Comparison of Substrates in Sexual Propagation of the Quina Tree (Cinchona officinalis)
Overview
In the present investigation we compare eight types of substrates in sexual and asexual propagation C. officinalis in proportions (70% humus + 20% organic soil + sand 10%); ( 70% litter + 20% organic soil + 10% of sand); (70) % Frank sandy + twenty% of land organic +10 % of sand); (35% of humus + 35% of leaf matter + 20% land organic + 10% of sand); (35% of humus + 35% sandy loam + 20% organic soil + 10% sand); (35% litter + 35% sandy loam + 20% organic soil + 10% of sand); (25% of humus + 25% of leaf litter + 20% land organic + 10% sand); (25% humus + 25% litter + 25% sandy loam + 20% earth organic + 10% of sand), plus 1 witnesses in the sexual propagation the germination percentage of the seeds was evaluated , obtaining, that the T6 (35% of litter + 35% of sandy loam + 20% of organic earth and 10% of sand) reached the highest percentage of germination with 30%, reaching a height of 4.2 cm per plantlet at 60 days. While; in the asexual propagation was carried out: rooting trials of stakes, evaluating the number of buds, number of estate, length of roots per stake; reaching T6 the highest number of shoots per stake with 3 outbreaks; with a root length of 4 cm per stake planted. Keywords : Quina tree, sexual and asexual propagation
