Valoración de dos medios de cultivo con adición de agua de coco y tres fotoperiodos en la germinación de semilla y desarrollo de protocormos de la orquídea cyrtochilum edwardii

Abstract

This investigation project took place in Ecuaflor-A laboratory, with the goal to contribute towards the rescue and conservation of an endangered species of orchid endemic to a zone of Molleturo (Cyrtochilum edwardii). That species of orchid was abundant years ago but due to the expansion of farming and its extraction due to commercial mean this plant has become depleted.The seed utilized for this project was inside a closed capsule, the same type of capsule was also used for the vitro cultivation.For thisto occur there were two house techniques based upon plantain and an apple, applied to three photo periods of time and four repetitions. This was made on an experimental design of blocks completed simultaneously; the results obtained were statistically analyzed median to the multiple ranks of Duncan to the 5%The variables in the project were the percentage of germination from the third week until the eleventh week and the formation of protocorms from the seventieth finalized on the ninetieth week.Throughout the investigation the technique of plantain with a photoperiod of 16 hours gave positive results of the germination of the seed and the formation of protocorms. Keywords: Cyrtochilum edwardii, cultivation techniques, photoperiods,in vitro culture.
