Abstract
The wasabi was planted in glasshouse to investigate the effect shade level (0, 10, 30, 70%) on growth and photosynthetic response. The net photosynthetic rate and stomatal conductance were the highest under 10% shading rate in greenhouse. The lowest transpiration rate was in the non-shading treatment. 70% shading rate significantly reduced in photosynthetic characteristics. The number of leaf was decreased with increasing of shading rate. Leaf and petiole weight was the highest 10% shading and then followed by the non-shading treatment. Number of leaves, leaf, petiole and total weight were severely declined in 70% shading treatment. Shading rate (0%, 10%, and 30%) did not significantly influenced on the leaf length, leaf width and root growth. 10% shading level was the most effective for wasabi leaf production in hydroponics.
