Veneer grafting and soft wood grafting techniques can be used for large scale multiplication of mango in north India.
The technique of softwood grafting is similar to that of cleft or wedge grafting. In this case, grafting is done on 3 month to 8 month old rootstocks. The rootstocks attain graftable thickness within 3-6 months due mild winter. In the past , this technique has been in use in situ orchard establishment under adverse soil and climatic conditions as the grafting operation is performed using cleft/wedge method on the newly grown top portion of the plant one year after the rootstock establishment in the field . The scion shoots of the thickness equal to that of rootstocks are defoliated 7-10 days prior to grafting. The graft should be secured firmly using 1.5 cm wide, 200-gauge polyethylene strip. July and August months with high humidity and moderate temperature are the best for the success of softwood grafting.
Veneer grafting :
This method of propagation holds promise for mass scale commercial propagation. The method is simple and can be adopted with success. Eight month to one year old seedling rootstocks are suitable for this method. For conducting this grafting operation, a downward and inward 3-4 cm long cut is made in the smooth area of the stock at a height of about 20 cm. At the base of cut, a small shorter cut is given to intersect the first so as to remove the piece of wood and bark. The scion stick is given a long slanting cut on one side and a small short cut on the other so as to match the cuts of the stock. The scion is inserted in the stock so that the cambium layers come on the longer side. The graft union is then tied with polythene strip as recommended for inarching. After the scion takes and remains green for more than 10 days, the rootstock should be clipped in stages. The scion wood to be used for veneer grafting requires similar preparation. The desired shoots should be defoliated at least one week prior to grafting so that the dormant buds in the leaf axils become swollen.
