Abstract

The research internship was conducted in the Tissue Culture Facility (TCF) and Ornamental Crop Nursery (OCN) of the Crop Science Cluster and in Host Pathogen Interaction Laboratory of the Crop Protection Cluster, University of the Philippines Los Baños, Laguna from May 2014 to June 2015. The internship included the salicylic acid-treatment of Cymbidium mosaic potexvirus-infected Mokara protocorms and the translocation of the said virus on Dendrobium UH hybrid. The treatment of varying concentrations salicylic acid (0 mg/L, 8 mg/L, 16 mg/L and 32 mg/L) in the culture medium resulted to minimal effects on the induction of systemic virus resistance to the protocorms. Five (5) percent efficacy at thirty days post-inoculation was achieved from the culture medium supplemented with 32 mg/L salicylic acid. However, inhibition of growth and multiplication of the explants were also observed at this concentration of the plant hormone. In another experiment, the systemic infection of native and cultivated Cymbidium mosaic potexvirus in Dendrobium UH was observed as soon as twenty one days after the rub-cut inoculation.
