Turnayemişi (Vaccinium macrocarpon Ait.) odun çeliklerinde köklenme ve kök gelişimi üzerine dışsal IBA uygulaması ile çelikteki yaprakların etkisi

Abstract

Cranberry is an important small fruit used as functional food. In this study, hardwood cuttings collected from 'Pilgrim' cv. in March from one-year-old uprights on the runners, also called stolon, belonging to four-year-old cranberry plants. Three Indole-3-butric acid (IBA) concentrations (0, 1000 and 2000 ppm) were applied to the cuttings prepared with or without leaves. Cuttings planted in peat medium in trays and trays placed in benches with 24°C bottom heating and cuttings leave to rooting under 30% shading with over misting system as needed. The rooting and rooting rate (%), rooting degree (1-9), shoot length (cm), root fresh weight (g), total root length (cm) and root diameter (mm) were determined. In leafy cuttings with 2000 ppm IBA applied, shooting (100%) and rooting (99.00%) were the highest. Leafy cuttings give the highest results in terms of all properties, while the highest rooting rate was obtained from 1000 and 2000 ppm IBA application (85.00%). The degree of rooting was the highest at the control IBA dose (6.53) and the root fresh weight at the 2000 ppm IBA dose (6.20 g). As the dose of IBA increases, the rate of shooting and rooting and the diameter of the root increase, total root length decreased and rooting degree, shoot length and fresh root weight are not affected much. On the other hand, leafy cuttings gave higher results in terms of all the properties examined.
