The possible role of abscisic acid-like and other inhibitors in cherelle wilt of cocoa (Theobroma cacao L.)
The endogenous growth promoters and inhibitors at different stages of healthy and wilting "ICS 1" cocoa pods were determined using oat coleoptile straight growth bioassay. ABA-like substances were found in healthy as well as wilting pods. Wilting pods contained high level of ABA-like substances than healthy pods of corresponding growth stages. A high level of ABA-like substance was recorded in the first seven weeks of pod growth - a period during which the cherelles were highly susceptible to wilt, while very low levels of such inhibitors were present during subsequent stages of pod growth, which, however, increased at maturity. The growth promoter activity in wilting pods was much less than in healthy pods of corresponding stages of growth. Abscisic acid-like substances was maximum (8,75 micra g/g) during second week from fruit set in wilting pods. Hence, it is reasonable to believe that high ABA content is associated with cherelle wilt in cocoa
