Abstract

In this work, some physiological parameters of micropropagated Bac Kan local alpinia (Alpinia coriandriodora D. Fang) affected by drought and salicylic acid treatments under drought condition were analyzed. In comparison to well watered plants, the droughted plants have lower contents of relative water, photosynthetic pigments, anthocyanins in leaves and Fv/Fm ratio. In constrat, proline content and activity of both catalase and peroxidase are higher in droughted plants. SA treatments, 10 M in particular, attenuate damages in droughted alpinia plants by affecting on some physiological parameters. An increase in content of relative water, photosynthetic pigments (chlorophylls and carotenoids), and anthocyanins were observed in leaves of treated plants in comparison to non-treated plants under drought condition. Fv/Fm ratio and peroxidase activity are higher in 10 M SA-treated plants than non-treated ones. Both 10 M and 100 M SA treatments lead to a decrease in proline accumulation and catalase activity in leaves of droughted plants.
