اﺛﺮ ﺗﻨﺶ ﺷﻮری ﺑﺮ ﺧﺼﻮﺻﻴﺎت ﺑﻴﻮﺷﻴﻤﻴﺎﻳﻲ ﮔﻴﺎه داروﻳﻲ ﺷﻨﺒﻠﻴﻠﻪ (Trigonella foenum – graecum L)

In order to investigate the effect of different salinity levels on biochemical characteristics of medical plant fenugreek (Trigonella foenum-graecum L.) a factorial experiment was conducted in a completely randomized design with three replicates in the outside of greenhouse in 2013. Experimental treatments were Combination of eight fenugreek landrace (Isfahan, Tabriz, Hamedan, Sari ,Challous, Amol ,Mashhad and Yasooj) and four levels of salinity stress (0, 60, 120 and 180 Mm NaCl). Effect of different salinity levels on relative humidity, membrane stability, chlorophyll a and prolline of leaf significant differences (P≤0/01). Different levels of salinity led to significant reductions in all of measured traits. Comparison of treatment means revealed that the maximum amount of measured characteristics belonged to control (0 Mm). The Isfahan, Mashhad and Challous landraces showed the highest amount in most of the characteristics in comparison with others. According to current results, three landraces can be considered as the landraces which contains genes of salt tolerance used to modify landraces with high potential yield.
