Seedling establishment is a critical stage that determines
production of crop at later stages, thus it necessitates studying the impact of
salt stress at primary level. Present study is aimed to evaluate the effect of
salinity stress on germination as well as growth of seedlings of T.
foenumgraecum. Seedling germination showed 100% germination of seeds upto 100mM
NaCl treatment but beyond it there is a sharp decline in germination percentage
as it showed 60% decline in 200mM NaCl added set. Salt stress at higher
salinity levels (beyond 100mM NaCl) also resulted in delayed seedling
germination. Results showed there is not much variation in 50 and 100mM NaCl
treatments in comparison to control. But it shows strong inhibition in terms of
length as well as fresh weight of different plant parts as cotyledon,
hypocotyls as well as roots of seedlings with increasing level of salt solution
particularly at higher salt treatments as 150 and 200mM NaCl treatments. This
decline was more prominent in roots (71.43% and 73.47%) then in shoots (54.8%
and 55.06%) and least in cotyledons (21.87% and 19.51%) in comparison to
control in 7 and 15 days old fenugreek seedlings. The increasing salt concentrations
increase the phytotoxicity of shoot and root and decrease the tolerance indices
and the seedling vigor indices - See more at:
