Abstract
Obavljeno je kemijsko prorjeđivanje plodova jabuka (2000.) kod promjera 7,3 mm (sorta Gloster) i 9,3 mm (sorta Jonagold)Mesurolom® WP 50 u koncentraciji od 1800 ppm. U 2001. godini intenzitet diferencijacije na tretiranim stablima sorte Gloster bio je dobar kod štrljaka i stapki, a mali kod dugih šiba. Netretirana stabla sorte Gloster imala su nedovoljnu diferencijaciju. Na tretiranim stablima sorte Jonagold bila je dobra diferencijaciju kod štrljaka, a slaba kod stapki i dugih šiba. Kod netretiranih stabala sorte Jonagold, diferencijacija na štrljcima bila je umjerena, a na stapkama i dugim šibama nedovoljna.Chemical thinning of apple fruits 7.3 mm (cv. Gloster) and 9.3 mm (cv. Jonagold) in diameter was performed with Mesurol® WP 50 (concentration 1800 ppm). In 2001, intensity of differentiation on the treated Gloster cultivar trees was good in spurs and long bearing wood, and inadequate in one-year shots. Differentiation in untreated trees was inadequate. In Jonagold, differentiation was good in spurs, and poor in long bearing wood and one-year shots on the treated trees. In untreated trees, the differentiation in spurs was moderate
whereas in long bearing wood and one-year shots inadequate
