          Abstract

          Se compararon los efectos del paclobutrazol (PBZ) y del tiempo de almacenamiento en frío de los bulbos (TA) sobre características comerciales de tulipán Tulipa gesneriana L. (Leen van der Mark) en maceta. Se evaluaron las concentraciones de PBZ: 0 y 5 ppm aplicadas por inmersión de bulbos durante 24 horas, previo al transplante, y los TA a 5 °C: 5, 6, 7, 8, 9, 10, 11 y 12 semanas. La temperatura promedio del aire de los ocho ciclos fue: 15 a 15,7 °C. El PBZ no afectó la longitud del ciclo, y los TA explicaron el 83% de la variabilidad en la duración del período transplante- momento de la venta, con una relación inversa. El PBZ no afectó el tamaño de la flor. La altura en el momento de la venta y a fin de floración mostró interacción de los tratamientos: a mayor TA aumentó la altura en todos los casos, pero este incremento fue menor en las plantas tratadas con PBZ. Sin utilizar PBZ y con bulbos de 5 a 8 semanas de almacenamiento fue posible producir plantas comerciales de altura equivalente o menor a las obtenidas con bulbos de 12 semanas de almacenamiento tratados con PBZ a 5 ppm por inmersión durante 24 horas.

          Translated abstract

          The effect of bulb cold storage time (ST) and paclobutrazol (PBZ) on commercial characteristics of pot tulips Tulipa gesneriana L. (Leen van der Mark) was tested. PBZ concentrations (0 and 5 ppm) applied by dipping bulbs for 24 hours before transplanting and 5 °C ST (5, 6, 7, 8, 9, 10, 11, and 12 weeks) were evaluated. Mean air temperature throughout the experiment remained between 15 and 15.7 °C. PBZ did not affect the duration of the cycle. ST explained 83% of the variation in the duration of the period transplant-sale time, and the relationship was inverse. PBZ did not affect flower size. There was a significant interaction between treatments for plant height at sale time and at the end of flowering: plant height increased with ST in all cases, but the increase was lower in the PBZ treated plants. Without PBZ and with bulbs stored at 5 °C for 5 to 8 weeks, it was possible to produce commercial plants which were shorter or as tall as plants obtained from bulbs stored at 5 °C for 12 weeks and dipped for 24 hours in a 5 ppm PBZ solution.
