- Intervention effect SWE plus iron increased photochemical activity by 14% to 15%.
- Intervention effect SWE plus HA increased SOD activity within the reported 49% to 114% range.
- Intervention effect SWE plus HA plus iron increased SOD activity within the reported 49% to 114% range.
- Intervention effect Natural growth regulators with or without iron increased May photochemical activity 13% to 46% against control.
- Intervention effect Adding iron to each growth regulator treatment improved fall and winter leaf color.
- Intervention effect All growth regulator and iron treatments except HA alone in 1998 increased root mass 17% to 29%.
- Intervention effect Under sustained low soil moisture, natural growth regulators with or without iron increased photochemical activity and SOD activity.
- Recommendation The authors recommend natural growth regulator applications before and during summer abiotic stress.
