treatments in peat rooting medium at GM-2 and in perlite rooting medium at GM-3, respectively. The longest root length determined in control cuttings (20.91 cm) in perlite rooting medium at GM-2 for x C. leylandii was followed by NAA 1000 ppm treatment (16.80 cm) in the same greenhouse and rooting medium. In addition, the highest number of roots related to this taxon was obtained as 3.95 roots in NAA 5000 ppm treatment in peat rooting medium at GM-3. The results of variance analysis (univariate) of GM, RM, H and the interactions of GM x RM, GM x PH, RM x PH and GM x RM x PH in terms of RP, CP, RL and RN regarding the studied taxa are given in Table 3. When the variance analysis results are examined, there are statistically significant differences (p<0.01) in GM, RM, PH and GM x RM, GM x PH, RM x PH and GM x RM x PH interactions of the studied taxa in terms of rooting and callus percentages. As a result of the variance analysis of root length data obtained for C. lawsoniana ‘Ellwoodii’, statistical differences at 99% confidence level emerged in terms of RM, PH and GM x RM, GM x PH, RM x PH interactions, and at 95% confidence level emerged in terms of GM and GM x RM x PH interaction. There were statistically significant differences (p<0.01) with regard to the number of roots of this taxon in terms of all factors and interactions except H. For C. japonica ‘Elegans’, statistical differences were found in GM and GM x RM interaction (p<0.01) in terms of root length, and only in GM x PH interaction (p<0.05) in terms of root number. While no statistical difference occurred in terms of root number for x C. leylandii, there was a statistical difference in terms of root length only in RM at 99% confidence level. The Duncan test results for the groups formed as a result of the statistical differences obtained in terms of RP, CP, RL and RN regarding the taxa studied and the graphs of the relationship between the greenhouse medium, rooting medium and hormones in terms of rooting percentages are given in Table 4 and Figure 2, respectively. The resulting groups have emerged as a result of the combination of the results obtained in perlite and peat rooting medium depending on the greenhouse medium and hormones. |
