Effect of Light and Cutting Age on Rooting in Quercus Bicolor, Quercus Robus, and Quercus Macrocarpa Cuttings

Amissah, J. N. and Bassuk, N. International Plant Propagators' Society, combined proceedings 2007, 57:288-292. 2008.

This study investigated the effect of light and etiolation with or without stem banding on rooting in Quercus robur, Q. macrocarpa, and Q. bicolor cuttings. Percent rooting in Q. bicolor and Q. robur cuttings, taken from greenhouse-grown stock plants averaged 84.9% and 63.8%, respectively. In a second experiment using field-grown stock plants, cuttings were taken at 3-week intervals, from four light and stem banding treatment groups. In Q. bicolor cuttings, rooting response was significantly increased by stock plant etiolation (p < 0.01) and early cutting age (p < 0.0001), but not stem banding (p > 0.05). Rooting decreased (p < 0.0001) as cuttings aged across treatments with an overall rooting percentage of 62.3% at 3 weeks, decreasing to 10.3% at 6 weeks and 4.7% by the 9th week. In a later field experiment, rooting response in Q. macrocarpa cuttings was improved by taking cuttings at 2 weeks after etiolation treatment.
