Effects of auxin and urea derivatives on adventitious rooting in chestnut and oak microshoots.

The present study investigated how auxin concentration and the method of application affected the formation of adventitious roots in microshoots of chestnut (Castanea sativa) and oak (Quercus robur). The activity of two urea derivatives (2, 3-MDPU and 3, 4-MDPU) was also evaluated. Microshoots were...

The activity of two urea derivatives (2, 3-MDPU and 3, 4-MDPU) was also evaluated.

The effect of auxin on rooting also differed depending on the application method.
