Moreover,prior to the respiration climacteric,the respiration rate of pre-harvest calcium treatment was lower than that of the post-harvest calcium treatment,however,with the prolongation of storage,the former was higher than the latter.

Effect of preharvest spraying chitosan on storage properties of litchi;

The experiments indicated that the integrated desulphurization technology of calcium spurt and water bath has a higher desulphurization effect than that of single spurt calcium process or the water bath possess,and calcium carbonate spurted can get fully utilization.

Research progress of FGD technology by limestone injection in pulverized-coal fired boilers;

Using Tongchuan coal with high sulfur content, experiments on SO_2 generation were performed in one-dimensional test rigs under both routine combustion as well as limestone injection conditions.

Study on Biochemistry Physiology of Lotus Before-Harvest and After-Harvest;

Changes of flesh firmness,respiration rate,ethylene production,cell wall hydralases(polygalacturonase,pectinmesterase,carboxymethl cellulosase) activities of muskmelon were studied in order to investigate the effect of both pre-harvest and post-harvest calcium treatments on fruit softening.
