Effects Of Cashew Leaves And Stem-Bark Extracts On The Germination Of Cowpea (Vigna Unguiculata L. Walp) And . - Pigeon Pea (Cajanus Cajan L. Millsp) Seeds:- Ukaegbu, florence. O
ABSTRACT
The experiment
was conducted to observe the inhibitory effects of the leaves and stem-bark
extract derived from Anacardium occidentale (Cashew) from the National Root
Crops Research Institute Umuahia, Umudike in Abia State on the germination of
Vigna unguiculata (Cowpea) and pigeon pea (Cajanus cajan). The experiments were
set on sterilized Petri dishes with a photoperiod of 24hours. Different
concentrations of the aqueous extracts (i.e.30%, 50% and 70%) were prepared and
administered to the seeds while distilled water was used as the control of the
experiment. The aqueous extracts of both the leaves and stem-bark caused
inhibitory effects on the germination percentages of cowpea and pigeon pea and
increased with the increase in the concentration of the extracts. The stem-bark
extracts of T, (70%) had the highest inhibition percentage value of (36.67%)
for cowpea and (86.66%) for pigeon pea and the lowest inhibition percentage value
was recorded in control and T, which had the inhibition of (60.00%) for control
and (53.33%) for T,, while in the leaf extract the highest inhibition
percentage was recorded in T, for both seeds which had (16.66%) for cowpea and
(80.00%) for pigeon pea, while the lowest inhibition was in control, followed
by TI in the leaf extract. These findings showed that certain phytochemicals in
the tissues of A. occideccntale caused significant phytotoxic effects on the
germination of cowpea and pigeon pea seeds. The study also revealed that
inhibition of the leaf aqueous extract effect was more pronounced on the
germination of both seeds (Cowpea and Pigeon pea) .
