Abstract:
Choosing one year old Erythrophleum fordii seedlings as experimental materials，the effects of the three plant growth regulators with different concentrations（0（CK）、5、15、25、35、45 mg/L） on the root activity，total root length，total root surface area，root diameter，and root volume of Erythrophleum fordii were analyzed.The results showed that compared with CK，GGR-6，GA3 and NAA had distinctly simulative effect on the root growth of Erythrophleum fordii  seedlings.Among them，the simulative effect of GGR-6 was the most obvious，GA3was the second，and NAA was the minimum.Furthermore，as plant growth regulator concentration increased，the growth of root showed first increased and then decreased trend.
