Standardization of softwood grafting techniques in sapota (Manilkara achras L.) on invigorated khirni rootstock under polyhouse and shade net conditions

Abstract

Propagation studies in sapota with softwood grafting on invigorated khirni rootstocks were carried out with use of two length of scion (15 and 10 cm), under two propagation conditions (polyhouse and shade net) and in 4 different month of grafting (May, June, July and August). Growth of the grafted plant was recorded in 30 days intervals up to 120 days and there was increase in the growth parameters like number of leaves, height of the scion and number of sprouts per grafted plant had increased with the increase in days after grafting. In relevance to growth parameters like early sprouting, maximum number of leaves was recorded in grafts when they were made using 10 cm scion, propagated under polyhouse and grafted during the month of July. Maximum number of sprouts per grafted plant was observed in the month of May. The maximum growth in terms of height (above the union) were recorded in grafts made with use of 15 cm scion, propagated under polyhouse and grafted during the month of July.
