Flooding is one of the major abiotic stresses which accounts for considerable damage to plant growth and development and induces multiple morpho-physiological dysfunctions in many crop plants, including buckwheat. The present study aimed to elucidate the potential stage and duration of water logging treatment during the various stage that had the most severe effect on yield in common buckwheat (Fagopyrum esculentum cv. Harunoibuki). The plants were subjected to flooding stress during 3 days at ES, MS, and FS with 5 cm of water depth. The results showed that the plant height, SPAD (soil plant analysis development) value, chlorophyll fl uorescence, root analysis (length, surface area, and volume), and dry weight were found to be influenced when plants were exposed to flooding stress at each stage. Here it was demonstrated that root parameters were more impaired by flooding stress than shoot parameters. The fi ndings concluded that early growth stage was more sensitive regarding physiological characteristics (value of SPAD and chlorophyll fluorescence) and root morphology (root length, surface area, volume, and dry weight) under flooding stress in common buckwheat.
