Respuesta de Carludovica palmata a diferentes intensidades de cosecha de hojas
Two tests were established to determine the effects of harvesting new (spear) leaves in a natural population of C. palmata, a non timber forest resource used as a handicraft fiber. In the first test, two harvest intensities (0 and 100 percent of spear leaves) in plants from five size categories (based on number of shoots per cluster) were practiced. In the second test, three harvest levels (0, 50 and 100 percent) in plants from one size category were practiced. These treatments were conducted monthly during a period of eight months. The effects of the treatments on the growing and fruiting of the plants, production and dimensions of new spear leaves were evaluated. There were significant differences from basal cluster perimeter, petiole length, number of old leaves and spear leaves dimensions between plant size categories. During the eight months of sampling in the second test, there was a significant effect of the treatments on number of old leaves (less in harvested plants than in untouched plants), and number of fruits (more in harvested plants). In the first test, there was a significant effect on number of old leaves. The treatments did not have significant effects on the time of emergency, production and dimension of new leaves. It is suspected that cluster had sufficient reserves to replace the losses of leaf area caused by harvest during the test period. The highest fruit production was from February to April; up to 23 infrutescenses per plant in March, decreasing to the lowest point in August with 0.2 infrutescenses per plant. Greatest leaf production was when less fruits were present and the lowest was before April. It is recommended that leaf harvest should be done during the months of June to September, during the highest leaf production and to harvest bigger individuals.
