Jack Fruit (Artocarpus heterophyllus Lam.) Propagation Testing Three Types of Bud Graft

The Jack fruit trees produced by seeds, are usually more precocious than the majority of other fruit-bearing species, nevertheless, this spread generates variability in size and forms of the trees. The grafted trees can begin to produce fruits in the third year. The spread by means of graft is very important, since the utilization of plants grafted on the establishment of new gardens, it allows homogeneous and to raise the yields of the plants; as well as the resistance to diseases, plagues and to the preservation of improved varieties or native types. The aim of this experiment was to evaluate the efficiency of three methods of bud graft  for the asexual spread of plants of jack fruit. Methods of bud graft: "T", patch and splinter were evaluated. The experiment was developed in Colima's University, campus Tecomán, with a tropical very hot climate, (BS1) and to 33 meters on the level of the sea. The rootstocks were 'Criollo', of seven months of age. The donating trees of vegetative material are located in the same zone, they were selected by your good fytosanitary condition, productivity and good size of fruit, in full production. Sub terminals scions were used, defoliated and disinfected with fungicide and were grafted the same day of your cut. The experimental design was completely at random The results indicate that the best type of graft after 60 days was that of patch with 35 % (seven plants) of grafts successfully. Other treatments answered with very much vigor, but after 26 days of remaining latent, the vascular bundles were not re-established and initiated to be dehydrating and later they dried off.
