Standardization of pruning severity for healthy bud production in 'Kinnow' (C. nobilis × C. deliciosa) mother plants
A study was undertaken to investigate the effect of pruning and its intensity on Kinnow mandarin (C. nobilis × C. deliciosa) plants reserved for taking bud wood with vigorous/excellent growth (G1) and plants with normal growth (G2). Shoot emergence was found earlier in pruned trees compared with unpruned trees. Pruning resulted in significantly higher vegetative growth in mother plants. Plants with excellent growth responded better to pruning than plants with normal growth. Severe pruning (5 feet) registered earliest shoot emergence, maximum number of buds per shoot. The number of shoots, shoot girth, seasonal availability of buds, plant height and spread were maximum in lightly pruned plants. Chlorophyll-a and chlorophyll-b contents were also recorded higher in pruned plants compared with unpruned plants. It was concluded that the Kinnow mother plants should be pruned at 8 feet above ground level during last week of January to first week of February to get regular and maximum bud production under subtropical conditions of northern plains of India.
