Effect Of Salt Stress On The Growth And Nitrogen Assimilation Of African Yam Bean (Sphenostylis Stenocarpa) (L.):- Kalu, Patience E.
ABSTRACT
The
effect of salt stress on the growth and nitrogen assimilation of Sphenostylis
stenocarpa (African yam bean) was investigated. There were five treatments (0.0
l mOl/1, 0.03mol/l, 0.07mol/l, 0. 1 0mol/l) and the distilled water without
salt served as control. Treatment started three (3) weeks after germination and
was carried out once. The measurement of the plant started immediately after
treatment was done for one month. The research lasted for three months. Four
seeds were planted per plastic bucket and were thinned down to two. Salt stress
significantly (P <0.05) affected the growth and-nitrogen assimilation of
Sphenostylis stenocarpa (African yam bean),at higher salt (Nacl) concentration
(0.07mol/l and 0.10mol/l), the length of shoot, number of branches number of
leaves, root biomass, shoot biomass, germination and the nitrogen content of
the plant's leaf and soil were significantly (P<0.05) reduced. However, at
lower concentration (0.01 mol/1 to 0.03mol.l) the effect of salt stress on
these parameters was not significant. The reduction in growth and nitrogen
assimilation of Sphenostylis stenocarpa as a result of salt stress might be due
to the deleterious effect of salt stress on the cellular as well as all other
aspects of plant metabolism. Germination test was also carried out and lasted
for only four days. At 0.07mol/l it tends to be retarded compared to the other
treatment. The results obtained were discussed in the light of current
literatures.
