Table I.
Statistical comparison of the Se accumulation and volatilization curves shown in Figure 2 for Indian mustard supplied with selenate or selenite
| Se Volatilization and Accumulation | Selenate Slope | Selenite Slope | Selenate versus Selenite |
|---|---|---|---|
| Se volatilization (μg Se plant d−1) | 0.469 (0.0003) | 0.859 (0.0007) | 0.0029 |
| Root Se accumulation (μg Se root d−1) | 25.9 (0.0039) | 52.85 (0.0005) | NSa(0.629) |
| Shoot Se accumulation (μg Se shoot d−1) | 105.3 (<0.0001) | 11.2 (0.0028) | 0.0075 |
| Total plant Se accumulation (μg Se plant d−1) | 131.2 (0.0002) | 64.04 (0.0006) | 0.0035 |
The slopes of the curves are shown with their accompanying P values in parentheses. Significant differences between the slopes of the curves for selenate and selenite are presented in column 4.
