Narrow Results

In order to control plant height and inhibit over growth, potted blueberry were treated with Chlorcholinchlorid (CCC) by spraying on the leaves, effects of CCC on the plant height, stem diameter, canopy width, pitch spread and leaf thickness were investigated. The results showed that optimum dwarfing treatment for blueberry was application CCC solutions of 300 mg/L or 600 mg/L, the effect was most accord with dwarfing objective of pot culture.

Blueberry fruits have a very short shelf-life period due to rapid loss of weight, senescence, and pathogen infection, which quickly causes the fruit to deteriorate. This study aimed to evaluate the effect of chitosan coating treatments on the quality attributes and the softening of blueberry fruits. Chitosan coatings at concentrations of 0.5 and 1.0% were applied to fresh blueberries before being stored at 4°C. Changes in quality characteristics and cell wall enzymatic activity were evaluated. Chitosan-coated blueberries lost less weight and had an increased firmness than the control group. The chitosan coating at 1.0% decreased the activity of cell wall hydrolase activities. These findings suggest that the use of 1.0% chitosan coating at cold temperatures is useful for slowing deterioration, maintaining quality and extending the shelf-life of blueberry fruits.
