Other claims from this paper (14)
- Intervention effect Growth of all three cultivars declined under saline water at pH 6.4.
- Intervention effect French Vanilla height, leaf dry weight and shoot dry weight fell 20% to 25% under 4 dS·m −1 irrigation.
- Intervention effect Flowering shoot number and flower diameter and number were not significantly affected until salinity exceeded 8 dS·m −1.
- Association Growth of Flagstaff and Yellow Climax declined as water conductivity rose.
- Intervention effect Flagstaff shoot dry weight fell 30% under 4 dS·m −1 irrigation.
- Intervention effect Yellow Climax shoot dry weight fell 24% under 4 dS·m −1 irrigation.
- Intervention effect Additional salt stress did not further reduce dry weight production in tall cultivars.
- Intervention effect At pH 7.8, French Vanilla shoot dry weight was 50% lower than at pH 6.4.
- Intervention effect At pH 7.8, Flagstaff shoot dry weight was 89% lower than at pH 6.4.
- Intervention effect At pH 7.8, Yellow Climax shoot dry weight was 84% lower than at pH 6.4.
- Association Compactness did not increase following dry weight reduction.
- Observation Marigolds were rated moderately tolerant to salinity.
- Observation An 8 dS·m −1 irrigation threshold corresponded to 3.64 dS·m −1 saturated extract conductivity.
- Recommendation Marigolds show promise for salt-affected landscapes if soil solution remains acidic.
