Optimization of Conditions for In Vitro Culture of Selected Arbutus unedo L. Genotypes

The strawberry tree is an evergreen shrub that grows on sea-facing slopes under a Mediterranean climate. It has key role in the lives of rural inhabitants forested areas and one most promising species for developing new approaches cultivation improved fruit. As result growing interest farmers, selection studies have focused highly productive varieties Arbutus unedo, whereby there requirement selected to be propagated at large scale. In this study, vitro propagation potential A. unedo genotypes, YV2 YV4, was investigated. best results terms decreasing browning with high level sterilization were achieved 50% ethanol (1 min) 20% NaCIO (12 both shoot tip nodium explants. growth performance, genotypes displayed highest proliferation rate WPM medium-supplemented BAP (2.0 mg/L) added IBA GA3 (0.1 mg/L each), which number elongation also highest. microcuttings showed higher rooting rates when cultured medium, 2.0 IBA, whereas addition 4.0 NAA optimal YV4. resulting root quality sufficient surviving acclimatization stage. genotype effect clear all stages during parameters.
