Title

Other claims from this paper (10)
- Intervention effect The frost treatment increased compensatory root and herbage growth.
- Intervention effect Root regrowth after frost was greater than herbage regrowth in March and April.
- Intervention effect Early-sown plants had higher root and herbage dry matter than late-sown plants in October.
- Intervention effect Early-sown plants had the lowest survival rate when exposed to frost in April.
- Observation Compensatory growth also occurred in the most frost-resistant timothy cultivar in April.
- Observation Concentration of total carbohydrates increased from October to March.
- Observation The greatest carbohydrate increase occurred in the most winter-hardy cultivar of each species.
- Observation Concentration of total carbohydrates decreased in April.
- Association Tolerance to moderate frost was indirectly correlated with total carbohydrate concentration.
- Association Plant survival and ability for compensatory growth were associated with winter-survival adaptation differences among the cultivars tested.
