA had significant effects on the callus induction rate of roots,stems and leaves of P. tenuifolia. The optimal callus induction combination of leaves was MS+3.0 mg·L-1 2,4-D+1.0 mg·L-1 NAA+1.5 mg·L-1 6-BA,the optimal callus induction combination of stems was MS+1.0 mg·L-1 2,4-D+3.0 mg·L-1 NAA+1.5 mg·L-1 6-BA,the optimal callus induction combination for roots was MS+1.0 mg·L-1 2,4-D+1.0 mg·L-1 NAA+1.0 mg·L-1 6-BA. And 2,4-D,NAA and 6-BA had significant effects on flavonoid accumulation in the stem callus of P. tenuifolia,and MS+3.0 mg·L-1 2,4-D+1.0 mg·L-1 NAA+0.5 mg·L-1 6-BA was the best flavonoid accumulation combination.NAA,6-BA had significant effects on flavonoid accumulation in the leave callus of P. tenuifolia,while 2,4-D had no significant effect,and MS+3.0 mg·L-1 2,4-D+2.0 mg·L-1 NAA+1.0 mg·L-1 6-BA was the optimal flavonoid accumulation combination,the three hormones had no significant effect on the accumulation of flavonoids in the root callus of P. tenuifolia,and MS+2.0 mg·L-1 2,4-D+1.0 mg·L-1 NAA+1.5 mg·L-1 6-BA was the best flavonoid accumulation combination.

Conclusion:

Under the conditions,the callus induction rate of roots,stems and leaves of P. tenuifolia is 100%, especially, the callus of P. tenuifolia leaves was the optimal,which is followed by P. tenuifolia stems and P. tenuifolia roots. Under the conditions,the amount of flavonoids in roots,stems and leaves of P. tenuifolia reach 21.31,24.56,23.61 mg·g-1,respectively.
