Claim · model-written summary
At Boort and Walpeup a similar negative trend was weakened by outliers in two cultivars at each site.
Verbatim
e0“At Boort and Walpeup there was a similar negative trend, but values for 2 cultivars at each site were outliers, which weakened the trend”
e1“Post-anthesis decrease in stem weight was inversely related to grain yield only at Horsham”
e2“wheat cultivars”

Other claims from this paper (14)
- Observation All wheat dry matter components ranked Horsham above Boort above Walpeup.
- Observation Dry matter differences between Boort and Walpeup were not always significant.
- Observation Total dry matter at anthesis was similar at Walpeup and Boort and less than Horsham.
- Observation Wheat grain yield increased from Walpeup to Boort to Horsham.
- Association Across sites, leaf dry matter related to grain yield.
- Association Across sites, stem dry matter related to grain yield except in cv. Argentine IX.
- Association Across sites, total dry matter related to grain yield.
- Association Within sites, ear dry matter at anthesis related to grain yield.
- Observation At Horsham and Walpeup, wheat grain yield exceeded dry matter increase from anthesis to maturity for all cultivars.
- Observation At Boort, wheat grain yield exceeded postanthesis dry matter increase in five cultivars.
- Mechanism The yield versus dry matter comparison indicates stem reserves contributed to grain filling.
- Association Stem weight decline after anthesis inversely related to grain yield only at Horsham.
- Mechanism The authors suggest differential stem reserve remobilisation may explain cultivar adaptability.
- Association Yield stability was not related to stem weight loss during grain filling.
