Total growth and radiation interception of kales grown under the control and UV-B exposure conditions for 2 days before harvest.
| Treatment | Total Growth Parameter | Total Radiation Interception Per Plant | |||
|---|---|---|---|---|---|
| Fresh Weight (g) | Dry Weight (g) | Leaf Area (cm2) | PAR 2 (mmol Plant−1 d−1) | UVBE 3 (MJ Plant−1 d−1) | |
| Control | 79.5 ± 14.0 1 | 7.39 ± 1.83 | 1142.5 ± 184.8 | 914.33 ± 209.50 | - |
| +UV-B | 67.8 ± 6.3 | 6.91 ± 0.94 | 1006.0 ± 67.6 | 739.48 ± 102.24 | 2.91 ± 0.47 |
1 Data represent mean ± SD (n = 3). The mean difference between treatments was not significant. 2 PAR, photosynthetically active radiation in the range of 400–700 nm. 3 UVBE, biological effective UV radiation in the range of 280–400 nm.
