For orange juice (OJ) use, although sugars and acids are essential for good taste, it is the volatiles that in fact determine the unique flavor of a cultivar ( Shaw, 1991 ). The hybrids between mandarin and sweet orange and their descendants

schedules The experiment was conducted from 1 Jan. 2014 to 27 Aug. 2015 on 12-year-old sweet orange [ Citrus × sinensis (L.) Osbeck] trees located in three commercial groves: 1) Arcadia, FL (27.22°N, 81.86°W) in a valkaria fine sandy soil (Siliceous
‘Hamlin’ is the dominant early-maturing sweet orange [ Citrus ×sinensis (L.) Osbeck] variety in Florida, which is used mainly for juice processing. However, like other sweet oranges, ‘Hamlin’ has low resistance to Huanglongbing (HLB, also called
Sweet oranges [Citrus sinensis (L.) Osb.] are grown in many places throughout the world and are popular as fresh fruit, especially navel and ‘Valencia’ oranges ( Saunt, 2000 ). Sweet oranges are also grown for processing primarily in Florida and
