Other claims from this paper (9)
- Intervention effect At physiological maturation, mean plant height fell by 12.62 and 14.29% under the two stress levels relative to full irrigation.
- Intervention effect At physiological maturation, mean stem diameter fell by 11.94 and 9.41% under the two stress levels relative to full irrigation.
- Observation Euroflor was superior to Flame in plant height at most growth stages in the spring season of 2000.
- Observation Flame was superior in plant height at most growth stages in spring 2001 and in stem diameter after 30 days from planting.
- Intervention effect Presowing seed soaking in paclobutrazol and pix solutions decreased plant height at most growth stages in both seasons and as a mean of seasons.
- Intervention effect At physiological maturation, soaking in paclobutrazol and pix decreased mean plant height by 4.49 and 2.78% relative to unsoaked seeds.
- Intervention effect At physiological maturation, soaking in paclobutrazol and pix decreased mean plant height by 5.27 and 3.57% relative to soaking in water.
- Intervention effect Soaking seeds in paclobutrazol and pix solutions increased stem diameter at physiological maturation by 9.78 and 12.18% relative to unsoaked seeds as a mean of seasons.
- Recommendation The authors conclude that presowing seed soaking in water or a growth regulator can reduce plant height and increase stem diameter to support drought tolerance.
