Morfología y análisis de la calidad de la semilla frailejón de la especie Espeletia Brassicoidea Cuatrec.

Abstract

The Colombian páramos, considered strategic and biodiverse ecosystems that offer multiple environmental and hydrological benefits, are threatened by the reduction of their plant population. In particular, the frailejones are displaced by crops or agricultural activities. The genus "Espeletia" is notably affected by external factors in its reproductive conditions, low germination in the field, high periods of seed dormancy and its slow and fragile development. To help reduce the problems that this genus has in its development, it is important to study in depth this species of "Espeletia brassicoidea" since it is found in the red book of plant species in danger of extinction. morphology of the plant, fruit and seed, where we can visualize and identify their part knowing this species in depth. Establishing three states of maturation of the floral chapters of this species, likewise three states of maturation of fruits and seeds are established. Carrying out physiological tests on the seeds to determine their vigor. Carrying out a BBCH scale where it is possible to establish protocols for the identification of seeds with an adequate physiological maturity for their germination. Identification of the pest insect in the seeds of "Espeletia brassicoidea" damage caused to the internal structure of the seed, these damages are another factor for which this species has a low percentage of germination. evaluating the behavior of the seeds in four traditional c-type substrates in the field and carrying out quality and vigor tests in the laboratory in two treatments at controlled temperature.
