“…The releases of this compound occurred under salt and water stresses and proline has a prominent role to trigger defense mechanism of the plants against the stress. Many plants accumulate non-harmful proline as an osmolyte under stress condition (Singh et al, 2000). Our results further indicated that MDA, proline and H 2 O 2 contents were increased in both tissues of lentil and barley plants exposed to 5 and 10 mM B ( Table 2).…”

In this study, the effects of different nitrogen sources on lentil (Lens clunaris) and barley (Hordeum vulgare) plants, exposed to 5 and 10 mM boron stress previously, were studied. After ten-day germination, the lentil (native) and barley (Tokak157/37) were incubated 16 h light and 8 h dark per day for 7-day growth cycle under the conditions of boron stress via different nitrogen sources (10 mM nitrogen in NH 4 Cl, KNO 3 and urea). As a result of the changes in the nitrogen sources of the plants, there were determined decreases in the relative growth rate (%) and total chlorophyll content related to boron stress, (p < 0.05) and (p < 0.01), respectively. The changes in the lentil were obtained much more than those in the barley. In addition, the changes in the groups in which NH 4 + was used as nitrogen source were obtained at lowest levels. The concentrations of MDA, H 2 O 2 and proline showed increases under boron stress (p < 0.05). The effect of boron toxicity on the activities of SOD, GPX and LOX was similar in the two species but the levels of CAT and APX activities were different in both species under 5 and 10 mM boron stress (p < 0.01). SOD, GPX and LOX activities increased in the roots and shoots of boron treated plants as compared with the controls (p < 0.01). Although, lentil CAT and APX, activities decreased; in barley, CAT and APX, activities increased under boron toxicity. In conclusion, the fertilizers which contain NH 4 + should be used in the boron stressed farmlands.

“…Ionic balance in the plant vacuoles can be maintained by the accumulation of various compatible organic osmolytes in the cytoplasm 46, 47. Of various compatible solutes, proline is the important one which accumulates to a great extent in salt‐stressed plants 45, 48–52. In the present study, salt stress significantly increased leaf proline concentration in both safflower lines; however, salt‐tolerant Safflower‐39 was lower in proline content than that in salt‐sensitive Safflower‐33.…”

“…For maintaining ionic balance in the vacuole, cytoplasm accumulates low molecular weight compound which are termed as compatible solutes. These compatible solutes included mainly proline (Singh et al, 2000) and glycinebetain (Khan et al, 1998). They do not interfere with normal biochemical function of plants.…”

Salinity is an agro-environmental problem limiting plant growth and development in the arid to semi-arid regions of the world and becomes the predicament of serious concern. Plants exposed to salt stress may undergo osmotic stress, ion toxicity and nutritional imbalance which results in production of reactive oxygen species (ROS). The ability of plants to detoxify radicals under conditions of salt stress is probably the most critical requirement and is determined by multifarious morpho-physiological and biochemical pathways like initial entry of salt to roots, intercellular compartmentation, synthesis of osmoprotectants (sugars, amino acids, proline and upgradation of antioxidant system) that results in maintaining ion homeostasis. This paper also revealed the plant responses to salinity stress with emphasis on physiological and biochemical mechanisms of salt tolerance which may help in interdisciplinary studies to assess the ecological consequence of salt stress. Moreover, the application of potassium helps the plants to cope with the hazardous effects of salinity by improving the morphological, physiological and biochemical attributes.
