Abstract: The cutting propagation technology of the top of Adhatoda vasica Nees and semi-lignified branches was studied with a L₉（3⁴） orthogonal test which consisted of substrate, hormone type and hormone concentration. The results showed that cortex rooting of the top cuttings was facilitated by hormone. The rooting rate and average root number of the top cuttings with different hormone treatments was significant difference. The highest rooting rate was 66.67% with 100 mg/L IBA in roseite. The rooting of the top cuttings was easier than the semi-lignified cuttings.

Key words: Adhatoda vasica Nees, cutting rooting, rooting rate
