Present research was carried out with the aim of identifying effect of salt stress (NaCl 0.0, 50, 100, 150 and 200 mM) on growth and physiological parameters of fenugreek (Trigonella foenum-graecum L.) variety RMt-1, a leafy vegetable. Various parameters such as germination percentage, shoot and root length, shoot-root ratio, number of leaves and branches, vigour index, fresh and dry weight, moisture content, relative water content and photosynthetic pigments were analyzed. All the parameters were recorded at 15, 30, 45 and 60 Days After Sowing (DAS). Analysis revealed a significant reduction in all parameters with increased salt concentration. Severity of salinity were also observed with increased age as increase in all growth parameter were non-significant in stressed plant as compared to non-stressed plant. A significant reduction from 100-30% was observed in germination percentage under salt stress. High salt concentration delayed the process of germination. Shoot length and root length was significantly reduced from 38.83 cm (control) to 9.44 cm (200 mM) and from 7.48 cm (control) to 2.44 cm (200 mM) respectively at 60 DAS. This analysis was further supported by fresh and dry weight of shoot and root, shoot/root ratio and moisture content. Present study concluded that the effect of salt toxicity was more prone in shoot as compared to root. The study also signified salt dependent behaviour of different photosynthetic pigments. A positive correlation was observed between stages of growth and reduction in parameters under salt stress. Overall study concluded that fenugreek variety RMt-1 is sensitive towards higher concentration of salts.

“…The decrease in the rate of coleoptile's emergence under high NaCl concentration was observed in other plants (Bounaqba, 1993) reflecting the slowdown in reserve mobilization to seedling (Prisco et al, 1981). Results indicated that salinity induced delay and decrease the germination percentage through lower water uptake and higher accumulation of Na + and Cl - (Begum et al, 2010). As salinity enhances osmotic pressure leading to a reduction in water absorbance, division and cell differentiation, which negatively affects metabolic and physiological processes.…”

The present work aims to study the germination behavior of seven Tunisian varieties of barley (Kounouz, Faiz, Roho, Manel, Lemsi, Rihane and Tej) during germination without or with NaCl. These varieties have been chosen in order to have the greatest possible diversity on the agro-physiologic level and to select tolerant plants to salinity. Barley grains are germinated (in Petri dishes lined with a double layer of filter paper soaked) in a solution of NaCl 0, 50, 100, 150, 200 mM for 7days. Two germination criteria were studied: the radicle breaching and the coleoptile's emergence. The measured parameters were the kinetics, the germination rate, the final germination and the GSI (Germination Stress Index). The results showed that, daily germination decreased significantly under NaCl. If we consider the two germination criteria, salt exerts a depressive effect on seed germination capacity of barley and slows germination speed. There is also an important intra-specific variability opposite of salinity. The studied barley varieties were classified in descending order of salt tolerance as following: Roho > Faiz > Kounouz > Manel > Rihane > Lemsi > Tej.

Salinity is one of the major environmental stress factors that cause many adverse effects on growth and productivity of plants. The objective of the present study was to investigate the effects of salinity levels on seed germination indices and protein patterns in Melissa officinalis seedlings. An experiment was carried out based on randomized complete block design with five concentrations of NaCl and four replicates with sand medium. The results indicated that salt stress had negative effects on the seed germination percentage (GP), mean germination time (MGT) and germination rate (GR), primary shoot and root length, as well as the protein content. After two days of salt exposure, the lowest (0%) GP was obtained for seeds treated with 12 dSm -1 salinity, as compared to the control (48.5%). Although, high salinity levels delayed seed germination, but during the experimental period GP increased and no significant differences were observed among the treatments in terms of GP after two weeks. The highest MGT (4.97 days) was obtained for plants stressed with 12 dSm -1 salinity level, as compared to the control (1.89 days). Analysis of the protein bands revealed that salinity suppressed the expression of two proteins with the size of 45 (Y1), and 40 kDa (Y2) and protein of 60 kDa (D1) was down-regulated. Also, the synthesis of four proteins of 70 (X1), 30 (X2), 25 (X3), and 20 kDa (X4) was induced in the seedlings under salinity stress. The changes in protein pattern under salinity stress indicated that the synthesis of new proteins may be associated to the stress specific proteins.
