Abstract

To evaluate the effect of salinity of Urmia Lake water on Lathyrus sp, as an adaptive crop to undesirable environment factors, a factorial experiment was carried out based on randomized complete block design with four replications. Treatments included application time of salinity (pre- and post germination) and salinity (0, 2, 4, 6 & 8 ds/m) of no magnetic and magnetic Urmia Lake water. Means comparison indicated that the longest root (1.75 cm), longest shoot (2.2 cm), greatest root dry weight (0.19 g) belonged to seedlings that treated with no magnetic Urmia Lake water before germination stage. The greatest shoot dry weight (0.15 g) belonged to seedlings that treated with 4 ds/m of no magnetic Urmia Lake water added after germination to Petri dishes. The highest shoot/root dry weight ratio (1.91) belonged to seedlings that treated with 4 ds/m of Urmia Lake water (no magnetic) added before germination to Petri dishes. However, the longest root (2.29 cm) and longest shoot (2.37 cm) belonged to seedlings that treated with Urmia Lake water before germination stage. The greatest shoot dry weight (0.079 g) belonged to seedlings that treated with 6 ds/m of magnetic Urmia Lake water added before germination to Petri dishes. The maximum shoot/root dry weight ratio (2.27) was occurred at 8 ds/m of Urmia Lake water (magnetic) added after germination to Petri dishes
