Abstract
An in uitro seed culture system was estabIished to grow peanut
seed of different maturities viz. white, yellow, orange, brown and
black, using a modified Murashige and Skoog medium. Under this
system peanut seed of yellow, orange, brown and black maturity
categories grew to maturity as measured by increase in their size and
germinability. In oitro cultured seeds produced significant amounts
of phytoalexins and were contaminated with aflatoxins following
their inoculation with Aspergillus spp. while the noninoculated
sterile controls did not produce any phytoalexins. Exposure of seed
cultures to water stress using various concentrations of mannitol(0
to 1 M) and polyethylene glycol 8000 (0-30% w/v) caused asignificant
decrease in their phytoalexin producing ability, and enhanced
fungal growth compared to the nonstressed controls.
