Title: Dynamic Studies on Grain Filling of Japonic Rice under Saline-Sodic Stress
Abstract: The Japonica rice cultivar DD4 and strain G19 were grown under saline-sodic stress on rice paddy with pH 8.01 and 9.03,respectively.The effects of saline-sodic stress on the dynamic changes of grain dry matter accumulation,milking rate and water content during rice milking stage were studied under the same conditions.The results showed that starting of the rice filling delays 5 days under severe saline-sodic stress;The superior grains are superior on dry matter accumulation to inferior grains,strong milking rate during former stage and downtrend later;The peak of dry matter accumulation DD4 is earlier than G19,and the times of milking peak of G19 superior grains are more than DD4.Water loss of DD4 is faster to both superior and inferior grains,and in this respect,G19 superior grains are the same whereas inferior grains exhibit slower water loss comparatively.
