The incorporation of pig manure vermicompost enhanced shoot and root weight, leaf area and shoot:root ratios of tomato and French marigold (Bachman and Metzger 2008).
However, in water-limited catchments, elevated soil moisture is likely to result in increasing leaf area, while enhanced assimilation allows for the production of more and deeper roots, all of which would act to allow the vegetation to increase the light absorption by the canopy.
Eight meteorological variables and two remote sensing products (i.e., leaf area index, LAI, and enhanced vegetation index, EVI or normalized difference vegetation index, NDVI, or fraction of photosynthetically active radiation, FPAR) are required in our model.
DOI: http://dx.doi.org/10.7554/eLife.02252.080 In order to identify potential interactions existing within the genetic network regulating leaf growth, we pairwised combined 13 gene perturbations each leading to an enhanced leaf size and looked for positive interactions resulting in an increased leaf area larger than the additive combination of the single perturbations.
The WT treatment significantly enhanced pre-anthesis crop growth rate (CGR), biomass and leaf area index (LAI) at anthesis, but the ST treatment showed slight increase as compared with the controls.
We found that tracked vehicles suppressed some species, which are likely to facilitate others by providing shelters above groundwater level (hummock mosses, tussock sedges and shrubs) and enhanced species with effective clonal spread and high specific leaf area.
In the present study, the increase in LAI in response to increase in P level was probably due to enhanced availability of P, which improved leaf expansion and photosynthesis per unit leaf area.
The high degree of canopy temperature depression seen in L. rigidus was not explained by enhanced stomatal conductance or leaf reflectance, but was consistent with a capacity to increase specific leaf area and reduce leaf length: width ratio in the open savanna.
Pruning, by decreasing leaf area, decreased water loss.
