Walnuts taken from various areas of Van Lake basin were used as research material. In order to determine the effects of the application of root cutting methods on walnut seedlings after germination three different applications were used (cutting of radicle from 5 cm, cutting of radicle from 7 cm and control). One third of the walnuts which were ripped from the rooting area after germination have been planted without cutting the radicle and planted back to the germination area. The research revealed that the seedlings from control group performed well in shoot growth while the seedlings from 7 cm radicle cut group gave better results in the parameters about root development. The research also indicated that the area that welnut seeds were taken affected the seedling performences.
