Other claims from this paper (19)
- Intervention effect The reported exposure increased disease incidence significantly.
- Intervention effect Mycorrhizal infection prevented the increase in disease incidence.
- Observation Pathogen presence was required for changes in soluble and wall-bound secondary compounds of roots and needles.
- Intervention effect Ozone alone did not induce those secondary-compound changes.
- Intervention effect Mycorrhizal infection appeared to dampen secondary-compound induction.
- Observation H. annosum significantly accumulated both pine stilbenes locally and systemically in more susceptible seedlings.
- Intervention effect Ozone significantly increased both stilbenes in roots of susceptible seedlings.
- Intervention effect Ozone reduced needle pinosylvin.
- Intervention effect Ozone had no effect on needle pinosylvin 3-methyl ether.
- Observation Root catechin content decreased in infected seedlings, more so with ozone.
- Observation An unidentified compound accumulated gradually in infected roots.
- Association The authors associated the unidentified compound with resistance.
- Intervention effect Ozone had little effect on accumulation of the unidentified compound.
- Observation Pathogen presence was required to induce the lignin-like response.
- Intervention effect Ozone inhibited the pathogen-induced lignin-like response.
- Intervention effect Applied pinosylvin was phytotoxic, causing needle discoloration and wilting.
- Intervention effect Applied pinosylvin lowered chlorophyll content in excised seedlings.
- Intervention effect Applied pinosylvin increased transpiration in excised seedlings.
- Observation Needle pinosylvin accumulated to levels comparable to the main experiment.
