Role of Grafting Technique on the Success of Stenting Propagation of Two Rose (<i>Rosa</i> sp.) Varieties

Abstract

The influence of two grafting techniques on the success of stenting (simultaneous cutting and grafting) and some ensuing growth parameters of stentlings were studied under glasshouse conditions. The Avalanch and Peach Avalanch glasshouse rose varieties were utilized as scion and grafted on R. manetti as rootstock. Two grafting techniques namely, splice and omega grafting methods were practiced and graft combinations were inserted in cocopeat-perlit (1:2) medium under mist system. The number of roots, longest root size, shoots and leaf numbers and successful grafting percentage were evaluated after grafting. In Avalanch/R. manetti and Peach Avalanch/R. manetti combinations, higher percentage of successful grafting was observed in the stentlings propagated via omega grafting technique. Furthermore Avalanch/R. manetti stentlings prepared by omega grafting were found to produce more number of roots, shoots and leaves and longest root size as compared to those propagated through splice grafting method. In case of Peach Avalanch/R. manetti combinations propagated via omega grafting more number of shoots was observed as compared to those propagated by splice method. However, these were not significantly different with respect to their leaf numbers. The results showed the superiority of omega grafting procedure.

Response of black mulberry onto white mulberry rootstock to stenting (cutting-grafting) techniques and IBA concentrations

“…However, there is no report on the application of stenting method for mulberries. The results presented here are in opposite with the results of Izadi et al (2013) who reported that omega grafted plants of Avalanch/R. manetti, produced more number of and roots as well as leaves as compared to splice grafted.…”

“…Various techniques such as cleft, side, notch, wedge, and splice are approved for different woody and herbaceous plant species (Hartman et al, 2002;Solgi et al, 2012). The select of grafting and stenting type within plant species could also be related to climatic conditions, scion and rootstock vigor and their size (Izadi et al, 2013). Generally, the activation of rootstock and scion cambium is required for grafting success.…”

“…Callus formation in addition to their joining together with the maximum overlap is one of the most major steps in achievement (Hartman et al, 2002;Solgi et al, 2012). Subsequently, new cambial layers differentiate and making a constant vascular connection between scion and rootstock (Izadi et al, 2013). The activation of cambia and subsequent callus formation and vascular connection depends on several factors such as environmental conditions (for example temperature and humidity), season, plant plant species and plant materials characteristics (Hartman et al, 2002;Izadi et al, 2013;Solgi et al, 2012).…”

“…According to our findings, stented black mulberry onto white one plants by splice method substantially improved all of evaluated traits compared to that omega method (Table 1, Table 2, Figure 3). Some authors reported different stenting methods in horticultural crops (Hartman et al, 2002;Karimi, 2011;Park and Jeong, 2012;Izadi et al, 2013;Babaie et al, 2014;Izadi and Zarei, 2014). However, there is no report on the application of stenting method for mulberries.…”

“…Cutting and grafting is accomplished simultaneously in this technique (Karimi, 2011;Babaie et al, 2014;Pourghorban et al, 2019). It is a valuable technique in propagating of many plant species such as conifers, apple, plum, pear (Hartman et al, 2002), pomegranate (Karimi, 2011), roses (Park and Jeong, 2012;Izadi et al, 2013;Pourghorban et al, 2019), Chinese hibiscus (Izadi and Zarei, 2014), weeping fig (Babaie et al, 2014). However, it is not known about mulberry plants response to different stenting methods.…”
