ﺑﺮرﺳﻲ اﺛﺮ ﺗﻨﺶ ﺷﻮری ﺑﺮ ﺻﻔﺎت ﻣﺮﺗﺒﻂ ﺑﺎ ﻋﻤﻠﻜﺮد در ﮔﻴﺎه داروﻳﻲ ﺷﻨﺒﻠﻴﻠﻪ(.Trigonella foenom-graecum L)

Salinity is considered as an important environmental stress and major problem in agriculture for arid and semi arid regions. Fenugreek (Trigonellafoenum-graecum L.) is one of the important medicinal plant that uses in the pharmaceutical industry. In order to investigate the effect of salinity stress on yield and yield components of eight landraces of fenugreek and identify the best landraces 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 ,Challus, Amol ,Mashhad and Yasooj) and four levels of salinity stress (0, 60, 120 and 180 Mm NaCl). The results of the analysis of variance revealed that in terms of plant height, 1000-seedweight, pod length and pod width between all levels of salinity there were a significant differences and the characteristics in the last level of salinity were decreased by 58.39 %, %33.46, %30.41, %16.72compared to control, respectively. There was significant differences (P≤0/01) between landraces based on all the studied traits. The mean comparison of yield showed that the Mashhad and challus landraces were the most resistant and Tabriz, Hamedan and Yasooj were most sensitive landraces to salinity.
