A Comparison of Field and Growth Chamber Productivity of Three Poplar Clones

Three clones of Populus were grown at two field locations (Ames, Iowa, and Rhinelander, Wisconsin) and in the growth chamber under photoperiods of 13, 14, and 15 hours. Clones were ranked by size for seven growth variables, and correlations between field and growth chamber growth were calculated. Growth chamber and field rankings were similar for most variables and both locations, and correlation between field and growth chamber performance increased with increasing growth chamber photoperiod. Results indicate that growth chambers can be used for initial rapid selection of poplar clones for field trials.
