The effect of excised-leaf water loss (ELWL) values, independent: after 0–3 h, after 4–6 h, and after 0–6 h (independent variable, x), on the mass of stems plant−1, the number of grains, the mass of grains plant−1 (dependent variable, y) estimated by regression model y = a x + b.
| Independent Variable | Dependent Variable | Model | Percentage Variance Accounted | Standard Error of Observations |
|---|---|---|---|---|
| ELWL after 0–3 h | The mass of stems plant−1 | y = 21.53 *** − 0.314 * x | 3.0 | 4.87 |
| The number of grains | y = 20.184 *** − 0.028 * x | 3.2 | 4.86 | |
| The mass of grains plant−1 | y = 20.109 *** − 0.637 * x | 2.6 | 4.88 | |
| ELWL after 4–6 h | The mass of stems plant−1 | y = 15.14 *** − 0.285 x | 2.0 | 5.23 |
| The number of grains | y = 13.051 *** − 0.0057 x | - | 5.3 | |
| The mass of grains plant−1 | y = 12.935 *** − 0.074 x | - | 5.3 | |
| ELWL after 0–6 h | The mass of stems plant−1 | y = 33.23 *** − 0.500 * x | 3.0 | 7.77 |
| The number of grains | y = 30.39 *** − 0.0286 x | 0.8 | 7.86 | |
| The mass of grains plant−1 | y = 30.23 *** − 0.611 x | 0.4 | 7.88 |
