%X the cocuy, agave cocui trelease is an important crop for the semiarid zones of the central-west part of venezuela. it is involved in a traditional production systems for liquor, soap, preserves, among others. it is the economical support of many families in lara state, venezuela. normally, the production was based in naturally occurring plants, so supply of plants is limited. in order to increase plant supply and improve the economical activity of these rural communities, asexual propagation systems have been implemented with slow growth rate and plant production not enough to satisfy the demand. a mass propagation system using axillary buds have been established. buds were placed on murashige and skoog (ms) medium supplemented with thyamine (1mg l-1), nicotinic acid (1mg l-1), pyridoxine hcl (1mg l-1), inositol (100mg l-1), ba (1mg l-1), ana (1mg l-1) sucrose (30 g l-1) and agar (5g l-1). forty explants were cultured in 10ml of culture medium, and were placed in the dark for 7 days. buds were placed under fluorescent light (16.95 w.m-2), at 28 ¡À 2 oc and a 16 hr photoperiod. shoots were observed 1 months after culture, an average of 6 shoots were observed for each cultured axillary bud. sprouting ratio was increased when temperatures was increased to 40 oc. complete plants were obtained by transferring shoots to medium with no hormones. transplant to soil (1:1:1 soil:sand:coconut sawdust) allowed plants to be acclimatized in 1 week. all plants have normal morphology. as a conclusion axillary bud in vitro culture can be referred as an efficient method to propagate a. cocui trelease
