Abstract

Abstract. This study aimed to discover the response of Thalassia hemprichii due to high temperature stress treatment (40.5°C). Morphological and anatomical changes of leaf, rhizome and root, and chlorophylls content were investigated. The results showed that morphological changes were organ damage, changes of colors and texture. Anatomical changes were indicated by changes in leaf thickness, size of epidermis and mesophyll tissues in leaf; size of pith, cortex and aerenchyma tissues in rhizome; pith and aerenchyma tissues of root. While the cortex and endodermis tissues of the root did not show any changes. Chlorophyll a, chlorophyll b and total chlorophyll contents significantly declined due to heat stress.
