Figure 1

Bell pepper fruit diameter (A), length (B), shape index (C), and pericarp thickness (D) in 2016 as affected by shade levels. The solid lines were fit by either linear or quadratic regressions. The error bars represent mean ± SE

Figure 6

Rates of fruit water loss (A, B) and transpiration (C, D) in bell pepper as affected by shade levels (A, C) in 2016 and storage period (B, D) in 2017. Fruit (20 per treatment) were harvested at the mature green stage. Water loss (weight loss) rate of individual fruit was determined daily gravimetrically during a 7-day keeping period (20 °C, 1.50 kPa vapor pressure difference, and less than 0.2 m·s−1 air velocity). The solid lines were fit by quadratic regression. The error bars represent mean ± SE
