Abstract

An experiment was conducted at the Agricultural Research Center of Al Ghab, General Commission for Scientific Agricultural Research (GCSAR), Syria, to evaluate the effect of slaked lime application on the sugar losses reduction, and some quality traitsin2014/2015 season. Four slaked lime concentrations of 0, 5, 10 and 15 percent (factor C) and storage durations of 6 days (factor D) and tow varieties (Factor V) were arranged as factorial experiment in RCBD with four replications. The varieties one of them was monogerm (Vico), while the other was multigerm (Reda), they were drilled in mid November, and storage roots were harvested late August. Weight percent loss and quality of beet samples such as sugar content, total soluble solids (TSS%), and purity% were determined throughout storage period. The results of analysis of variance ANOVA showed that effect of varieties was significant for TSS (brix%), sucrose%, root weight loss (P<0.05).All the studied traits were affected significantly (P<0.05) by storage duration. Lime concentration had significant effect only on sucrose% (P<0.05).There was no interaction between lime concentration and storage duration for all studied traits, but for sucrose%. The percentage of variance confirmed that the most effective factor for the all studied traits was the storage period, followed by the varieties, and finally in a very low percent was the chemical treatments, because of that it is very urgent to send the harvested roots immediately to the factories to be processed within 24 hours.
