Terminal stem cuttings of four evergreens [arborvitae (Thuja occidentalis L.), `Calgary Carpet' juniper (Juniperus sabina L.), `Hetzii' juniper (Juniperus virginiana L.), and Tamarix juniper (Juniperus sabina L.)] and four deciduous {Amur maple (Acer ginnala Maxim.), common lilac (Syringa vulgaris L.), ninebark [Physocarpus opulifolius (L.) Maxim.], and viburnum (Viburnum farreri Stearn)} woody landscape shrubs were treated with 0%, 0.1%, 0.3%, or 0.8% IBA mixed in talc or with 0%, 0.25%, 0.5%, 1.0%, or 1.5% IBA dissolved in 95% ethanol, radiator antifreeze (95% ethylene glycol), or windshield washer fluid (47.5% methanol). None of the carriers were phytotoxic to the cuttings. Cuttings treated with IBA in radiator antifreeze or windshield washer fluid produced rooting in most taxa similar to those treated with IBA in ethanol. Cuttings of the evergreen taxa produced more roots with liquid than with talc IBA at similar concentration ranges. There were some differences in rooting performance (expressed in terms of percent rooting, mean root count per rooted cutting, and length of the longest root per cutting) of taxa to solvents and IBA concentrations. However, such differences, if any, were generally small or commercially insignificant, except for ninebark, which rooted optimally with no IBA and exhibited a large reduction in percent rooting with increasing IBA concentrations in windshield washer fluid. Chemical name used: indolebutyric acid (IBA).
