Effects of IBA, NAA and GA3 on rooting and morphological features of Ginkgo biloba Linn. stem cuttings

Abstract

This study analyzed the potential of production Ginkgo biloba Linn. using stem cuttings. Three different Hormones (IBA, NAA, and GA3) along with control condition were applied to the cuttings, with and without buds, in three doses (1000mg/L, 2000 mg/L and 3000 mg/L) and after one growing season, Eight morphological characteristics of newly generated plants were detected, and a statistical analysis was carried out. All the application developed more number of roots than that of the control group, while all the applications developed longer roots compared to the control group, and the roots of the saplings developed with the 2000 mg/L IBA application were twice longer than those of the control group indicates that the hormone application have a great effect on root development.
