Abstract

This
study was conducted to investigate the effects of rooting medium pH and IBA
treatments in rooting of tea cuttings. In the study, 10 tea genotypes with
‘Tuğlalı’ are used as materials and perlite is used as the rooting medium. In
the experiment, the effects of three different pH levels (7.0, 5.5, and 3.5)
and 3 different applications of IBA (0, 4000, and 6000 ppm) on rooting tea cuttings
and growth of tea sprouts were investigated. According to the findings of the
study, the best results in the tea plants are taken from 6000 ppm IBA and 5.5
pH applications. In 6000 ppm IBA, rooting rate is 65.26 %, the most advanced
root length is 4.90 cm, the root number is 4.97 units and the root quality is
defined as 1.33. In cases where the rate of rooting medium pH is 5.5, rooting
rate is 69.69 %, the most advanced root length is 9.41 cm, root number is 8.70
units and root quality is seen as 1.70.  As
the growth rate of tea cuttings, 3.5 pH (79.28 %); in terms of the ratio of
growth length, 6000 ppm IBA (7.96 cm) and 3.5 pH (9.20 cm) have given the best
results. When all the results are evaluated together, 6000 ppm IBA treatment at
5.5 pH level is recommended for rooting and quality sapling production.
