The levels of free, perchloric acid-soluble conjugated and perchloric acid-insoluble bound polyamines were determined in pericarp and seeds of `Muscat Bailey A' grapes (Vitis labrusca L. Vitis vinifera L.) during development and ripening. In both, the pericarp and seeds, putrescine was the predominant polyamine in the three fractions, and the bound polyamine level was the highest of the fractio...

This study evaluated the effects of four different gibberellin-pastes (GAP) on fruit quality and storability niitaka pear in 2014 2015 consecutive years. Pear stalks were treated with dongbu GA gold, nebaekeo, busa, hyeophwa-pastes at 35 37 days after full bloom, respectively. After harvest time, fruits stored 0°C for up to 180 days. In both years, weight was 6.2-21.3% higher GAP-treated than c...

The effects of preharvest calcium chloride (CaCl2) treatment on some quality characteristics and bioactive compounds sweet cherry fruit (Prunus avium L. cvs. 0900 Ziraat, Sweetheart Merton Late) were investigated. CaCl2 (1%) solution was sprayed to the trees at 21 35 days after full bloom stage. served as control treated with distilled water same days. remarkably suppressed respiration rate inc...

By Zahi Kanaan-Atallah, Ph.D. Washington State University May 2003 Chair: Dennis A. Johnson Sclerotinia sclerotiorum (Lib.) de Bary is a cosmopolitan, homothallic and necrotrophic ascomycetous fungus dispersed by airborne ascospores and soilborne sclerotia. It causes disease in over 400 host species. A significant correlation between potato yield losses and stem rot incidence has not been obser...

Humic acids are the most active components of soil organic matter and have been shown to have an hormone-like activity thus stimulating plant growth. The objective of this work was to verify the quantitative and qualitative yield responses of the table grape cv. Italia after the application of a humic acid at various phenological stages. The humic acid used in this study has been extracted from...
