چکیده
|
Beta vulgaris belongs to the family amaranthaceae and was found to have halophytic ancestors. the objective of this study was to investigate the effect of sodium chloride on seed germination, therefore the early stages of seedling growth of beta vulgaris grown under different salinity levels (0, 100, 150 and 200 mm of nacl) were studied. the experiment was laid out in a completely randomized design (crd) with four replications. it was revealed that as concentration of nacl increases, the rate and percentage of germination, length and fresh weight of radicle plumule and seedling vigour index decrease. in conclusion, our results indicated that salt stress decreased beta vulgaris seed germination and early seedling growth while induced changes in the anatomical characteristics such as increased level of cutin synthesis on epidermal leaves cells and altered the thickness of vascular system, epidermis and parenchyma in leaves, roots and petioles.

Abstract
|
Beta vulgaris belongs to the family Amaranthaceae and was found to have halophytic ancestors. The objective of this study was to investigate the effect of sodium chloride on seed germination, therefore the early stages of seedling growth of Beta vulgaris grown under different salinity levels (0, 100, 150 and 200 mM of NaCl) were studied. The experiment was laid out in a completely randomized design (CRD) with four replications. It was revealed that as concentration of NaCl increases, the rate and percentage of germination, length and fresh weight of radicle plumule and seedling vigour index decrease. In conclusion, our results indicated that salt stress decreased Beta vulgaris seed germination and early seedling growth while induced changes in the anatomical characteristics such as increased level of cutin synthesis on epidermal leaves cells and altered the thickness of vascular system, epidermis and parenchyma in leaves, roots and petioles.
