Morphological properties of apricot cultivars tree

Abstract

Morphological properties of 35 apricot cultivars in the period of initial cropping (four-year old trees) and also in the full cropping (seven-year old trees) were studied. Trunk girth and crown shape index had considerably less coefficients of variation than dimensions of the crown. Tree properties showed less variability in older than in younger trees. Among investigated cultivars, dominate those with strong (16 cvs) and intermediate vigour (14 cvs), whereas only five cultivars were classified in the week vigorous group.

Morfološke osobine stabla proučavane su kod 35 sorti kajsije u periodu početne rodnosti (starost stabala četiri godine), kao i pune rodnosti (starost sedam godina). Obim debla i indeks oblika krune su imali znatno manje koeficijente varijacije u odnosu na dimenzije krune. Osobine stabla su ispoljile manju varijabilnost kod starijih nego kod mlađih stabala. Među proučavanim sortama dominiraju bujne (16) i srednje bujne (14), dok je samo pet sorti svrstano u grupu slabo bujnih.
