Effect of Triacontanol on Plant Cell Cultures in Vitro

Abstract
Triacontanol CH3(CH2)28CH2OH [Medicago sativa] increased growth in vitro of cell cultures of haploid tobacco (Nicotiana tabacum). The fresh weight of cell cultures of tomato (Lycopersicon esculentum), potato (Solanum tuberosum), bean (Phaseolus vulgaris) and barley (Hordeum vulgare .times. H. jubatum) was also increased. The increase in growth of tobacco callus may be due to an increase in cell number. Another long chain alcohol, octocosanol CH3(CH2)26CH2OH , did not increase the growth of tobacco cell cultures.
