Lemuel M. Diamante ABSTRACT The moisture adsorption isotherms of tapahan dried copra were determined at 22, 30 and 38°C. The isotherm of copra at different temperatures were of type III according to the BET classification. Equilibrium moisture content of copra at a given water activity increased as temperature decreased. The Henderson equation gave better fit …

Marilyn Z. Oracion ABSTRACT The somatic chromosome numbers (2n) in seven sweetpotato cultivars, four diploid (2x) Ipomoea species, tetraploid (4x) and hexaploid (6x) I. trifida strains, and twenty selected hybrids between sweetpotato and 6x l. Trifida were determined using a Fealgen-acetocarmine squash technique designed for Ipomoea chromosomes. The data revealed that euploid counts of 2n=30, …
