Improving the Quality of Nursery Apple and Pear Trees with the Use of Different Plant Growth Regulators

Original language description

Modern fruit tree nurseries emphasize high productivity, production intensification, economic justification, and high final quality of the produced trees. The present study is focused on the effect of selected plant growth regulators (PGRs) on knip-boom apple and pear nursery trees with the aim of increasing quality and intensification and at the same time reducing the costs of production borne by wholesale customers. The experiment was performed over a period of three years to verify the effects of commercial products, such as Gibb plus, Globaryll 100 and Progerbalin LG, and of newly developed mixtures of various PGRs in various concentrations. Among the PGRs, BA, GA4+7, 24-epibrassinolide, 4-CPPU, Naptalam, TIBA, Paclobutrazol, Putrescine and Ethephon were used. The experimental verification was performed on ʻAdmiralʼ, ʻGalavalʼ, and ʻRubinolaʼ apple varieties and on ʻBohemicaʼ, ʻConferenceʼ, and ʻDecoraʼ pear varieties. The results showed that among the commercial products, the most effective for feather formation were Globaryll for apple trees and Progerbalin for pear trees at concentrations of 1.0% and 1.5%, respectively. Among the newly developed mixtures, the most effective for feather formation were Progerbalin+4-CPPU+Putrescine (1.5% + 0.01% + 0.15%) for apple trees and Ethephon+GA4-7+Putrescine (0.125% + 0.2% + 0.15%) for pear trees. The other measured parameters, such as tree height, feather length and trunk thickness were significantly affected by different PGRs. Furthermore, the application of Paclobutrazol in a mixture with TIBA or with Naptalam inhibited tree branching. The effect of the PGRs applications depended significantly on the fruit tree variety.
