Distinguishing the biomass allocation variance resulting from ontogenetic drift or acclimation to soil texture.

In resource-poor environments, adjustment in plant biomass allocation implies a complex interplay between environmental signals and plant development rather than a delay in plant development alone. To understand how environmental factors influence biomass allocation or the developing phenotype, it i...
