Effects of light, banding, and IBA treatments on rooting of Lindera Benzoin stem cuttings
An experiment was conducted to assess whether various light and banding treatments could increase rooting in stem cuttings of Lindera benzoin L., a difficult-to- root woody plant. Stock plants were grown under one of three light conditions (light, shade, or etiolation) and emerging shoots received either a banding treatment with VELCRO and varying concentrations of IBA in the form of Hormodin (mfr. OHP, Inc.; Morrisville, NC) or received no band. Data on rooting percentage and number of roots per cutting were analyzed using logistic and Quasi-Poisson regression, respectively. Etiolated cuttings treated with VELCRO without IBA had the highest rooting probability and number of roots; however, etiolated cuttings across all banding treatments had similarly successful results. Additionally, there were a number of significant differences in rooting probabilities and root numbers between banding treatments within the shade and light-grown groups.
