GARCIA ENCISO, Ema Laura; ROSA IBARRA, Manuel De La; QUEZADA MARTIN, María del Rosario y ARELLANO GARCIA, Marco Antonio. Effect of a plastic film modified in agronomic aspects of tomato (Solanum lycopersicum L.). Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe11, pp.2105-2113.

The aim was to study the effect of a modified cover for greenhouse (CIQA) in some agronomic traits of tomato plants. The work was conducted at the Center for Research in Applied Chemistry in Saltillo Coahuila, Mexico in 2013. Greenhouses were set, one with the conventional film and the other with the modified film, the photosynthetically active radiation (PAR) was measured and the temperature inside and outside of greenhouses. A tomato crop was established and, the stem diameter, height, leaf area and biomass accumulation in seven dates during the growing season was determined, fruit size and yield were also determined. The maximum PAR readings were higher abroad, then the conventional greenhouse and finally in the greenhouse CIQA. As for temperature, the highest readings were made in the conventional plastic greenhouse, followed by CIQA and abroad. Differences in height in two sampling dates, in the first sampling as high as the obtained plants under the film CIQA with 54.33 cm and 47.33 with the conventional film, for the fifth sampling height was 252.66 cm in plants under conventional plastic and 231.66 cm for plants with plastic CIQA. This leads to the conclusion that the plastic film CIQA decreases radiation and temperature inside the greenhouse, which does not affect agronomic parameters of tomato plants.
