THE GRAFT IN THE GROWTH AND STOMATIC DENSITY IN (Lycopersiconesculentum Mill) CULTIVATED IN SHADE MESH
El bajo rendimiento de un cultivo es el resultado de una serie de factores bióticos y abióticos que intervienen desde el crecimiento inicial, lo cual repercute de manera importante durante todas las etapas de desarrollo. Por eso, el Cambio Climático presente en la actualidad ejerce predominio sobre el desarrollo de las plantas, por ello es importante generar e implementar tecnología para afrontarlas. La producción de hortalizas, en especial el cultivo de tomate (Lycopersicon esculentum Mill.), ofrece una oportunidad de producción en la región sureste de México. Sin embargo la falta de tecnología y los altos costos de los insumos agrícolas ha inhibido la proyección de este cultivo. La técnica del injerto se presenta como una innovación para mejorar el potencial productivo de la planta bajo condiciones protegidas. El presente trabajo tuvo como objetivo estudiar el comportamiento del crecimiento del cultivo de tomate con técnica de injertación bajo condiciones de malla sombra. Las variedades utilizadas fueron Multifort (Portainjerto), el Cid (Injerto) y Enforcer, El Cid F1 (como testigo); durante el crecimiento se midieron las variables altura, diámetro, área foliar, fitomasa y la densidad estomática. Los resultados muestran que, el Injerto no influyó en la altura de la planta y diámetro del tallo; asimismo la fitomasa seca y la densidad estomática no presentaron diferencia significativa en el injerto. Sin embargo, el área foliar fue superior en el injerto en las dos etapas de muestreo.

Abstract:
The low yield of a crop is the result of a series of biotic and abiotic factors that intervene from the initial growth, which has an important impact during all stages of development. For this reason, the Climate Change present today has predominance over the development of the plants, for this reason it is important to generate and implement technology to face them. Vegetable production, especially tomato cultivation (Lycopersiconesculentum Mill.), offers a production opportunity in the southeastern region of Mexico. However, the lack of technology and the high costs of agricultural inputs have inhibited the projection of this crop. The grafting technique is presented as an innovation to improve the productive potential of the plant under protected conditions. The objective of this work was to study the growth behavior of the tomato crop with the grafting technique under shade mesh conditions. The varieties used were Multifort (Rootstock), El Cid (Graft) and Enforcer, El Cid F1 (as control); During growth, the variables height, diameter, leaf area, phytomas, and stomatal density were measured. The results show that the graft did not influence the height of the plant and the diameter of the stem; also dry phytomass and stomatal density did not show significant difference in the graft. However, the leaf area was higher in the graft in the two sampling stages.
