The results showed that calcium( Ca) spraying during young fruit period increased Ca and VCcontents in the fruit,improved SOD and POD activities,and declined K content,K/Ca and the occurrence of fruit cracking. When spraying calcium inhibitor during young fruit period,it aggravated fruit cracking.展开更多

The fractured surface was characterzed by cleavage fracture. The inhibiting effects of KI on SCC behavior were also covered in this detailed study which showed that they were meinly attributable to their inhibition on anodic reaction. The SCC mechanism study supported the unified mechanism of SCC and corrosion fatigue cracking (CFC).展开更多
