Abstract
The influence of headspace ethylene on anthocyanin, anthocyanidin, and carotenoid accumulation was studied in suspension cultures of Vaccini um pahalae. Exogenous application of ethrel (an ethylene-releasing com pound) significantly reduced growth and secondary metabolite productio n, whereas incorporation of 5.0 or 10.0 mg l(-1) ClCl2 or NiCl2 effect ively reduced ethylene accumulation and improved product accumulation, but AgNO3 was toxic to cells. This study showed an overall negative i mpact of increased ethylene levels in the vessel headspace on phytoche mical production in ohelo cell cultures.
