The impact of panicle and shoot pruning on inflorescence and yield related developments in some mango cultivars.

Abstract

The effect of different kinds of pruning treatments was studied on Keitt and Tommy Atkins cultivars over two seasons. The trial was conducted at Bavaria Estate, around Hoedspruit area, Northern province of South Africa (latitude: 24o25'S; longitude: 30 54'E; elevation: 600m). With regard to inflorescence development, panicle pruning (during full bloom) at the point of apical bud attachment proved to induce re-flower, more rapid fruit development and more fruit per panicle than the other panicle pruning treatments. Renewal (early in the season when fruit were on the tree) as well as post harvest pruning (especially for early cultivars) treatments were also observed to effect a well-synchronized inflorescence development and adequate number of productive inflorescences per season. Post harvest pruning treatments produced a significantly higher result for the vegetative growth parameters in both cultivars while the control trees showed the lower result. Pertaining to yield, the trend showed that, promising increment could be expected after the second season (with vigilant management of the trees) especially from panicle pruning at apical bud attachment and shoot pruning treatments on 'Tommy Atkins'. 'Keitt' was found to be not responsive to the pruning treatments applied for various parameters observed.

Physiological age at harvest regulates the variability in postharvest ripening, sensory and nutritional characteristics of mango (Mangifera indica L.) cv. Coghshall due to growing conditions

“…It has also been clearly demonstrated that leaf/fruit ratio and water stress have an impact on the import of carbon assimilates in mango 5. Depending on the variety, tree management, including the pruning of specific shoots or the selection of inflorescences, can have an impact on firmness, sugar content and acidity in mango fruit 6…”

Recent Advances in Enhancing the Productivity of Mango (Mangifera indica L.) through Hi-tech Practices

“…But the productivity is very poor (7.3 MT/ha) when compared other mango producing countries due to use of poor planting material, traditional method of planting system, lack of awareness in training and pruning system, cultivation of alternate bearing varieties and poor orchard management (Balamohan and Gopu, 2014). Yeshitela et al, (2003) reveals that pruning at the point of apical bud attachment induced reflowering, more rapid fruit development and more fruits per panicle. Treatments such as pruning that manipulate timing of flush development and synchronize canopy flushing have been successful in increasing flowering intensity (Yeshitela et al, 2005).…”

Effect of De-blossoming Treatments on Physical Characteristics of Different Mango Varieties during Off-season Fruit Production under South Gujarat Conditions

“…This may be due to scarcity of photosynthates or higher utilization of soluble assimilates in regular season. Oosthuyse and Jacobs [13] and Yeshitela [14] found marginally higher fruit weight in hand de-blossomed treatments over untreated trees (control). [15] and Kaviarasu et al [16].…”
