Abstract The effects of rooting substrates types and concentrations of auxins and treatment time on the
,
rooting and growth ability of Acacia auriculiformis cuttings were systematically studied and the changes in roo-
ting ability and growth performance of cuttings during rooting were analysed. And the general rooting effect of
different treatments was evaluated based on the analysis of the subordinate function values. The results indica-
ted that the mean number of roots and the length of the longest roots produced by cuttings treated with IBA
were significantly higher than those produced by cuttings trea
