Caracterización del tejido fundamental bajo el efecto de un factor altitudinal en la primera parte de la curva sigmoidea del crecimiento del fruto del durazno de la variedad Amarillo Jarillo.

Abstract

The peach, P persica (L.) Batsch, belongs to the family Rosacea, native to Asia, specifically China. In the sixteenth century it was in Mexico, brought by the Spaniards, and were introduced to Colombia in the colony by the Spanish, so it is strongly linked to the country's agricultural history. To the north of Santander is a crop with high profitability and importance for the economy and stability in farming families as it has grown in recent years in terms of hectares planted, and you can place north Santander department in the first place the country, not only planted area but also for productivity per plant (Peñaranda, 2013). This work was performed in order to establish the differences in the underlying tissues, adaxial epidermis, abaxial in this species, Yellow peach variety Jarillo. Together with the assessment of phenotypic plasticity and the percentage of each tissue for different altitudes. Was obtained for the portion of phenotypic plasticity tissue had significant differences when (p <0.05) based on the multiple comparison test of Tukey was the adaxial and abaxial epidermis, in terms of percentages of the fundamental fabric and adaxial epidermis it was obtained that Pamplonita for height and Chitagá the percentage of palisade and spongy parenchyma was the largest with respect to Pamplona.
