Abstract: (120 Views)
Research into increasing plant tolerance for environmental stress can be an effective step to carry out sustainable production in agricultural systems. This study was performed to evaluate the application effect of chitosan on the morphological and physiological traits of the hyssop under salinity stress conditions. The experiment was conducted based on a randomized complete design with factorial arrangement of treatment and three replications at Gonbad Kavous University. The salinity factor included four levels (0, 50, 100, and 150 mM) of sodium chloride. The second factor was studied at four levels by non-application of chitosan and without priming (control), seed priming with distilled water, seed priming with chitosan, and chitosan foliar application. The salinity stress effect had a significant effect on all traits. The chitosan elicitor also had a significant effect on plant height, content of proline, and catalase enzyme. The effect of the interaction between salinity and chitosan was significant in all traits except the stem dry weight. The highest content of proline (19.21 μmol/g) belonged to chitosan foliar application under salinity stress of 150 mM treatment that increased. In the 50 mM salinity stress condition, seed priming with chitosan caused a 50% increase in proline content and soluble sugars compared to the control. Based on the results of this study and taking into account the growing trend of saline soils in the country, priming and application of chitosan elicitor as a biological agent that reduces the effects of salinity stress on hyssop are important.
