Physico-Chemical Evaluation of the Natural Stability of Coconut Milk Emulsion

Oscar D. Monera and E. J. del Rosario ABSTRACT The stability of coconut milk emulsion against creaming at different pH levels was evaluated in terms of the concentration of oil, protein, total phosphorus and lipid phosphorus retained in the aqueous phase after a 6-hr standing. Better stability was generally observed in the pH regions where …

Effects of Drying Platform Elevation and Size of Meat on the Rate of Copra Drying

Aida C. Mantilla and Tung Ly ABSTRACT Among the different drying platform elevations tested (0.9 m, 1.08 m, 1.24 m), the 1.24 m elevation was found to produce copra of lowest moisture content when drying did not exceed 16 hr. The copra moisture content was not significantly affected by elevations when drying was prolonged to …

Growth and Survival of Containerized Moluccan Sau Seedlings Grown in Organic Containers

Manuel H. Reyes ABSTRACT Moluccan sau seedlings grown in coir dust container under green-house conditions performed better in terms of height, diameter, number of leaves and shoots than those grown from bagasse, rice straw and sawdust materials. However, in the field phase, rice straw container-grown seedlings attained the highest growth (height and stem diameter) six …

Inheritance of Resistance of Corn to Downy Mildew Caused by Perenosclerospora philippinensis (Weston) Shaw

Othello B. Capuno and Azucena L. Carpena ABSTRACT Evaluation of 36 entries for downy mildew reaction revealed significant differences due to location and genotype components; genotype-environment interaction was also detected. The interactions of general and specific combining ability components with locations were highly significant. The presence of partial or incomplete dominance governing the resistance of …

Elongation Response of IR-36 and RD-19 Rice Cultivars to Variation in Site of Naphthalic Anhydride and Thiobencarb Application

Rolinda L. Talatala ABSTRACT The effect of differential application of naphthalic anhydride or NA (1, 8-naphthalic anhydride) and thiobencarb (S-4-chlorobenzyl diethylthio-carbamate) in IR-36 and RD-19 rice seedlings was determined in pot trials under laboratory conditions. The two cultivars responded similarly to NA or thiobencarb treatment in terms of inhibited root growth when the site of …

Isolation and Characterization of the Insecticidal Fraction from Leaf Extracts of Thithonia diversifolia A. Gray

Ma. Flerida A. Carino and Belen Morallo-Rejesus ABSTRACT The different fractions of the acetone extract of Tithonia diversifolia A. Gray leaves were separated by preparative layer chromatography after precipitation of pigments and more polar constituents with lead acetate. The insecticidal fraction was identified through insect bio-assay using Dysclercus cingulatus Fab., Tribolium castaneum Herbsr. and Sitophilus …
