Phenological Study on Peach Varieties in the Area of Dubrave Plateau in Herzegovina

Abstract

The aim of this study is to examine dynamic and energy of flowering, as well as phenophase of ripening for peach varieties Maycrest, Springcrest, Spring Lady, Rich Lady and Elegant Lady in the area of Dubrave plateau in Herzegovina in 2009-2011 period. The results of research show that statistical differences does not exist in the beginning of flowering between varieties (1-3 days), there is correlation between the beginning of flowering and ripening. Climatic factors had significantly great influence on the the beginning and the duration of the flowering of peaches, and therefore in the areas with increased risk of spring frosts it is recommended to cultivate varieties with later flowering period.

Cilj rada je ispitivanje dinamike i energije cvjetanja, te fenofaze zrenja sorti breskve Maycrest, Springcrest, Spring Lady, Rich Lady i Elegant Lady na području Dubravske visoravni u Hercegovini u periodu od 2009-2011. godine. Rezultati istraživanja pokazuju da nisu ispoljene značajne razlike u vremenu početka cvjetanja između sorti (svega 1-3 dana), niti postoji korelacija između vremena cvjetanja i zrenja. Na početak i trajanje cvjetanja breskve znatno veći utjecaj imali su klimatski faktori, te se u područjima povećane opasnosti od proljetnih mrazeva preporučuje gajenje sorti kasnijeg vremena cvjetanja.
