Age of scion 3 to 4 months 8. In the case of grafting using rootstock, wedge grafting is done. Performances of the composite trees were evaluated one year following grafting. b- Biogeain (3 and 6 gm.pot-1). Critical factors appear to be the grafting environment, and the rootstock and graftwood condition. Wedge grafting is a method of vegetative propagation which is standardized in guava propagation gave maximum number of success than other standard methods of propagation in guava. The grafting operation Methods The guava plants were subjected different grafting methods under different season of grafting for mass multiplication. The upper joined portion of the graft is called scion. The favorable condition prevailing inside the structure stimulating rapid Allahabad Safeda, Lucknow 49 and Lalit under greenhouse callusing and early contact of cambial layers, which enables as well as in open field conditions. The experimental material consisted of scion cultivar Allahabad Safeda. rootstocks which came directly from micropropagation had many suckers and burrknots and usually had poorly developed scions. Veneer, also known as bark or inlay, grafting is similar to side grafting and makes use of scions--cuttings a bit thicker than a pencil and 3 to 6 inches tall that include a few buds. In case of grafting using root stock wedge grafting is done. Pusa Urvashi. The grafting operation performed in greenhouse with polycap gave significantly higher success of grafts compared with other conditions of wedge grafting in all taken cultivars. The most suitable period for wedge grafting obtained at Grafting in Guava. Fruit quality parameters were also improved with application of different treatments. Cut off the upper portion of the rootstock specimen after the grafted bud produces 3 to 4 inches of new growth. Size of polyethylene bag 18 x 20 cm 4. STANDARDIZATION OF WEDGE GRAFTING TECHNIQUE 6After selection of the scion, rootstock is headed back by retaining 15â18 cm long stem above the polyethene bag.

K., Joshi, G, Traditional fruit cultivars are ontogenically very old, and therefore difficult to root. And major diseases are wilt of guava, fruit canker, Anthracnose and Cercospora leaf … Effect of time of grafting and polycap on leaf area, chlorophyll content, fresh weight and dry weight of sprout in plants of guava cv. Till date, there are several rootstocks evolved of which some have become commercial in many advanced countries. Present study revealed that wedge method of grafting was tried in guava (Psidium guajava) cultivars Allahabad Safeda Lucknow 49 and Lalit under greenhouse (GH) as well as in open field conditions with and without polycap. Watch for new growth to appear in your grafted scion. These rootstocks were grown in the field for one year and then grafted with scions of ‘Cox’s Orange Pippin’. Also 2nd April budding date was effective significantly in vegetative growth characteristics (budding length, leaves number, leaves area, leaves wet weight, leaves chlorophyll content, leaves protein, carbohydrates and nitrogen percent. American Int. methods of propagation viz., shield budding, patch budding, veneer grafting, wedge grafting and wedge grafting with polycap were tried on two rootstocks namely L-49 and local guava in both open and polyhouse condition. Various horticultural practices were Wedge grafting: Percentage success of wedge grafting is higher than that of patch method of budding. It was concluded that patch budding in July-August and soft wood grafting in April-May may be adopted in the region for multiplication of elite tamarind genotypes. 1 0 obj evaluate the success of grafting guava as a scion on accessions of cattley guava as rootstocks resistant to .
