The evaluation of grafting success rate in some rose cultivars by the application of treatments with Ceraltin

Abstract

The rose is a very popular plant species, it has an outstanding ornamental value and it has been grown since ancient times (Palocsay and Wagner, 1966). Tree roses are represented by the cultivars that are trained with trunk and stem or they are obtained by grafting some erect or even climbing cultivars, in the latter case weeping roses would result (Mateescu, 2002). The research was carried out in the experimental field of the Floriculture Laboratory in the framework of the Fruit Research Station Cluj. The aim of the research was to contribute to the increase of the success rate in the process of obtaining tree roses, by the use of Ceraltin® for increasing the grafting compatibility and better subsequent plant growth. The research was carried out in the years 2009-2011, as a series of bi-factorial experiments, in which the two factors, the cultivar and treatment with Ceraltin®, each had four, respectively two graduations. The experimental results were processed by the analysis of variance, by the “Duncan” test (Ardelean et al., 2002). Based on the experimental data, we conclude that the highest grafting success rate, in all the rose cultivars we studied, was obtained as a result of using the Ceraltin® for increasing grafting compatibility. The statistical rate of the effect of the treatment with the Ceraltin® is very high (82%) as compared to the effect of soil (16%), whereas the effect of interaction of the two factors is only 2 % of the total effects.
