- Abstract
- Four callus lines from immature embryos of a
self-crossed maize (Zea mays L.) hybrid cultivar were selected
for \"high\" (two lines) and \"low\" (two lines) polyamine
(PA) levels. Each selected line was exposed to culture
media containing no (control) or 1% (0.171 M) NaCl
and the relative growth rates were compared after subculture.
Low-PA lines appeared to be tolerant to salt stress,
while high-PA lines were sensitive. Analysis of PA at the
end of the subculture showed that treated calli of sensitive
lines had increased their putrescine content in comparison
with their control, while putrescine remained constant in
tolerant lines. Callus lines were analysed by RAPD (random
amplification of polymorphic DNA) markers. One
polymorphism (550-bp band) was found, demonstrating a
genetic difference between the lines. (literal)
