Granulation in Florida Citrus
Granulation (also called crystallization or section drying) is a physiological disorder in citrus that results in reduced extractable juice and sometimes vesicle shriveling. While segments appear dry, the disorder is not caused by drying, but by gel formation within the vesicles. Though many citrus varieties may develop granulation (i.e., ‘Valencia’ orange, tangerines, and grapefruit), it was a...

متن کاملSeasonal Movement Patterns and Long-Range Dispersal of Asian Citrus Psyllid in Florida Citrus.
The Asian citrus psyllid, Diaphorina citri Kuwayama, is the vector of the bacterial pathogen, Candidatus Liberibacter asiaticus, which is the causal agent of huanglongbing (HLB) in the United States. Both short-range and long-range dispersal of D. citri adults affect the spread of HLB; however, little is known about the long-range dispersal capabilities of D. citri in the field or the seasonali...
