Aim: Effect of nine
seed pretreatments and seven soil types was studied on seed germination and
seedling growth of Balanites aegyptiaca (L.) Del., an endangered
medicinal plant, under growth chamber and greenhouse conditions, with a view
to enhance its propagation and growth.
of 10 lots of 100 seeds each, nine were soaked separately (1) in concentrated
H2SO4 for 5 min, 10 min and 15 min, (2) in water for 24
hr, 48 hr, and 72 hr, and (3) in boiling distilled water for 5 min, 10 min
and 15 min. One (untreated) lot was used as the control. Pre-treated seeds
with the best % germination were sown in 7 types of soil, viz. Sand, Clay,
Sand + Clay (1:1), Sand + Clay (2:1), Sand + Clay (1:2), Sand + Clay + Peat
moss (1:1:1) and Sand + Clay + Peat moss + Perlite (2:2:2:1).
pretreatments had a significant effect on seed germination, the highest
germination percentage (82.5%) coming from soaking in water for 24 h. The
least mean germination time (14.5 days) was obtained with seeds soaked in
water for 15 min, although they showed a low (25%) germination percentage.
Among the soil types, pure sand was the best, giving the highest (82%)
germination percentage and the least (18 days) mean germination time. With
reference to parameters related to seedling growth, combination of sand, clay
and peat moss (1:1:1) was the best media for cultivation of this species,
resulting in the maximum height (64.1cm), girth (3.6mm) and vigor index (50)
of the seedling after a six month growth. ??
seeds in water for 24 hr was the best pretreatment for optimal germination
performance. Sand was the best germination media, which became highly
favourable for seedling growth on being supplemented with clay and peat moss.
