Effect of Size of Shoot Cuttings on the Growth of <I>Populus</I> × <I>Euramericana</I> '72/58'

Abstract

Nine size. of shoot cuttings (viz. 10×0.5, 10×1.0, l0×1.5, 20×0.5, 20×1.0, 20×15, 30×0.5, 30×10, 30×l.5 cm) of Populus × euramuicana '72/58' were tried in a randomized block design with eight replications in the research nursery of the Forest Research Institute, Dehra Dun, to find out tbe optimum size cutting. for vegetative propagation of poplars under Debra Dun conditions Based on the overall performance and development of the plants in respect of sprouting, height and diameter growth and survival per cent etc., it is concluded that for raising plants in one growing season, the length of cuttings should not be less than 20 cm and the thickness should preferably be around 1.5 cm.
