Investigation of in vitro grafting successes between rootstock clonal genotypes and some prunus species

This study was carried out in Biotechnology Laboratory of C.U. Faculty of Agriculture, Department of Horticulture during 2004-2006. The shoot tips of AK-1 (Nonpareil x Peach), AK-2 (Nonpareil x Peach) and GF-677 almond x peach hybrid genotypes and Ferragnes, Francoise and Ninfa genotypes taken from the orchards of C.U. Faculty of Agriculture, Department of Horticulture were used. As the experimental material the viability, shoot elongation and micrografting of the shoot tips were investigated .In the experiment, MS macro and micro nutrients, vitamins and Fe-Na EDTA composition was used. During shoot elongation and multiplication stage 1 mg/l BAP and 0.1 mg/l GA3 plant growth regulator concentrations were used.In this work, viability rate was found to be 50 % in AK-1, 25 % in AK-2 and 37.5 % in GF-677, 85 % Ferragnes, 1 % Ninfa, 1 % Francoise; multiplication rate was 3 shoot/explant in AK-1 genotype, 2 shoot/explant in GF-677 and 8 shoot/explant in AK-2 genotype, 3 shoot/explant in Ferragnes genotype; micrografting rate was 25.1 % in AK-1 genotype, 25 % in GF-677 and 34.4 % in AK-2 genotype.
