Sentence examples for leaf variable from inspiring English sources

Then the efficiency as a ratio of the surplus production to the investment of leaf variables becomes a question: is the efficiency of investing a unit leaf variable also higher in the open stand?

We define 'leaf productivity' as a surplus production per unit leaf variable (g [leaf variable]−1 d−1), together with their MRT to calculate 'leaf efficiency' (g [leaf variable]−1; Hirose and Oikawa, 2012).

Leaf productivity is the surplus production per unit standing leaf variable per unit time [ eqn (8)].

Differences in MRT among leaf variables were tested by two-way split-plot ANOVA, with stand density and leaf variable as fixed effects.

All measured leaf variables are provided in Table S1 and leaf images are available by request from D.L.R. Two-way analysis of variance (ANOVA) was used to test the influence of growth site and seed source on each leaf size and shape variable.

The standing mean of leaf variable-i (SLi, [i]) is given by (6) SL i = LD i / Δ T where Δ T is the length of the leaf growth period.

The MRT of leaf variable-i (MRTi) is given by (7) MRT i = LD i / f i (T ) The mean leaf productivity (LPi, g [i]−1 d−1) is given by (8) LP i = P s / LD i where Ps is the surplus production (g).

Leaf efficiency (LEi, g [i] −1) is the surplus production divided by the total investment of leaf variable-i, or the leaf productivity multiplied by leaf MRT: (9) LE i = P s / f i (T ) = LP i × MRT i All growth variables were determined individually for focal plants (n = 7 in the open stand and n = 4 in the dense stand) and their mean and s.d. were calculated.

It was higher in the open stand for all leaf variables except leaf number (Table 8).

Leaf efficiencies, defined as carbon export per unit investment of leaf variables, were higher at low density in all leaf variables except for leaf number.

The contribution of leaf variables to surplus production will be quantified.
