The metabolic pathways and physiological effects of atrazine in Douglas-fir seedlings

Creator:

Peterson, Charles Adrian

Abstract:

Herbicides are being used as a tool by forest managers to speed the restocking of sites where tree seedlings face competition from grasses for limited moisture, light and nutrients. Retarded growth or, more commonly, death of the seedlings would occur if a selective herbicide was not used to control competing...

Some physiological effects of atrazine on Douglas-fir seedlings

Creator:

Peterson, Charles Adrian

Abstract:

This study was undertaken to ascertain some of the physiological effects of the herbicide atrazine on Douglas-fir seedlings. Photosynthetic and respirational rates were measured on seedlings grown in a controlled environment chamber. Height and dry weight increases, shoot/root ratios and percent total nitrogen were obtained from treated and control seedlings...
