The effects of salinity on some physiological,Anatomical and biochemical aspects of cowpea (vigna unguiculata (l) walp (legurninosae)
Abstract
Very little work has been done on the physiology
cowpea (Vigna unguiculata) and almost nothing so far, on its response
to salinity effects. Cowpea being a drought
resistant crop is suspected it might also to some
extent tolerate salinity.
The study was carried out in a transparent
polythene covered shade house, using salinized SOlj
cultures at, H20, 2.5, 5.0 and 10.0 mmhos em-1
salinity levels. Two varieties, Katumani-80 and V ita-l
were used for the investigations.
Germination experiments showed that Vi ta-l
r was poorer in germination in all salt treatments
than Katumani-86. growth was also significantly -~~ (P=O.OOl) reduced by increase in salinity. In VitaI,
growth was not significantly (P=0.05) affected by 5.0
and 10.0 mmhos em-.}. salinity IeveIs.
