CALLUS INDUCTION OF LOCAL GARLIC CULTIVAR (ALLIUM SATIVUM L.)

ABSTRACT





An experiment was conducted during

the 2011/2011 cropping season at Plant Science and Biotechnology Laboratory,

Department of Biological Sciences, Nasarawa State University, Keffi, to study

the callus induction of garlic (Allium

sativum
L.) at various combinations and concentrations of growth regulators

and also to develop an efficient protocol for callus induction of garlic via

economically viable explants of indigenous garlic accessions. Garlic cloves used

as explants, were collected from bulb germinated in a Murashige and Skooge (MS)

basal medium. Different combinations and concentrations of growth regulators

like 2, 4-D and coconut water were used in MS medium to observe the
callus induction,

proliferation and organ formation. The highest callusing was recorded at the

best concentration of 2, 4-D (1.0 mg L-1) in MS medium (83.33%). The

implication of this result to further work on selection and improvement of this

crop is discussed.
