In this research, the effects of 85-90% relative humidity and
ındol-3-butyric acid (IBA) doses on softwood top cuttings of
two black mulberry (Types 1 and 2) and one white mulberry
(Type 3) types were studied. Cuttings were taken from early
June (14 Haziran) and applied to the different IBA doses (0,
1000, 2000, 3000 and 4000 ppm). Cuttings were planted in
pumice medium under misting system in the greenhouse for 48
days in order to root. The highest rooting percentage was
determined from Type 1 (black mulberry) in 2000 and 3000 ppm
IBA doses application (100%). The lowest one was control
group from Type 2 (black mulberry) which was not rooted.
Acording to increase liveliness of the cuttings, rooting
percentage increased. Nearly all of the living cuttings were
rooted. The highest ratio of cutting callus formation was
found to be 2000 and 3000 ppm IBA doses (100%) from Type 1;
the lowest one was determined control group of Types 2 and 3
(0.00%). The highest rooting area lenght was found from Type
3 (2.00 cm) and Type 1 (1.92 cm); the lowest one was control
group of Type 2 (0.00 cm). With respect to root numbers, the
highest value was found from
Type 3 (21.73 number/cutting) and Type1 (16.42
number/cutting); the lowest one was control group of Type 2
(0.00 number/cutting). The longest root was determined from
3000 ppm IBA dose of Type 1 (11.23 cm); the highest root
branching value was found from Type 3 in 3000 ppm IBA dose
(16.20 number/cutting) application.
