Entomology and Citrus Fruit Production

Floral Nutrients and Citrus Fruit Quality

Characterization of abscisic Acid-induced ethylene production in citrus leaf and tomato fruit tissues.

Abscisic acid (ABA) significantly stimulated ethylene production in citrus (Citrus sinensis [L.] Osbeck, cv Shamouti orange) leaf discs. The extent of stimulation was dependent upon the concentration of ABA (0.1-1 milimolar) and the duration of treatment (15-300 minutes). Aging the discs before applying ABA increased ABA-induced ethylene production due to enhancement of both ethylene-forming en...

High Application Rates of Reclaimed Water Benefit Citrus Tree Growth and Fruit Production

Conversion of wastewater to reclaimed water for crop irrigation conserves water and is an effective way to handle a growing urban problem: the disposal of wastewater. Water Conserv II is a large reclaimed water project developed by Orlando and Orange County, Fla., that presently irrigates ≈1900 ha of citrus. The project includes a research component to evaluate the response of citrus to irrigat...

Influence of Gamma Irradiation on Seedless Citrus Production: Pollen Germination and Fruit Quality

Seedlessness is a desirable characteristic in citrus fruits sold for fresh consumption. Gamma irradiation is widely used to obtain seedless citrus fruits. Here, different clones of the self-incompatible parthenocarpic “Moncada” mandarin, obtained by gamma irradiation, were studied to assess seedlessness, pollen germination, fruit characteristics and quality attributes. Findings indicate that ir...
