STUDIES REGARDING MICROPROPAGATION OF HYBRID BERRY CULTIVARS RUBUS LOGANOBACCUS L.H. BAILEY HYBRIDBERRY
Here, we established the protocol for plant regeneration of Rubus loganobaccus L.H. Bailey via in vitro micro pro-pagation. Apical meristem was used as the explants cultured on Murashige and Skoog (1962) medium (MS) supplemented with different concentrations of plant growth regulators, 6-Benzylaminopurine (BAP). For the cultivars Logan, Chehalem, Olalie and Kotata good results were obtained for 0.5 mg/l BAP concentration, whereas for the cultivars Santiam and Lincoln Logan results were obtained for 0.4 mg/l BAP concentration. The micro-shoots produced normal roots within two weeks of culture on the 50% MS medium with no supplement of plant growth regulators. Plantlets were transferred to celled trays where they grew well.
