Both low and high temperatures affect plant growth and development at whole plant level, tissue and even cell level through a variety of metabolic changes. In this paper we investigated the extent of the inhibition of growth, macro–element uptake and soluble carbohydrate production, and the effect of extra–supply of minerals as a means of the recovery from the damage. Lettuce plants were grown four different growth temperatures (15/8, 22/15, 25/18 and 28/21°C), and extra–supply of minerals was composed of 1.5– and 2.0–fold stronger than the standard nutrition (1/2 strength of Hoagland's solution). Low and high temperatures significantly adversely affected lettuce growth, mineral uptake and soluble carbohydrate production, and the extra–supply of minerals didn't play any crucial roles to promote and recover them. Merely, P uptake was slightly increased by an extra–supply of nutrients in all temperature conditions. From this study, it was strongly suggested that further research should include the effect of extra–supply of minerals when plants are recovered from low or high temperature stress, and metabolic interaction such as mineral uptake and carbohydrates between shoot and root.
