"Assessment of Genetic Diversity in Garcinia Species by using Isozyme Analysis, Random Amplified Polymorphic DNA (RAPD), and Simple Sequence Repeats (SSRs)"
Genetic diversity in 22 accessions of Garcinia species was assessed using isozyme analysis, random amplified polymorphic DNA (RAPD), and simple sequence repeats (SSRs). Among the 15 isozymes tested, only peroxidase isozyme produced bands. A...

Mites pass through egg, larval, protonymph, and deutonymph stages reaching the adult stage. Average duration (in days) of the life stages for female and male Tetranychus uricae were incubation period, 3.43+0.11 and 3.63+0.11; larva, 1.70+0.24...

The study was conducted to estimate the heritability of and correlation among semen characteristics and reproductive traits in various genetic groups of Mallard ducks (Philippine Mallard, Pekin, and Khaki Campbell). More specifically, the study aimed... Read more.MS in Animal Science (University of the Philippines Los Baños)"In Vitro Propagation and Mutation Induction of Dendranthema grandiflora Tzvelev"
The genus Dendranthema (Family: Asteraceae) is a popular cut flower or pot plant species of high economic value cultivated around the world. The genus has more than 100 species of annual and perennial herbs and shrubs used as floral crops as...

The study analyzed the nature of institutional transformations (ITs) of agricultural cooperatives (ACs) in response to agricultural industrialization (AI) and their contributions to development of the community. Proportional random sampling was used... Read more.PhD in Community Development (University of the Philippines Los Baños)"Isolation, Purification, and Characterization of a Lectin from Synapta sp"
A survey was conducted on 32 species of marine invertebrates collected in three Philippine provinces; namely, Leyte, Samar, and Batangas, as source of lectin. Among the non-food invertebrates, Synapta sp., class Holothuriodea, family...
