| Abstract:
Yield and fruit quality are two essential components of productivity. Yield is affected by certain known factors such as flowering, fruitset and retention whereas quality is influenced by a wide range of factors. For development of a common strategy for improvement of productivity, it is important to understand underlying mechanisms which regulate productivity. There are some important common factors such as tree vigour, nutrition, post bloom occurrence of vegetative flush which affect both yield and quality. Preponderance of flower-antagonistic and vegetative growth-promoting conditions in tropical conditions can severely curtail opportunities for mango growing. Based on the florigen and anti- florigen hypothesis, which propounds floral and vegetative cycles, a combination approach consisting of post harvest application of paclobutrazol and pre flower pruning has been developed for Kensington Pride mango for the tropical Top End of Australia. Besides inducing regular and increased flowering and fruiting, significant gains in quality especially external fruit appearance and firmness have been achieved with this approach which holds promise for higher density planting in tropics. | |
