A slim veneer of wood some 40 to 50 mm long is cut on the stock to a thickness no more than 1/3rd the diameter of the stock. The scion is cut to a duration of 60 to 90 mm. Sections of non-terminal wood can be used if the scion branch has been cinctured. Scions must be mature terminals, preferably cinctured 30 days previously. Stocks should be 9 to 18 months old, 200 to 400 mm high & with at least 10 pairs of leaves. The grafts are maintained in the shade for some time before transferring them in the field. Vigorous sprouting of the scion specifies the successful union of the graft joint. The scion stick is then inserted in the cleft of the rootstock & tied with polythene strip. Similarly, 4 to 6cm long cut is made in the middle portion of the rootstock. In this grafting method, a wedge-shaped cut is made on the lower part of the scion stick. Defoliation prior to grafting method helps in swelling of a dormant bud of the scion resulting in greater success. The selected scion must be defoliated while on the mother plant at least 7 days before grafting, keeping a part of petiole intact on the selected shoot. The rootstock of ‘Ryan’ is generally used for soft-wood grafting. ![]() The scion should be a terminal non-flowering shoot of 3 to 4 months maturity with the same thickness as the rootstock. The method of soft-wood grafting is similar to that of cleft or wedge grafting. The success rate of the grafts is high as compared to those obtained in the rainy season.ĭifferent Grafting methods used in Sapota: Soft-Wood Grafting: However, grafting through February-March is more economical as the grafts will have to be maintained in the nursery for a shorter period of time. But in the monocots that have no vascular cambium, successful grafts are rare & difficult.Īpproach grafting must be preferably done at the beginning of the rainy season or during February-March. Grafting applies to the dicots and to the gymnosperms because of the presence of a continuous vascular cambium between the xylem & the phloem. A grafted Sapota plant, therefore, is a composite of parts derived from two or more plants. Plant grafting is a process in which parts of plants are joined together with the ultimate intention of making them unite and continue growing as one plant. The success of this joining requires that the vascular tissue grows together & such joining is called inosculation. The upper part of the combined plant is called the scion while the lower part is known as the rootstock. What is grafting?, grafting is a horticultural process whereby tissues of plants are joined so as to maintain their growth together. Percentage of success in air layers can be improved by applying 100 to 200ppm of Indole butyric acid solution on the ringed bark before wrapping with moss grass & plastic sheet. Air layering is done in monsoons (July-August). Sapodilla can be propagated through grafting and air layering. A mature Sapota fruit when scratched slightly with nail shows a yellow streak instead of the green streak. Fruits at full maturity grow a dull orange or potato color. Fruits normally mature in about 240 to 270 days after flowering.The optimum temperature ranges between 12 ☌ to 36☌. It prefers warm and humid weather and grows in both dry & humid areas. The Sapota is a tropical fruit crop & can be grown from Sea level up to 1200 m. ![]() The fruit may be seedless or may have 3 to 5 black shining seeds. Flowers have six sepals 6 stamens which are petaloid. Fruit bearing is on a new development in axils of leaves. It has a strong trunk on which scaffolds increase at regular intervals. ![]() The tree canopy has four kinds, viz, erect growing with drooping branches, spreading branches with sweet fruits & spreading branches with inferior fruits.
