Effect of cutting storage on rooting of rose cultivars for cut flowers in the four seasons.

The objective of the present study was to evaluate the effect of storage period of cuttings in cold chamber on the rooting of rose during the four seasons, in order to set up a better planting and marketing schedules of cuttings. “Vega” and Versilia Pink cuttings were stored in cold chamber (7° ± 1°C) for variable periods (0, 3, 6 and 9 days) during the four seasons of the year. It was used a completely randomized experimental design, with four replications of three apical cuttings/per plot. After storage the cuttings were kept under intermittent nebulizing and treated with powder indole-butyric acid at a concentration of 2,000 mg/L. The percentage of rooting, the average number of roots and root length were evaluated and recorded on the 30th day after staking. It was concluded that “Vega” cuttings could be stored without damage to those characteristics for variable periods that depended on the season. On the other hand, “Versilia Pink” cutting could be stored during nine days in cold chamber without damage to rooting percentage independent of the season. Cold storage did not interfere on root number but affected average root length for both cultivars.
