The Effects of Salinity and Methyl Jasmonate on Morphological and Biochemical Characteristics and Photosynthetic Pigments Content in Two Basil Cultivars

Abstract:   (295 Views)

To evaluate the interaction effects of salinity and methyl jasmonate on some morphological and biochemical characteristics of two cultivars of basil, a pot experemint was carried out using factors of salinity (0, 30, 60 and 90 mM) and spraying methyl jasmonate (0, 5.0 mM) in two commercial cultivars (Rubi and Genove). The results showed that salt treatments had a significant effect on all traits, except the content of carotenoids. With increasing salinity levels up to 90 mM plant height, shoot dry weight, total carbohydrates and relative water content in both cultivars decreased, whereas the weight of the root, electrolyte leakage, proline, chlorophyll a and total chlorophyll increased. Methyl jasmonate treatment had a significant effect at 1% level of probability on stem fresh weight, total carbohydrates, prolin and total chlorophyll, and at 5% level of probability on plant height, root fresh and dry weight and chlorophyll a and b, but it was ineffective on other characteristics. The interaction effect of salinity × methyl jasmonate was significant on chlorophyll a and b and total chlorophyll (P≥ 0.01) and interaction effect of salinity × methyl jasmonate × cultivar was significant on root fresh weight, total carbohydrates, chlorophyll a and total chlorophyll (P≥ 0.01), but it was ineffective on other traits. The overall results of this study showed that cultivars of basil had different response to salt stress and use of methyl jasmonate. The application of methyl jasmonate in stress condition improved charactrestics of morphological, biochemical and photosynthetic pigments in the basil.
