Abstract
El presente trabajo de investigación se realizó en la empresa Viveros Génesis SAC. El objetivo del experimento fue determinar el efecto de diferentes tratamientos de termoterapia para control del hongo Cylindrocarpon sp, en el brotamiento y crecimiento inicial de ‘Thompson Seedles’ injertado sobre los patrones ‘Salt Creek’, ‘Freedom’ y ‘MGT’. Los tratamientos de termoterapia, aplicados a los patrones antes del injerto, fueron 30, 40 y 50 °C a 20, 30 y 40 minutos. Los promedios de los tratamientos fueron sometidos a prueba de t a un nivel de significación de 5%. El mayor porcentaje de brotamiento en ‘Salt Creek’ (92%) se obtuvo con la termoterapia de 50° y 20 minutos, en ‘Freedom’ (95.7%) fue con el tratamiento de 40°C y 40 minutos y en ‘MGT’ (98%) fue con 50°C y 40’. La altura de planta y la longitud del antepenúltimo nudo fue superior en los tratamientos con mayor brotamiento en ‘Salt Creek’ y ‘Freedom’ e igual en los injertos con ‘MGT’.
ABSTRACT This research work was carried out at Viveros Génesis SAC. The goal of the trial was to determine the effect of several thermotherapy treatments for control of Cylindrocarpon sp, on sprouting and initial growth of ‘Thompson Seedles’ scion grafted on ‘Salt Creek’, ‘Freedom’ and ‘MGT’ rootstock. Thermotherapy treatments applied to rootstocks, before grafting, were 30, 40 and 50 °C for 20, 30 and 40 minutes each one. Means of treatments were compared by student´s t-test at 5% significance level. Highest percentage of sprouting in ‘Salt Creek’ (92%) was got with 50 ° 20 minutes, in ‘Freedom’ (95.7%) with 40 °C 40 minutes and in ‘MGT’ (98%) was with 50 ° C 40 minutes. Plant height and antepenultimate node length were greatest in treatments with greatest sprouting in ‘Salt Creek’ and ‘Freedom’ while was the same in ‘MGT’.
