‘Fukumoto’ navel orange budwood was introduced into California from Japan by Glenn Dale of the United States Department of Agriculture (USDA) in 1983 (www.citrusvariety.ucr.edu). Fukumoto has many desirable attributes. It matures early (late October), typically three to four weeks earlier than Washington navel, it has deep reddish rind color that makes it highly desirable for packinghouse proce...

To deal with the incident, and guarantee the quality safety of navel orange, traceability system are used to record the information from tree planting to fruit sale. Navel orange safety production information management system, which manages the whole process from tree planting to circulation, achieves the entire information management except sale step of the navel orange food chain, is the cor...

Factors that influenced the increase in epiphytic bacterial population size on navel orange leaves during winter months were investigated to test the assumption that such populations were the result of multiplication on orange leaves. The population sizes of bacteria of different kinds, including ice nucleation-active (Ice(sup+)) bacteria, were from 6- to 30-fold larger on leaves of navel orang...

Understanding the spectral features of Washington navel trees is important to remotely measure and monitor the canopy properties and biochemical changes in plantations. Satellite and ground based passive remote sensing techniques have been widely used in many plant species. However, the use of these techniques in orange trees is limited. In this study, relationships between total chlorophyll (C...

The levels of abscisic acid (ABA) and alkaline-hydrolyzable ABAconjugate (putatively identified as the glucosyl ester, abscisyl-,8-D-glucopyranoside) were determined by enzyme immunoassay in the organs of developing navel orange (Citrus sinensis [L.] Osbeck cv Washington) flowers. Although both compounds were detected in every tissue, developmentally related differences between organs in the to...

abstract antioxidant capacity and quality of fruits usually changed during storage. in the current study, the changes of antioxidant capacity and postharvest quality of two blood (pigmented) orange cultivars (‘tarocco’ and ‘morro’) and ‘thompson navel’ orange, after 60 days storage at 7ºc and 90 rh% was investigated. during fruit storage weight loss, tss, ta, tss/ta, vitamin c, total phenol, an...
