Comparación de dos cortes y tres tipos de podas y su influencia en las características agronómicas de rosas

Abstract

In this investigation 20 genotypes of rose varieties with a broad spectrum of variability for different agronomic traits were evaluated in the greenhouse “The Capulin”, with an object of comparing two cuttings and three types or pruning and to study their influence on different agronomic characteristics, of indentify superior varieties of roses in quality and to study phenotypic correlations between different pairs of characters. 

The two cuttings and three prunings (ascent, descent and stipulate) were carried out when the genotypes were two years or growth. A randomized block design was used with factorial arrangement of three factors ABC namely A = Cutting (cutting 1 and cutting 2); B = Pruning (ascent, descent and stipulate); C = Varieties (20 genotypes). Data was recorded on ten characters. 

The analisis of variance showed significant differences for all the characters stud ied among genotypes. The differences were nonsignificant between three prunings. The two cuttings of rose flowers increased the values of the following characters: stem length, stem diameter, maternal stem diameter, floral arrangement and number of petals and increased the quality of flowers. The ascending pruncing was the best in the production of quality flowral stem. The varieties Marlises, Vivaldi, Liberty and Royalty were identified as superior for the majority of the characters studied.
