- Intervention effect Shade at all four growth stages decreased cotton leaf photosynthetic rate by 43 to 55%.
- Intervention effect Shade increased total chlorophyll concentration of cotton leaves by 14% on a leaf area basis.
- Intervention effect Shade did not affect leaf dark respiration rate of cotton.
- Intervention effect Starch concentration in cotton leaves and floral bracts decreased sharply under shade.
- Intervention effect Hexose concentration in shaded cotton showed only minor changes.
- Intervention effect Shade at the first flower and peak flower stages did not decrease total nonstructural carbohydrate (TNC) concentration in 20-d-old cotton floral buds.
- Intervention effect Shade at the boll development stage decreased total nonstructural carbohydrate (TNC) concentration in 20-d-old cotton floral buds.
- Intervention effect Averaged over four growth stages and two years, shade decreased TNC concentration in cotton leaves by 47 to 71% relative to unshaded controls.
- Intervention effect Averaged over four growth stages and two years, shade decreased TNC concentration in cotton floral bracts by 37 to 48% relative to unshaded controls.
- Intervention effect Averaged over four growth stages and two years, shade decreased TNC concentration in 20-d-old cotton floral buds by 5 to 20% relative to unshaded controls.
- Intervention effect Shade at the peak flower stage (1994) or boll development stage (1993) caused the greatest decrease in leaf TNC concentration.
- Intervention effect Shade at the boll development stage caused the greatest decrease in TNC concentrations of cotton bracts and floral buds.
