Growth Performance of Twelve New Clones of Poplar in Punjab, India

摘要

Height, diameter growth and volume production of 12 clones of poplar were evaluated at Kharkan Research Station, Hoshiarpur (Punjab) at the age of 3 years. The clone WSL - 39 achieved the best growth and maximum volume, attaining diameter of 14.74 cm;height 14.42 m and volume 0.1040 m~3/tree. This clone out performed the clones for growth and volume since the beginning. The volume production of clone Udai was at par with WSL - 39 at 2 and 3 years of age. On the basis of present results, WSL-39 and Udai clones can be included for plantation to broaden the genetic base and more importantly for productivity enhancement.
