Seasonal changes in °Brix and °Brix/% acid ratio of Florida early season oranges and California 'Washington Navel' oranges were fitted by linear models. The constant term varied with different climatic conditions. The rate of Florida Agricultural Experiment Station Journal Series No. N-00240. Froc. Fla. State Hort. Soc. 103: 1990. change was 0.0256 °Brix/day and 0.0735 ratio/day for Florida ear...

A designed lightweight experimental shaker successfully used to collect ornamental oranges has been tested harvest fresh market citrus. The aim of this study was evaluate the removal efficiency and operational times device compared an orchard trunk shaker. Three different collecting systems were studied. ‘Caracara’ citrus trees tested. Removal efficiency, vibration parameters, fruit tree damage...

Citrus canker and Huanglongbing (HLB) are citrus diseases that represent a serious threat to the citrus production worldwide and may cause large economic losses. In this work, we combined fluorescence imaging spectroscopy (FIS) and a machine learning technique to discriminate between these diseases and other ordinary citrus conditions that may be present at citrus orchards, such as citrus scab ...

The main objective of this research was to design an efficient trash removal system and quantify the amount of trash materials such as leaves and twigs, generated during harvesting by a continuous citrus canopy shake and catch harvester, and to compare the efficiency of two destemmers with different lengths. A regular de-stemmer with a set of ten 24-inch long rollers and an extended de-stemmer ...

The profitability of fresh citrus crops outlines the possibility using mechanical systems to reduce high cost manual harvesting operation. In this line, an experimental light shaker with low frequency and amplitude a hydraulic arm was developed. This device had been successfully used for ornamental trees. previous studies, it proven that removal percentage adequate, but slightly damaged fruit i...

abstract in this study, the physicochemical quality and antioxidant activities of fruits peel from 6 citrus varieties which commonly consumed in the north of iran were determined. some parameters were measurement such fruit size, peel thickness, residue percentage, peel color indices, total phenolics, total flavonoid, total anthocyanins, total carotenoids, total chlorophyll, ascorbic acid conte...

Dehydrated citrus pulp and citrus pulp-protein supplements were evaluated as potential supplements for a preconditioning program. The supplements compared were no supplement, citrus pulp alone, citrus pulp with urea, and citrus pulp with added UIP. Supplemented cattle produced greater gains than unsupplemented cattle. Citrus pulp with added UIP produced the greatest ADG (0.95 lb/hd/d) whereas c...
