Other claims from this paper (7)
- Observation Tall fescue cultivars differed consistently and significantly in carbon isotope discrimination at the wettest water level (WL-2) at Harvests 2 and 4 in successive years.
- Observation Tall fescue cultivars differed significantly in carbon isotope discrimination across four water levels at Harvest 4.
- Observation Relative differences among tall fescue cultivars were consistent across water levels and between harvest dates.
- Association Mean carbon isotope discrimination in tall fescue decreased in a near linear manner from the wettest (WL-2) to the driest (WL-5) water level.
- Observation The mean trend of discrimination across water levels was partitioned as 95% linear and 5% quadratic.
- Association Correlations between carbon isotope discrimination and dry matter yield were nonsignificant at the higher water levels (WL-2 and 3).
- Association Correlations between carbon isotope discrimination and dry matter yield were positive at the lower water levels (WL-4 and 5).
