2009/7/7
Percentage of dying rachis branches and ripened grains of rice plant exposed to salty winds due to typhoon no. 15, 2004 in the Shonai area of Yamagata prefecture was investigated, to evaluate the eff...
Comparison of the Degree of Damage between Rice Plants Sprayed with Seawater and Exposed to Salty Wind Damage by the Typhoon No.15 in 2004
Sea water Artificial reproduction Rice yield Salty wind damage Amount of NaCl adhesion per panicle
2009/7/7
The decrease in the rice yield caused by salty winds is due to the increased amount of sodium (Na) adhered to panicles and leaves. The effect of the amount of Na adhered to plants on the yield of ric...
