Abstract

Background and purpose:

Salinity is an environmental factor that all stages of plant growth and seed germination to fruit production of more or less affected. Germination, plant growth under salinity stress is one of the most critical stages.Under these conditions, Pretreatment a method of improving the germination and growth in environmental stress conditions. Seed treatment is a method by which the seeds before putting on her bed and exposure to environmental conditions, ecological, physiological and biochemical preparations find for germination. This study was carried out to evaluate the effect of pretreatment four landraces of fenugreek with salicylic acid on some germination indices, Fenugreek and identify the most tolerant landrace to salinity.
Materials and Methods:
In this study was conducted in a factorial arrangement in Completely Randomized Design with three replications in laboratory of ‘Unique Plants’ in Ferdowsi University of Mashhad in 2013. The treatments includes four levels of salinity (in four levels of 0, 60, 120 and 180 mM) of sodium chloride and salicylic acid (at a concentration of 0 and 1 mM), respectively. In this experiment were studied the effect of salicylic acid on germination of seed pretreatment with fenugreek four landraces under salinity stress. Traits measured were germination percentage, germination rate, root length, shoot length, root dry weight, shoot dry weight, seedling dry weight and root dry weight ratio were to shoot.
Finding:
The results showed that effect of population, salicylic acid and salinity on measured traits were significant at 1% level (p Conclusion:
According to the results, all treatments was significant on the traits while the interaction between landrace and the salicylic acid on shoot length, landrace and interaction of salinity and salinity and salicylic acid on root to shoot ratio and triple interaction salicylic acid, salinity, and a landrace in the measured traits were not statistically significant. Landraces of Isfahan and Amol more tolerant growth stages of the landraces showed Hamadan and Yasooj. Based on the results of this study appear to landrace as the landraces of the two salt tolerance genes used to modify the landraces with high performance potential.
