| Descripción : | The present work of titration studied the phenological development of the reproductive stage of three varieties of the melloco crop (Ullucus tuberosum), which was carried out at the experimental farm Santa Catalina of INIAP located in the Mejía canton. The three accessions of the melloco culture were followed with the codes TM-2134, TM-2351 and TM-8493, together with the taking of photographic evidence from the appearance of the latent bud until the formation of the product. It became that the inflorescence of the melloco is of the indefinite cluster type with a monopodial rachis that transports pedicelled flowers, while the flower consists of: a perigonium with 5 tepals, 5 filaments with their respective anthers with two thecae and in the middle the structure gynecium. With the help of the BBCH scale each step of reproductive development is coded, resulting in: dormant bud (501), bloated flower buds (503), bloated bloated flower buds (507), separate bloated flower buds (509), first flowers open (601), 60 percent of open flowers of the inflorescence (606), 100 percent of the open flowers of the inflorescence (609) and fruit formation (700). The result obtained was that the TM-2134 variety obtained a previous development of the reproductive stage with a lapse of 48 days with accumulated 574.70 UT. The variety TM-2351 presented the total formation of the inflorescence in 66 days, accumulating 830.25 UT. In the TM-8493 variety it showed a late appearance of the reproductive stage, lasting 64 days accumulating a total of 795.84 UT to obtain 100 percent of the open flowers. Unfortunately, the fruit and seed were not visualized due to the fall of the flowers because it was affected by internal and external factors. |
