Abstract
This study examined the possibility of reducing the heat injury of spinach incurred by the roots. In the first experiment, spinach plants (Spinacia oleracea L. cv. Okame) were controlled or subjected to salt stress by adding 43mM NaCl to 30°C nutrient solution for 11 days. In the second experiment, plants were grown in three different concentration of salt (control, 43mM, 130mM) or PEG (29gl-1) treatments each for 2 days at 34°C. In the first experiment, at 30°C solution temperature, root weight of 43mM NaCl treatment was larger than that of control, while at 20°C solution temperature, the weight was almost same between the treatments. In the second experiment, 43 mM NaCl treatment increased shoot and root weights compared to those of control. However, 130mM treatment as well as PEG treatment did not show any positive effect on growth. The results indicate that addition of 43mM NaCl could reduce the heat injury of spinach root under high nutrient solution temperatures.
