Studies on callus culture of Akebia trifoliata / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the inductive factors of effect on Akebia trifoliata and establish culture method for A. trifoliata callus.</p><p><b>METHOD</b>To study the possible effective factors of culture condition by comparing with different explantation, nutrient medium, pH, temperature, illumination, growth substance of plant and its ratio.</p><p><b>RESULT</b>The inductivity of leaves was the highest about 87.5%, followed with the stem section and leafstalk; The inductivity of nutrient medium such as MS, B5 callus was higher than the ones like H, SH and the White callus amended one; It was found that low-grade Phvalue benefits the growth of callus. The experiment result showed that different pH showed little difference in quality. The best condition of culture was 25 degrees C in temperature.</p><p><b>CONCLUSION</b>The best culture condition for callus was the leaves as explantation. The A. trifoliata callus culture's best inductive condition was MS +2, 4-D 4.0 mg x L(-1) + NAA 1.0 mg x L(-1) + KT 1.0 mg x L(-1) (pH 5.8), cultural temperature was 25 degrees C, cultivation was dark.</p>
