In the regional trial of Hubei Province in 1991, its yield was 4.4% higher than that of the CK Weiyou 48-2, being significant at 0.05 level. In the same year, in another regional trial of Sichuan Province, its yield was 8.9% higher than that of the CK Weiyou 48-2, being significant at 0.01 level. It has the highest yield among all tested varieties in both provincial trials. It has shown good grain quality with 60% head rice recovery and moderate resistance to rice blast.展开更多

The sulfonic acid-functionalized nanoparticles were evaluated as catalysts for the synthesis of 5-aryl-1H-benzo[f]chromeno[2,3-d]pyrimidine-2,4(3H,5H)-dione derivatives in terms of activity and recyclability. Their catalytic activities were compared with that of the homogeneous acid catalyst 1-methylimidazolium hydrogen sulfate([HMIm][HSO4]). The activity of Fe3O4@MCM-48–SO3H was comparable to those of the other heter-ogeneous and homogeneous catalysts.展开更多
