【 摘 要 】

The effects of salty wind on the brown rice weight and quality of rice were investigated using a wind tunnel. Two varieties, cv. Hinohikari, cv. Yumehikari, were grown in 1/2000a Wagner's pots containing paddy field soil. The brown rice weight of a plot (non-salty water and non-water sprinkling) was 36.2 g/plant, D and H plots (weak wing treatment; 7.1±1.6 m/s, strong wind treatment; 14.4±4.3 m/s) with salty water treatment were 11.0 g/plant, 15.0 g/plant, respectively and under the condition of 60l/40 min water sprinkling treatment after salty water treatment were 21.7∼22.1 g/plant. The effects of salty water, water sprinkling, wind speed and treatment time on brown rice weight and 1000 grain weight were analyzed by the type I quantification method. According to the result of analysis of salty water treatment of brown rice weight, category scores were 6.47 and -9.71, and the partial correlation was 0.949. On the other hand, with water sprinkling treatment on brown rice weight, category scores were -1.87 and 2.81, and the partial correlation was 0.655. However, the partial correlation of wind speed or treatment time with brown rice weight was low.
