The Importance of Rootstocks and Rooting Media on Vegetative Propagation of Roses in Stenting Method

Due to benefits of grafting in commercial rose propagation simultaneous cutting and grafting method is one of the most important research topics for roses. Therefore, in the present investigation two types of rooting media and three propagation methods were compared. Rotting media were both sand and peat in equal parts or perlite and peat in equal parts. The propagation methods included grafting (stenting) Rosa hybrida ꞌBaccaraꞌ on two rootstocks R. canina / R. canina ꞌInermisꞌ or propagate it by cuttings. The results showed that mixture of sand and peat in equal proportions was the best medium which resulted in the maximum rooting percent. Mean comparisons showed that R. canina rootstock showed the highest rooting percent and quality (length (cm), number of roots), callus formation and rooting compared to R. canina ꞌInermisꞌ. An increase in callus formation resulted in the increase in the number of roots, rate of rooting and percent of rooting.
