Shield budding

Abstract: SummaryThe use of chip budding to graft four apple cultivars onto a range of commercially important rootstocks in various combinations, produced larger and more uniform one-year-old trees, with more and longer lateral branches, compared with those raised by traditional shield budding using an upright ल incision in the rootstock, at both East Mailing and Long Ashton Research Stations. At Long Ashton, with Golden Delicious and Worcester Pearmain on MM. 106, but not at East Mailing with Cox on M.26, shield budding with an inverted ल incision was also superior to traditional shield budding, but it did not achieve as much improvement as did chip budding over the traditional method.Frost damage, causing bud death and the production of trees with weak unions, was much less severe on chip-budded trees than on those budded by the traditional shield method.The superior growth of trees raised from chip buds was associated with the formation of a complete union between scion and stock during the autumn after budding ...

Abstract: The ber (Zizyphus mauritiana) is an important fruit crop for arid and semi arid regions in tropical and sub tropical regions. Its origin is India. It is known for its ability to withstand adverse conditions. It is truly a desert apple of Thar Desert. It can be processed to prepare murabba, pulps, jam and beverage.Z. mauritiana cultivated in the tropical and subtropical regions of Indian regions. The commercial method of vegetative propagation is by budding. The best method widely adopted is shield budding (T or I budding). Success in micro propagation of ber in vitro from stem explants of mature tree was reported. Leguminous crops are preferred as intercrop. Ber fruits followed a double sigmoid growth curve. Fruits having a specific gravity of < 1 were considered to be ready to harvest. Powdery mildew is the most serious disease of ber and causes heavy losses.

Abstract: Seedling quality is essential for producing quality fruits and keeping the producer revenue. The main goal of this research was to investigate the effect of different environmental conditions and three grafting methods in the production of peach-tree seedlings ( Prunus persica (L.) Batsch). The experiment took place at the Universidade Federal de Lavras, Minas Gerais State, Brazil. The experimental design was completely randomized, in a 3x3 factorial scheme (three environments: plastic greenhouse, mesh of 50% of shading, and open field; and three grafting methods: shield budding, patch budding, and cleft grafting), with four replications and 12 plants per plot. ‘Okinawa’ was the rootstocks used, and buddings and grafts originated from the ‘Diamante’ peach-tree cultivar. The features evaluated were graft-take (%) and time to reach the first formation pruning (days). I t was concluded that the mean average graft-take percentage for all three grafting methods was 91.94%, independently of the environment. For all three environmental conditions studied, seedlings grafted according to the cleft grafting method were the fastest ones to reach the first formation pruning, while the patch budding method allowed less time for the first formation pruning, for the open field and mesh environments, when compared with the shield budding method. KEY-WORDS: Prunus persica (L.); environmental conditions; propagation.

Abstract: An experiment was conducted on bael to find out the effect of methods and time of budding under different growing conditions. Patch budding (P1) and shield budding (P2) were tried in four months, viz., June (M1), July (M2), August (M3) and September (M4) under two different conditions namely polyhouse and open field conditions. Patch budding with 84.20 per cent bud sprouting and 80.25 per cent bud survival proved superior to shield budding in polyhouse, however 72.50 per cent of bud sprouting and 69.20 per cent of bud survival recorded in open field conditions. Propagation methods gave better results during June. Polyhouse gave better response than open field conditions with respect to number of days taken to bud sprout (6.66 in July), per cent bud sprouting (85.50 in June), bud survival (91.25% in June) and sprouted shoot length (8.86 cm in July).
