Effects of Some Chemical and Mechanical Applications on Branching in Production of Apple Nursery Trees

In this study, the effects of some chemical [6-Benzyladenine (6-BA), Promalin (6-BA+GA4+7)] and echanical applications on the Jersey Mac, Summer Red, Galaxy Gala, Granny Smith, Fuji and Braeburn grafted on the M9 apple rootstock have been studied under echological conditions of Isparta-Eğirdir in 2009. On the interpretations on nursery tree carried out in this work, the longest fidanlar have been found from Braeburn types on the application of 450 ppm Promalin to be 142.37 cm. When plants producing side arms are studied, the plants mostly producing side arms have been obtained from Braeburn types with 550 ppm 6-BA (7.30 item/nursery tree and Braeburn types again with 550 ppm 6-BA (7.30 item/ nursery tree. On the study of the angle of arm, the arms with the largest angle have been obtained on the Summer Red type (60.110) in the control group, on the application of branch stripping, on the Summer Red (59.080) type and Granny Smith type (57.790) 550 ppm with Promalin application. The interpretations made according to TSE standards of bodur fruits, the nursery tree (% 100) left control applications, the nursery tree (% 99) subjected to 450-55 ppm Prolmalin, the nursery tree subjected to stripping application (% 98) and cutting the tip of seedling 3 application have been classifies as the first class nursery tree. In the study, the most quality nursery tree have been obtained from Jersey Mac (% 99), Braeburn (% 98), Galaxy Gala (% 97) and Granny Smith (% 96).
