To elucidate a mechanistic basis for the reductions in chlorophyll (Chl) and inhibition of CO2 assimilation (ACO2 ) in nitrogen (N) starved citrus leaves, changes in Chl concentration and net gas exchange rates were examined together with chloroplast ultrastructure in N-deficient (125 mmol N m−2) and N-sufficient (286 mmol N m−2) citrus leaves. Two-year-old ‘Hamlin’ orange (Citrus sinensis L.) ...

This study was carried out in the Counties of Montenegro and Pareci Novo located in the region of the Vale do Rio Cai, Rio Grande do Sul, Southern Brazil, aiming to determine the fruit fly species of Tephritidae and Lonchaeidae that occur in organic orchards of sweet orange [Citrus sinensis (L.) Osb.] cultivar Céu, and Murcott tangor (Citrus reticulata Blanco x C. sinensis), during the fruit ri...

The benefits for human body are adds nutrients, minerals, other vitamin content because this made from real fruit juice. purpose study was to formulate with main ingredient swe...

Orange trees are widely cultivated in regions with high concentrations of tropospheric ozone. Citrus absorb ozone through their stomata and emit volatile organic compounds (VOC), which, together with soil emissions of NO, contribute to non-stomatal ozone removal. In a Valencia orange orchard in Exeter, California, we used fast sensors and eddy covariance to characterize water and ozone fluxes. ...

Volatile emissions of navel orange (Citrus sinensis L. Osbeck cv. Washington) fruit were evaluated as a means for predicting and gauging freeze damage. The fruits were subjected to -5 or -7 degrees C treatments in a laboratory freezer for various time periods of 2-9.5 h and stored at 23 degrees C for 1, 2, or 7 days, after which time the emission of volatiles from the fruit was measured. Follow...
