- Abstract
The extensive yam crop development has been limited, among other things, due to the limited availability of planting material with physiological and sanitary quality. Sometimes, multiplication rates are very low, so this work was developed in order to determine the influence of support height (2,0 and 2,50 m high) on aerial bulbils production in clones "Belep" and "Irat-72". Results obtained showed that "Belep" genotype showed the highest bulbils number per plant in all tested treatments, with significant differences in relation to "Irat -72" genotype. In "Belep" genotype, a higher bulbil production was obtained in treatments with supports from 1.50 to 2.50 m high. For "Irat-72" genotype a higher bulbil number was observed at 2.0 m high. In both genotypes, bulbil production decreased at a meter high. In the bulbil weight evaluation at different support heights, no statistical differences were noticed between evaluated genotypes. In "Belep" genotype, there was greater bulbil weight at 1.0 meter high, but "Irat 72" genotype did not show any statistical differences between evaluated treatments.
