the effects of mandarin scions on peel components and juice quality parameters were investigated in this study. peel flavor components were extracted by using cold-press and eluted by using n-hexane. then all analyzed by gc-fid and gc-ms. total soluble solids, total acids, ph value, ascorbic acid as well as density and ash were determined in juice obtained from mandarin scions. twenty-seven, tw...

optimal nutrition of grapevine is one of the most important factors that affect the quantity, quality and time of fruit ripening. to increase the quantity and quality of ‘askari’ cultivar, a factorial experiment in a randomized complete block design with three replications was conducted at shahrekord in 2010. treatments consisted of four levels of potassium sulfate fertilizer (zero, 300, 600 an...

BACKGROUND: The impact of organic and conventional production systems on quality and nutritional parameters of fruits and vegetables is still under discussion. The objective of this study is to determine whether the production system has a significant effect on the quality and nutritional content of one variety of processing tomatoes grown on a commercial scale by comparing three different grow...

In this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. Fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). Following treatments, fruits were stored at 0?C and 80 ? 2% relative humidity for 25 days. The weight loss, total soluble solids (TSS), titratable acidity (TA)...

INTRODUCTION Starch is the predominant carbon sink of storage organs and leaves of many plants. Substantial evidence from the analysis of starch-deficient mutants, transgenic plants, and enzyme kinetics suggest that ADP-glucose pyrophosphorylase (AGPase) catalyzes a key step for starch biosynthesis in both photosynthetic and nonphotosynthetic tissues. Fruit quality in tomato is largely a functi...
