and peat were used as rooting media in all greenhouse media. IBA (Indole-3-Butyric Acid) and NAA (α-Naphthalene Acetic Acid) of 1000 and 5000 ppm dosages were selected from among the auxin group hormones to induce rooting from plant growth regulators for rooting. All hormone implementations were made in each greenhouse and rooting media.
Since no temperature regulation was made in Greenhouse-3 media, the temperature measurements were taken three times a day (morning, noon and evening) with a thermometer until completion of the study. Monthly temperature values in Greenhouse-3 media are given in Figure 1.
The study was set up to be three replications, according to the “randomised complete block design”. A total of 900 cuttings were planted to rooting including 1 species x 2 hormones x 2 doses x 3 greenhouse media x 2 rooting media x 10 cuttings x 3 replications (720 cuttings) and control cuttings in each media (180 cuttings). Cuttings were taken from determined stock plant early in the morning. The cuttings were generally prepared to be 10-12 cm long. The bottoms of the prepared cuttings were immersed in powdered hormone and transferred to the rooting media. The irrigation was made after the cuttings were transferred to rooting media. Thus, it was ensured that the cuttings were fully seated in the rooting media. In the measurements made in the cuttings, the first callus and first root formation dates, rooting percentage (RP), callus percentage (CP), root length (RL) and the number of root (RN) values were determined (Figure 2). Rooting percentage was expressed as a percentage of the total cutting by determining the number of cuttings forming root. Callus percentage was determined to be the percentage of total cutting by determining the number of non-rooted cuttings with callus formation. Root length was to the length of roots formed in cuttings. And root number was the number of roots occurred in cuttings.
Statistical analysis: The data were analyzed using SPSS 23 statistical program. Analysis of variance (univariate) was conducted to determine the effects of different greenhouse media, rooting media and hormones on rooting percentage, callus percentage, root length and the number of root. In addition, Duncan test was performed to determine the groups that were found in terms of hormones and greenhouse media for RP, CP, RL and RN.
The values of RP, CP, RL and RN in terms of measured values of greenhouse media, rooting media and hormones used in the study are given in Table 1.
As a result of the study, it was determined that perlite rooting media was more effective in rooting compared to peat rooting media, and peat rooting media was more effective in callus formation by comparison with perlite rooting media in all greenhouse media. Compared to peat rooting media, of the average difference was 82.43% in terms of rooting success in perlite rooting media in Greenhouse-1 media. This difference was 94,12% in Greenhouse-2 media and 85,90% in Greenhouse-3 media. The highest rooting percentages occurred in all greenhouse media were in the perlite rooting media. Accordingly, the highest rooting percentages occurred in NAA 1000 ppm treatment with 76.67% in
