| 摘 要： | 对培养基中影响杜仲愈伤组织胶合成的前体物质乙酸浓度进行了研究。结果表明,以S4代杜仲愈伤组织为原料,随着培养基中乙酸浓度的增加,杜仲愈伤组织中胶含量不断提高,但过高浓度的乙酸会抑制愈伤组织的生长;最适乙酸添加浓度为1.0~1.5 mm o l/L,此时,不会影响愈伤组织的生长,且其平均增长率为1 977.97%,其平均含胶量达原植株的81.20%,从而提高了杜仲愈伤组织的含胶量。

| Abstract: | Effects of acetic acid on the rubber content in the callus of Eucommia ulmoides by adding different amounts of the acid. The optimized concentrations of acetic acid were 1.0-1.5 mmol/L, which could not only enhance the growth of callus,but also increase the rubber content. Under this condition, the average growth rate of callus was 1 977.97% and the average rubber content of callus reached 81.20% of the original plant. Therefore, acetic acid can be added into the medium as a precursor to biosynthesize the rubber, so as to greatly increase the rubber content in callus. |
