a variety of responses to salt stress that enable them to tolerate and survive
in such conditions. Salinity affects physiological and biochemical processes
in plants. A short term salt stress induced physiological and biochemical response
were observed in P. glaucum. The experiment was conducted to understand
the influence of salinity on seed germination, proline and free amino acid accumulation
in P. glaucum. It was observed that as the salt concentration increased
the germination percentage decreased as compared to control as well as the root/shoot
length also decreased. This suggests that salinity greatly influences the germination
as well as the plant growth. The levels of biochemical components proline and
free amino acid were measured during the salt stressed condition. The 14 days
old seedlings were subjected to 4 salt treatments (50, 100, 150 and 200 mM NaCl),
free proline and free amino acids was calculated at 0, 12, 24, 48, 72 and 96th
hour. Proline and free amino acid content in the salt stressed tissues increased
with increase in salt concentration as well as with duration of salt stress.
This result suggests that proline and free amino acid acids acts as compatible
solutes in P. glaucum to protect the cellular macromolecules, maintain
the osmotic balance and also scavenge the free radicals under salt stressed
condition.]]>Abbaspour, H.,20126526529Al-Saady, N.A., A.J. Khan, L. Rajesh and H.A. Esechie,2012Trigonella foenum gracium L.).]]>7176185Bates, L.S., R.P. Waldren and I.D.
