Title

Yong-In Guk Korean Journal of Weed Science 2003
Other claims from this paper (14)
- Intervention effect Low ALA concentrations increased barley shoot fresh weight by 12-26%.
- Intervention effect Low ALA concentrations increased wheat shoot fresh weight by 3-9%.
- Intervention effect High ALA concentrations inhibited wheat shoot fresh weight by 34-83%.
- Observation ALA synthesis capacity was higher in barley than wheat across days 5 to 25.
- Intervention effect After dark ALA treatment and light exposure, barley and wheat showed rapid electrolyte leakage.
- Intervention effect That treatment reduced chlorophyll content in barley and wheat.
- Intervention effect That treatment increased lipid peroxidation in barley and wheat.
- Observation ALA herbicidal action was similar in barley and wheat.
- Intervention effect At 5 mM ALA, Proto Ⅸ had the greatest accumulation ratio among measured porphyrins.
- Intervention effect Barley Proto Ⅸ reached over 23-fold control after 12 dark hours.
- Intervention effect Wheat Proto Ⅸ reached over 26-fold control after 12 dark hours.
- Observation Proto Ⅸ accumulation was greater after 12 dark hours than after 4 light hours.
- Observation Other porphyrins changed little in either light or dark treatment.
- Mechanism Authors attribute ALA phytotoxicity to accumulated Proto Ⅸ photodynamic action.
