The inhibition of coleoptile elongation is alleviated when exogenous auxin was added to the medium under the low concentrations of Cu2+ stress. However, under high concentrations of Cu2+ stress, as the toxicity is so much, exogenous auxin is not available any further.

小麦胚芽鞘的生长只表现为细胞的伸长，原理为生长素作用的结果，外加生长素，发现生长素缓解了重金属铜对胚芽鞘伸长作用的抑制，而在高浓度时，由于毒害太大，所以无效。
