The present thesis showed that root elongation of alfalfa (Medicago sativa L.) during a 24-h period was inhibited by 80% by the exposure to 5 umol L-1 Al and its roots was obviously stained by eriochrome cyanine R; however, the roots of stylo need to be exposure to 30umol L-1 Al in order to get obviously stained with its root elongation was inhibited by 68%, which shows, for stylo, its ability of tolerance to aluminum is strong.

本研究发现，5 μmol L~(-1)AlCl_3使紫花苜蓿根长抑制80.0％，铝处理后的根尖被铬天青明显染色，而柱花草经30 μmol L~(-1)的AlCl_3处理后方观察到根尖明显染色的现象，根的伸长受抑制68.0％，表明柱花草抵御铝毒能力较强。
