TI  - Effects of Exegenous Glycine Betaine Treatments on Growth and Some Physiological Characteristics of Tomato under Salt Stress Condition
AB  - The effects of the exogenous foliar application of glycine betaine (GB) with different doses (0, 5, 10 and 20 mM)on plant growth, chlorophyll content, stomatal conductance, phenolic and proline contents in tomato grown under salt stress wereevaluated. Tomato plants (Lycopersicon esculentum Mill.) were imposed to salinity stress for 2 months with 75 mM NaCl. Saltstress reduced the growth, chlorophyll reading values and stomatal conductance in tomato. GB application decreased theinhibation of salt stress on tomato plant growth, and increased stomatal conductivity and chlorophyll content. The effective doseof GB was 10 mM to increase tolerance against salt stress. Plant height significantly increased in 5, 10 and 20 mM GB treatmentsby 2.2, 13.1 and 18.9%, respectively compared to the control. 5 and 10 mM GB treatments significantly increased chlorophyllreading values (51.18 and 53.44, respectively) compared with control (48.92). 10 mM GB exhibited a rapid increase in stomatalconductivity by 11.3% compared with control. Moreover, 10 mM GB showed an increase in proline content by 53.4% comparedwith control. According to results of our study, it can be suggested that exogenous GB treatments could mitigate the deleteriouseffects of salt stress in tomato.
