摘要
Cell cultures obtained from Vitis vinifera cvs Michele Palieri and Red Globe were cultured in order to stimulate stilbene production. In the calli, stilbene production peaked at day 22 of culture for both cultivars; the main compound was trans-piceid, followed by cis-piceid. Methyl jasmonate, which was added to cell suspensions in the first half of the exponential growth phase, enhanced stilbene accumulation, producing mainly trans-piceid and ε-viniferin. Other stilbenoids, though in lower quantities, were identified by liquid chromatography/positive electrospray mass spectrometry. ε-Viniferin and trans-resveratrol were the main compounds released into the culture medium. The total quantity of stilbenes was genotype dependent, with a better response found for the cv Red Globe.
