Superior In Vitro Responses of a Native Rose Genotype to Driver Kuniyuki Walnut (DKW) Medium in a Comparative Study Using Natural and Synthetic Plant Growth Regulators.

is one of the precious native rose rootstocks with a high reputation among plant producers, which has potential horticultural and pharmacological properties related to the cosmetic values and the production of secondary metabolites. Due to high horticultural consumption, applying the plant tissue culture technique as a major tool for healthy and massive-scale production of plants is not unexpected. However, the response of in vitro plantlets to various plant tissue culture ingredients is not well understood to tender an efficient applied protocol for qualitative and quantitative in vitro propagation. In this regard, the main objective of this study is to investigate the influence of several abiotic in vitro variants including six plant tissue culture media formulations (McCown's Woody Plant Medium (WPM), Murashige and Skoog (MS), Van der Salm (VS), Schenk and Hildebrant (SH), Driver Kuniyuki Walnut (DKW), and Gamburg B5 (B5)) in combination with four concentrations (0, 1.5, 3, 4 mgL) of two types of cytokinins (6-Benzyaminopurine (BAP) and Kinetin (Kin)) simultaneously. Notably, it is perceived that DKW culture medium containing 1.5 mgL BAP and 0.1 mgL NAA is the best treatment for both in vitro morphological and flowering properties.
