Abstract Grapes are important sources of phenolics, which recognized to possess high biological value. In this work, we evaluated the total phenol content (TPC), anthocyanin (TAC), antioxidant activity (AA) and volatile composition unstudied seedless table grape varieties (i.e., Autumn Crisp Pristine as white cultivars, Scarlotta Crimson red cultivars Adora Melody black cultivars). As a result,...

Berry color is one of the main fruit attributes that affect the marketability of Thompson seedless grapes. Yellowish berries are more desired by consumers especially at the beginning of the season. Consumers in many European countries have been demanding yellowish berries of “Thompson” seedless grapes. Ethrel was found to enhance the breakdown of chlorophylls and the formation of carotenes. How...

(ibl)berellinl-like stulstances occtlr in mianv higher pllants (1 2, 17, 20). and sexeral have beenl idenitified (12). Tlhe presence of gibberelliln-like activity in seedless fruit, of V'itis v'iiifcra L. was (lenlonstrated in 1960 by Coombe (1). Although it seemiis probable that sulch a widely spread hormonie also would be invxolved in the groxwth of seede(d fruit, Coombe was unable to demnons...

Determining the harvest date of table grapes is very important to achieve high-quality bunches with adequate soluble solids content, low titratable acidity, and high concentrations polyphenols. Table grape consumption has increased worldwide due its phenolic compound content beneficial effects on human health. Thus, this study aimed characterize ripening ‘BRS Vitoria’ seedless at different stag...

The spider Latrodectus hesperus Chamberlin & Ivie (Araneae: Theridiidae) was subjected to low and ultralow oxygen (ULO) treatments at different temperatures. Complete control of the spiders was achieved in 24-h ULO treatments with 0.5% O2 or lower at 1 degrees C and in a 24-h low oxygen (2%) treatment at 15 degrees C. Oxygen level and temperature greatly affected spider mortality. At 1 degrees ...
