Studies on Palatability of Rice in Northern Kyushu : VI. Effect of seedling characteristics under abnormal weather in 1993 on the palatability and physicochemical characteristics of rice

[摘要] Under the low air temperature and the insufficient solar radiation conditions in 1993, the effect of seedling characteristics on the palatability and physicochemical characteristics of rice were studied. The values of overall eating quality rice from 3-4 leaved age seedlings were better than young seedlings. The good palatability rice from 3-4 leaved age seedling showed that palatability amelioration could be attributed to the lower protein and amylose contents and higher maximum viscosity and breakdown values. It was concluded that the differences in the palatability and physicochemical characteristics of rice from 3-4 leaved age and young seedlings were caused by the differences in air temperature during the ripening period and by the extent of grain filling, which was closely related to full heading.
