Vegetative growth parameters of quince cultivars

Abstract

The vegetative growth parameters of eight quince cultivars were examined in the four-year period (2010-2013). Studied cultivars differed significantly based on all examined parameters. Trunk circumference, trunk cross-sectional area and tree height were the lowest in the ‘Leskovačka’ cultivar, and the highest in the ‘Portugal’ cultivar. In addition, the ‘Portugal’ cultivar had the largest dimensions of the crown. Based on the examined parameters quince cultivars were divided on dwarfing (‘Leskovacka’), medium-vigorous (‘Vranjska’, ‘Pazardžijska’, ‘Hemus’ and ‘Asenica’) and vigorous (‘Portugal’, ‘Morava’ and ‘Triumph’). This classification is very important to determine the optimal planting distance when establishing new quince orchards.

U četvorogodišnjem periodu (2010-2013) ispitivani su pokazatelji vegetativnog rasta osam sorti dunje. Proučavane sorte su se značajno razlikovale na osnovu svih ispitivanih parametara. Obim, površina poprečnog preseka debla i visina stabla su bili najmanji kod sorte Leskovačka, a najveći kod sorte Portugalska. Pored toga, sorta Portugalska imala je i najveće dimenzije krune. Na osnovu ispitivanih parametara izvršena je podela sorti na slabo bujne (Leskovačka), srednje bujne (Vranjska, Pazardžijska, Hemus i Asenica) i bujne (Portugal, Morava i Triumph). Ova podela je značajna za projektovanje optimalnog razmaka sadnje prilikom podizanja novih zasada dunje.
