ENVIRONMENTAL EFFECTS ON PHENOLOGY AND PHYSIOLOGY OF MANGO - A REVIEW
Recent research has demonstrated strong genotypic x environmental responses within and between the embryonic groups of mango cultivars which can largely account for their relative performance. More specifically, investigations in relation to the effects of low temperature and water deficit on floral induction in mango have been reported. From these there is common agreement that day/night temperatures below 20/15°C will result in floral induction. However, water deficit research with containerised mangoes has failed to induce flowering - a result inconsistent with opinion on floral induction mechanisms in the tropics.
Further evidence supporting cold temperatures during anthesis as a primary cause of the failure of fruit set in subtropical regions has been published and the results are discussed with respect to genotype performance.
