Other claims from this paper (19)
- Observation Diseased wild rice seeds were shrunken, light weight and discolored, sometimes pink from fungal growth.
- Observation F. graminearum predominated in whole and shattered seed.
- Observation F. anthophilum was frequently isolated at most growth stages.
- Observation F. subglutinans was frequently isolated at most growth stages.
- Observation F. acuminatum was infrequently isolated at one or more growth stages.
- Observation F. culmorum was infrequently isolated at one or more growth stages and only from whole seed in the seed-structure comparison.
- Observation F. solani was infrequently isolated at one or more growth stages.
- Observation F. semitectum was infrequently isolated at one or more growth stages.
- Observation F. camptoceras occurred only in shattered seed.
- Observation F. graminearum was rarely isolated from processed seed and was the only species found there.
- Observation Fusarium isolation was highest in shattered seed and peaked during milk and dough stages in cultivated seed and milk stage in natural seed before declining to ripeness.
- Observation Fusarium was isolated most frequently from whole seed rather than palea and lemma or caryopsis in three cultivated fields.
- Observation F. graminearum and F. anthophilum were frequent across seed structures; F. sporotrichioides occurred only in whole seed, F. moniliforme in all listed structures, and F. subglutinans in whole seed and palea and lemma.
- Observation Deoxynivalenol and nivalenol were detected in three F. graminearum isolates.
- Observation Neither mycotoxin was detected in the source wild rice seed samples.
- Association Fusarium survival was similar in cultivated and natural seed sources.
- Intervention effect Fusarium survived in whole seed without water immersion but not in immersed seed.
- Intervention effect Fusarium survival was better at 4°C than -20°C.
- Intervention effect F. graminearum was reisolated from 81% of inoculated-plant seed and absent from noninoculated-plant seed.
