Rooting Performances of Promising Black Mulberry (Morus nigra L.) Genotypes Determined in Tokat Province under Same Environmental Conditions

Abstract

In this study, it was aimed to examine the rooting performance of hardwood cuttings taken from the promising black mulberry genotypes Kemalpaşa, Yelpe, Merkez 3, Merkez 6, Kocacık, Çamdere, and Merkez 7 determined in the province of Tokat under the same environmental conditions. All cuttings were immersed in 6000 ppm IBA solution for 5 seconds before planting and planted on heated bottom tables. The cuttings, which were kept in rooting units for about 3 months, were then removed and measurements were made on them. As a result of the study, statistically, differences were found in root length, root diameter, root number, callus formation rate and rooting rates in the parameters examined. There was no statistically significant difference between genotypes in decay rates. Decay rates of genotypes are between 12.96% - 41.67%, callus formation rates are between 70.83% - 95.39%, rooting rates are between 60.41% - 92.64%, root lengths are between 5.85 - 7.52 cm, root diameters are between 1.42 - 1.75 mm, and root numbers are between 7.87 - 12.67 root/cutting has taken values. In the light of the information obtained as a result of the study, it was determined that Yelpe, Çamdere, and Merkez 6 genotypes showed high rooting success. These results are important in terms of shedding light on the research to be done in order to determine the various studies and the performance of the saplings. It is also a determining factor for enterprises producing saplings.
