Abstract

An experiment was conducted to investigate the effects of time and severity of pruning on growth and branch development of rose, at the Ferdowsi University, Mashhad, Iran in 2012. The experiment was designed based on Randomized Complete Block Design (RCBD). This study was replicated four times (January, February, march, April) and 2 type of pruning (heavy and light) and the rose cultivar used was miniator. Results of pruning-experiments showed significant differences in the parameters. Among the type of pruning, heavy pruning was produced maximum results for all the mentioned parameters. Among the time of pruning, maximum number of flowers (188.75) and plant height (63.9 cm) were recorded in January month. Minimum flowers (136.25), with smallest size (1.95 cm in diameter) were observed in April month. On the basis of the results obtained it is concluded that winter pruning had a substantial effect on certain important parameters i.e., flower diameter and flower number.
