Waterlogging period duration and temperature effects on glycolytic-fermentative enzymes activity in wheat seedling

Water logging stress has high destroyer effect on quality and quantity of crop production. This experiment was carried out to investigate alcohol dehydrogenize (ADH) and fructose- 1,6- bisphosphate aldolase (FBPaldolase) activities in wheat leaf (N8019) in vegetative growth stage (4-5 leaved) under water logging duration effects in different temperature in the form of combined analysis design with CRD arrangement in 4 levels of water logging period (0, 24, 48 and 96 hour) and 3 levels of temperature (5, 10 and 20 ˚C) in tetraplicates. The results indicated that the effects temperature and water logging duration and their interaction were significant on ADH and FBPaldolase activities at 1 % level. With increasing water logging period, ADH and FBPaldolase activities increased in 5 and 10ºC. Under 20ºC, both enzyme activities increased until 48h of water logging but both enzyme activities increased significantly when water logging duration increased up to 96 h.
