Other claims from this paper (15)
- Intervention effect At 20°C, 75% shade reduced apple shoot growth and leaf number.
- Intervention effect At 25°, shading had no effect on apple shoot growth and leaf number.
- Intervention effect At high soil water potential, 75% shade significantly reduced total leaf area.
- Intervention effect At low soil water potential, shading had little effect on total leaf area.
- Intervention effect Under full sun, declining soil water potential reduced total leaf dry weight by 46%.
- Intervention effect Under shade, declining soil water potential reduced leaf dry weight by 20%.
- Intervention effect Under full sun, rising temperature decreased total stem dry weight.
- Intervention effect Under shade, temperature had little effect on stem dry weight.
- Intervention effect At 75% shade, rising temperature decreased specific leaf weight.
- Intervention effect In full sun, temperature had no effect on specific leaf weight.
- Observation Environmental interactions did not influence specific leaf weight of new leaves.
- Intervention effect Lower soil water potential increased the proportion of alkanes in leaf wax.
- Intervention effect Lower soil water potential increased the proportion of wax esters in leaf wax.
- Intervention effect Alkane content rose as temperature rose.
- Method / resource Environmental conditions changed photosynthetic functioning and masked prometryn effects, making the herbicide unreliable for measuring foliar absorption.
