Compatibility and verdure of seedling for autochtonous peer in the region of north Montenegro

Abstract

The study was conducted in three successive years to examine the compatibility and verdure in nursery trees of autochthonous peer cultivars grafted on Quince MA and wild peer seedlings (Pyrus communis L) during the first year after bud grafting. The aim of this paper is to determine compatibility and verdure of autochthonous peer seedling sorts (Pecanka, Jerebasma, Lubenicarka, Sinka, Tursijaca and Jarac) with the Quince MA and wild peer seedlings (Pyrus communis L). The severity of incompatibility varies between varieties but is always more severe with Quince MC than Quince MA. The incompatibility expresses itself in several ways. Firstly a poor ?bud? or ?graft? take in the nursery will be evident, secondly even if growing successfully in the nursery very often when ?lifted? breakages (brittle unions) occur between rootstock and scion and thirdly ?delayed? incompatibility where again the union between rootstock and scion breaks suddenly in later years, this is unpredictable and can often happen when there is a heavy crop load assisted by strong autumnal winds. The production of seedling material of autochthonous sorts with vegetative rootstocks Quince MA will be enormous contribution for even partially saving of fruit genofond that is the unity product of our ecological environment and autochthonous biocenosis.
