The effects of various applications on adventitious root formation and rooting in some fruit species

In the treatment; Cresthaven peach, Iğdır apricot, Margaret pear and Black Bursa fig varieties grafted on seedling rootstock were used. In thesis study; the following applications were made 0.5 cm above the node in one year old 15 shoots which were taken from a tree (each tree is one replication); A) parallel scrapes 2 for each side on the bark to the wood, B) 5 mm. bark compression and 2 parallel scrapes, C) 2 notches to the xylem, D) darkening by wrapping with 1 cm black band on cutting base, E) shaking on the shaker 5 hours long. When the results of the treatment were examined, phenologically; it was seen that the least bud swell and bud burst was in Cresthaven and Iğdır varieties; while the most bud swell and bud burst were respectively in B, E, C, A and D applications in Margaret variety and respectively in E, C, D, B and A applications in Black Bursa variety. Considering the viability rate of cuttings, it was identified that in each different applications on Cresthaven, Iğdır, Margaret and Black Bursa varieties, the viability rate of the cuttings was different due to different applications. When the number of cutting with callus was observed among the cuttings whose rooting happened in 3 different lifting period from rooting unit, the cutting was seen which developed callus with different rate, changing according to applications due to lifting periods. When the number and rate of the rooted cutting was observed, the rooted cutting was seen in C, D and E applications in Cresthaven variety while the rooted cutting was not seen in any application of Iğdır variety due to the liftings. In Margaret variety, the most rooted cutting was respectively on the applications of D as the first, E as the second and A, B and C as the third. In Black Bursa variety, it was identified that all of the cuttings lifted from A, B, C, D and E applications were rooted at the same level.
