Increasing Rooting Efficiency of Hardwood Cutting in Rose

The efficiency of rooting of hardwood cutting was investigated in Rosa multiflora, mainly used as a rootstock. Rosa multiflora thornless cultivar ‘Hort No. 1’ was cut 20cm and stored in 4 cool conditioned chamber for a week in September 20th 2013. The effect of rooting media was investigated by using various media (Vermiculite 100%; Perlite 100%; Vermiculite 50% : Perlite 50%) and was prepated in 24 tray pot for hardwood cutting. Seasonal rooting efficiency was studied for six month periods from Sempember 2013 till March 2014 in the mixed-media (Vermiculite 50% : Perlite 50%) for the hardwood cutting of Rosa multiflora. All the measures were conducted after two months of cutting. The mixed-media showed best rooting efficiency, and hardwood cutting in November was most efficient. Thereafter, we propose to perform hardwood cutting in Rosa multiflora in November in the mixed-media.
