Permite comparar el comportamiento de tres taxa de Pinus en los años 2013 y 2015. Se realizó la caracterización de sus conos a partir de sus dimensiones en ambos años, y se compararon los incrementos o decrementos en diámetro y longitud. Pinus engelmannii presentó un aumento en longitud de 17 mm y en diámetro de 19 mm; Pinus durangensis decreció 20 mm en longitud y aumentó 23 mm en diámetro. Pinus cooperi ganó 4 mm en longitud y 13 mm en diámetro. El tamaño del cono se relaciona con el potencial biológico y la producción de semilla (semillas desarrolladas, SD). En Pinus engelmannii el potencial biológico fue más alto en ambos años; Pinus durangensis y P. cooperi registraron un incremento de 2013 a 2015. Respecto a la producción de semillas (semillas desarrolladas, SD), no hubo diferencia significativa entre años Pinus engelmannii; Pinus cooperi y P. durangensis si se obtuvieron. La comparación de la producción de semilla en el género Pinus ayuda a conocer si existen diferencias significativas entre años de producción, áreas y especies, y así determinar que factores influyen en esa variación y como reducen la viabilidad y cantidad de semilla en los bosques.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: This comparative study reveals the biological potential and the production of seeds of superior trees. It allows to compare the behavior of three species in the years 2013 and 2015. The characterization of the cones was made by registering the dimensions of trees of each species in both years, comparing increases or decreases in diameter and length from 2013 to 2015. Pinus engelmannii showed an increase in length of 17 mm and an increase in diameter of 19 mm, Pinus durangensis decreased 20 mm in length and increased 23 mm in diameter, and Pinus cooperi grew 4 mm in length and 13 mm in diameter. The size of the cone is related to the biological potential and the production of seed (developed seeds, DS). The biological potential of Pinus engelmannii proved to be the highest in both years, the Pinus durangensis species registered an increase from 2013 to 2015 in the same sense as Pinus cooperi. In terms of the seed production variable (developed seeds, DS) the Pinus engelmannii species exhibited no significant difference from one year to the next; however, there were no significant differences in Pinus cooperi and P. durangensis between 2013 and 2015.]]></p></abstract>
