| Abstract:
Aspects of vegetative and reproductive growth of mango cv Kensington growing in a marginal area (7.4° and 19.6°C min. and max. temperatures for winter) were studied for two growth seasons. Observations showed that vegetative growth occurred only during the period in which mean monthly temperature rose above 15°C while inflorescences emerged during the period in which a mean monthly temperature was between 12° to 17°C. The probability of flowering of a terminal shoot was related to whether that shoot had undergone a period of vegetative growth in the season before flowering. The percentage of fruit set was also affected by the vigour of individual shoots as measured by the number of vegetative flushes (nil to three) in the season before flowering. Subsequent vegetative growth was influenced by the current crop load and the vigour of shoots as measured by the number of vegetative flushes (one to three) in their last growth season. The number of terminal shoots in the canopy rose gradually as the trees aged, however the proportion of new shoots (shoots with one or more flushes in the current season) decreased. The manipulation of growth and yield for mangoes in a marginal climates were discussed. | |
