Crop load influence on apple

Cilj ovog diplomskog rada je prikazati utjecaj opterećenja rodom kod jabuke na diferencijaciju generativnih pupova kao i na morfološke parametre plodova. U intenzivnim nasadima jabuke važno je postići ravnotežu rasta i rodnosti te omogućiti što raniju punu rodnost. Primjenom različitih agrotehničkih i pomotehničkih zahvata od kojih su najznačajniji rezidba i prorjeđivanje plodova, postiže se ravnoteža između vegetativnog i generativnog rasta. Premalo ili preveliko opterećenje dovodi do razvijanja plodova nezadovoljavajućih standarda za tržište. Prva opterećenja na mladim stablima moraju biti određena na temelju karakteristika uzgajane sorte, sortnoj sklonosti alternaciji kao i na temelju poprečne površine presjeka debla (TCSA). Regulacija opterećenja rodom je neizostavan dio uzgoja jabuke, jer se na taj način osigurava redovita rodnost i proizvodnja plodova koji zadovoljavaju potrebe tržišta.The aim of this thesisis to present the influence of crop load on differentiation of generative buds and morphological parameters of fruit. In intensive apple orchards it is important to accomplish balance between vegetative and generative growth and to get into fruit bearing as early as possible. This balance is accomplished with various agrotechnical and pomotechnical operations. The most important are pruning and thinning. Wrong intensity of crop load can lead to having fruit which does not have satisfying parameters for the market. First crop loads on young trees must be determined by sort characteristics, biennial bearing tendency and trunk cross section area. Cropload regulation is indispensable part of apple production because it ensures regular fruit bearing and production of fruit that is satisfying for the market
