During World War II, Velasco conducted research on the photoperiodism of the rice plant. Among his findings, which were published only after the end of the war, was that the Elon-elon variety flowered during short days when there was less than 12 hours of light.Velasco was skeptical of the still-prevalent view that the disease was viral in nature, and devoted considerable effort to prove his thesis that it was caused by an element in the soil that was toxic to the coconut plant. - WIKI
