摘要：

Indirect organogenesis was developed in Agave tequilana. Leaf segments and meristematic tissue from the central head ('pina') were evaluated as explant sources. A minimal-sized explant with high bud-forming capacity (19.5 BFC) was obtained through a cross section of meristematic tissue from in vitro plantlets. In callus culture, the best growth response was due to naphthalene acetic-acid (NAA) presenting a contrasting response compared to 2,4-dichlorophenoxyacetic acid (2,4-D). Regeneration from meristem segments and callus was obtained using 1.1 mu M 2,4-D and 44 mu M 6-benzylaminopurine (BA). The regeneration capacity of callus was maintained for 3 mo. Shoots regenerated were rooted in a hormone-free MS1 medium and acclimatized in a greenhouse with a 100% survival.
