EFFECTS OF LIGHT INTENSITY, CO₂ CONCENTRATION AND LEAF TEMPERATURE ON GAS EXCHANGE OF STRAWBERRY PLANTS – FEASIBILITY STUDIES ON CO₂ ENRICHMENT IN JAPANESE CONDITIONS

Carbon dioxide enrichment to increase yields is a common practice for horticultural crops in cool climates.
Japan produces 85% of its strawberry crop under large plastic tunnels, winter through spring.
Therefore, the application of CO₂ at high concentration for strawberry production under these conditions seems to be a practical technique, but is not widely used at present.

In this report, we discuss the feasibilty of CO₂ enrichment for strawberry production under Japanese conditions, based on the results of experiments on morphological and physiological studies of stomata, gas exchange in relation to environmental factors, and survey data of the environment inside low and large plastic tunnels.
