The effects of growth medium acidity, exogenous growth regulators, and nitrogen fertilizer on the acceleration of Fraser fir seedling growth
… applied at the higher concentration (100 ppm). GA3 had no main effect on either shoot or root growth. However. GA3 did increase shoot growth slightly in the absence of BAP. IBA increased root growth up to 26%. IBA had no significant effect on shoot growth. Nitrogen fertilizer was supplied weekly …
