Abstract

Leaf explants of the cucumber (Cucumis sativus L.) were cultured on Murashige and Skoog's (MS) medium supplemented with various concentrations of $\alpha$-naphthalene acetic acid (NAA) and 6-benzylaminopurine (BAP). Direct shoot orgnogenesis as well as callus formation with somatic embryos and multiple shoots was observed from leaf explants of cvs. Shinhukjinju and Chungjang. The highest frequency of shoot formation 80% was observed on MS medium supplemented with NAA/BAP (5.0 ${\mu}{\textrm}{m}$/2.5 ${\mu}{\textrm}{m}$), with explants forming 3-7 shoots. Shoots formation occured within 3 to 4 weeks. Only one subculture of calli was required for plant regeneration on normal growth regulator-free medium. Plantlets transferred to soil developed into plants of normal appearance, which flowered and set fruits.
