This experiment was carried out in three levels of water stress
(−0.4 and
−0.8 Mpa osmotic potentials and distilled water as a control)
under different temperature incubations (10, 15 and 25 ◦C). For
the germination tests, four replicates of 50 seeds of unprimed seeds
were surface sterilized and imbibed on two layers of blotter paper
in 9-cm-diameter Petri dishes at 10, 15 and 25 ◦C incubation under
different water stress. The germination performance was evaluated
as described above.
