Abstract

This report demonstrates the elicitation effect on growth and stilbene accumulation in cell cultures of Cayratia trifolia (Vitaceae) by an extract of the angiosperm parasite Cuscuta reflexa and salicylic acid in combination with sucrose feeding. Cell cultures of C. trifolia, a tropical liana, were maintained in liquid Murashige and Skoog's basal medium containing 0.25 mg l−1 naphthalene acetic acid, 0.2 mg l−1 kinetin with 3% sucrose and 250 mg l−1 casein hydrolysate. The cells treated with Cuscuta elicitor showed increased polyphenol oxidase activity with increasing concentration of the elicitor, while total phenol content remained almost unchanged. Enhanced yield of stilbenes (∼8-fold) was recorded in the cells treated with 200 mg l−1Cuscuta elicitor for 7 d. Optimum accumulation of stilbenes with a non-significant decrease in cell growth as compared with control was recorded with the addition of 3% sucrose on the seventh day of cell culture. Addition of 3% sucrose with salicylic acid at 500 μM and Cuscuta extract at 200 mg l−1 on the seventh day enhanced total stilbene yield up to 50.1 mg l−1, which was ∼14-fold higher than in control cultures. Piceid content increased ∼200-fold in such cultures.
