The capacity of honey to break light is used for refractometric determination humidity. In the present work, a manual refractometer was measure total soluble solids (73% - 86%) which are corresponding values refractive indices stated in Chataway’s Table. relationship between solids, water content and index obtained graphics gave equations that could be directly calculate both from its solids. T...

This study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-D and naphthalene acetamide application on yield and quality of date palm of ‘Kabkab’ cultivar. The inflorescences sprayed with 2, 4-D isopropylester (0, 10, and 20 mg L-1), naphthalene acetamide (0, 80, and 120 mg L-1), putrescence and spermidine (0, 0.1, and 1.0 mM), three or six weeks after pollin...
