Carotenoids in the peel of harvested citrus in creased following treatment with ethylene. Im proved color resulted primarily from an increase in the amount of an orange-red pigment, cryptoxanthin, and a red pigment, jg-citraurin. Tempera ture influenced pigment accumulation. At 65 °F and 75 °F, rapid accumulation of both cryptoxanthin and jg-citraurin resulted in highly colored fruit. At 85 °F,...

the effects of rootstocks such as 'sour orange' (citrus aurantium l. var. ‘yerli’), 'carrizo' and 'troyer citranges' (citrus sinensis osb. x poncirus trifoliata raf), 'smooth flat seville sour orange' (citrus spp. hybrid of uncertain origin), 'brazilian sour orange' (citrus aurantiam l. var. ‘brasilian’), 'volkameriana' (citrus volkameriana tan. and pasq.) and 'calamondin' (possibly citrus reti...

In an earlier study, an electronic tongue system (e-tongue) has been used to differentiate between orange juice made from healthy fruit and from fruit affected by the citrus greening or Huanglongbing (HLB) disease. This study investigated the reaction of an e-tongue system to the main chemicals in orange juice that impact flavor and health benefits and are also impacted by HLB. Orange juice was...

The economic viability of employing dark fermentative hydrogen from whole fruit wastes as a green alternative to fossil fuels is limited by low hydrogen yield due to the inhibitory effect of some metabolites in the fermentation medium. In exploring means of increasing hydrogen production from fruit wastes, including orange, apple, banana, grape and melon, the present study assessed the hydrogen...

The relationship between carotenoid accumulation and the expression of carotenoid biosynthetic genes during fruit maturation was investigated in three citrus varieties, Satsuma mandarin (Citrus unshiu Marc.), Valencia orange (Citrus sinensis Osbeck), and Lisbon lemon (Citrus limon Burm.f.). We cloned the cDNAs for phytoene synthase (CitPSY), phytoene desaturase (CitPDS), zeta-carotene (car) des...

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...

opiine braconid parasitoids of tephritid pests have augmentative biological control potential, but there are no synthetic attractants to monitor their survival and dispersal following release. adults feed on fruit juices and these could be sources of attractive compounds. While orange juice (Citrus sinensis l.) is nutritious, guava juice (Psidium guajava l.) is toxic. the behavioral responses t...

Health system reforms and health system comparisons have been popular topics of discussion for the policy and research communities. Yet, there is no clear concept and definition for a health system. As a result, comparisons are often made between apples and oranges, resulting in confused discourses and misleading conclusions. This paper argues that for policy and economic research purposes, it ...
