Physiological and anatomical response of rice ( Oryza sativa L.) ‘Hom Mali Daeng’ at different salinity stress levels
Soil salinity is a severe global stressor causing adverse impacts on irrigated land and drastically reducing crop yields, especially in rice, an important economic crop of Tailand. In this study, the impacts of salt stress on the anatomical and physiological features of 28-day-old rice ( Oryza sativ...

| description | Soil salinity is a severe global stressor causing adverse impacts on irrigated land and
drastically reducing crop yields, especially in rice, an important economic crop of
Tailand. In this study, the impacts of salt stress on the anatomical and physiological
features of 28-day-old rice ( Oryza sativa L.) ‘Hom Mali Daeng’ were determined.
Various NaCl concentrations (0, 50, 100, 150, and 200 mM) were applied every
2 days, with watering for 2 weeks. The results revealed that salinity stress inhibited
the growth of rice. Leaf number, root size, fresh weight, and dry weight were significantly
reduced. The electrolyte leakage percentage and malondialdehyde (MDA)
content increased after treatment with high NaCl concentrations, while the SPAD
unit and chlorophyll content were not significantly different between the control
and NaCl treatments. Leaf anatomy changes were studied using freehand section
and peeling techniques after salinity stress treatment. Lamina thickness in all treatments
decreased, while cell wall and cuticle thickness increased. Stomatal density
in all treatments significantly increased. Major vascular bundle, vessel, and phloem
area of the 100 mM NaCl treatment were different when compared with the control
and other treatments. The results provide information about the physiological and
anatomical adaptation of ‘Hom Mali Daeng’ rice, which will be useful for further
research in this and other rice cultivars. |
