Attached groundnut gynophores of Virginia line Virginia
bunch strain 1 (VB-1), Spanish line TMV-3 and Valencia line
CBBR4 were cultured singly in aerated, simplified nutrient
solutions consisting of (2 μM iron (Fe) and 0.5 μM zinc (Zn)
with or without 100 μM calcium (Ca). In all lines, normal
and apparently healthy pods were produced in solutions
containing Ca, whereas, pod growth was severely restricted
in solutions without Ca. Three of CBRR4 gynophores cultured
in solution containing Ca formed healthy tap roots. It was
concluded that a simplified solution containing only Ca, Zn
and Fe could support healthy groundnut pod growth.
Key words:
Arachis hypogeae,
groundnut gynophore, pod development, root formation,
solution culture.
