Feathering ability of apple, pear and cherry nursery trees treated with different branch-inducing methods

Popis výsledku v původním jazyce

To provide fruit growers with planting material with good quality of lateral branches, it is usually necessary to use some branch-inducing method. In 2016, we tested chemical and mechanical methods of branch inducement as well as their combinations in three fruit species, each represented by two cultivars: apple (‘Galaval’, ‘Red Bohemia’), pear (‘Bohemica’, ‘Dicolor’), and sweet cherry (‘Kordia’, ‘Samba’). Among others, we tested feasibility of a modified notching technique, which was performed during the summer to induce sylleptic branching of sweet cherries. Length and number of the laterals classified in three categories (1-10, 10-30 and >30 cm) was the main indicator of quality. For hard to branch apple cultivar ‘Red Bohemia’, the best results were reached when the trees were treated with benzyladenine in combination with pinching of the terminal leaves. The best results for ‘Galaval’ were obtained when a mixture of benzyladenine and gibberellins was used alone or in combination with pinching. Hard to branch pear cultivar ‘Dicolor’ did not respond positively to any treatment. Well branching ‘Bohemica’ showed the best feathering when treated with the mixture of benzyladenine and gibberellins, nevertheless, differences among the treatments were small. No efficient treatment was found for branch inducement in a sweet cherry cultivar ‘Samba’. The best efficiency in ‘Kordia’ was reached by combination of benzyladenine and pinching of the leaves, however, the number of the induced branches was not sufficient. The modified notching method was not sufficiently efficient, moreover, it was accompanied by unacceptable wilting and necrosis of the growing tips. Nevertheless, further testing of this method will continue.
