Title

Study of some Morphological Responses of Stevia (Stevia rebaudiana Bertoni) to Chitosan Elicitor under Salt Stress

Pages

  150-161

Abstract

 Salt stress is one of significant Abiotic stresses which has negative effects on growth and production of important Medicinal plants such as stevia. Thus, the aim of this study was to evaluate the interaction of chitosan in four levels (, , and g/L) and salt in four levels (, , and mM NaCl) on some of morphological properties of stevia based on factorial completely randomized design with three replication at Sana Institute of Higher Education in-. The traits studied were plant height, fresh and dry weight of root and shoot, number of leaf, internode number, root height, leaf area index (LAI), relative leaf growth rate (RLGR) and leaf area rate (LAR). The results of analysis of variance showed that salt stress resulted in significant change of plant height, leaf number, internode number, fresh and dry weight of root and shoot, RLGR, LAR. However, the interaction of chitosan and salt stress caused improvement in the each trait above mentioned. For instance, the increase of internode number in Ch S ( g/L chitosan-mM NaCl), leaf number, fresh and dry weight of root and shoot and root height in Ch S ( g/L chitosan-mM NaCl), plant height in Ch S ( g/L chitosan-mM NaCl) and Ch S ( g/L chitosan-mM NaCl) was indicated. In addition, the treatments of Ch S ( g/L chitosan-mM NaCl), Ch S ( g/L chitosanmM NaCl) and Ch S ( g/Lchitosan-mM NaCl) on LAR, Ch S ( g/L chitosanmM NaCl) on RLGR showed significant increase. Therefore, the achievement of this study could present profitable data with respect to morphological traits variation in stevia under salt stress condition and chitosan Elicitor in order to conserve these plants by improvement of these traits under stress.
