Soil and plant communities co-regulating plant biomass allocation patterns along a saline-alkali gradient, case study of <i>Allium ramosum</i> in Songnen Grassland, Northeast China.

ABSTRACT:

Aims

Plants have developed sophisticated mechanisms to adapt to changing environments. The strategies for biomass allocation is critical for plant to ensure fitness. Increasing soil salinity has a dramatic impact on plant growth and reproduction from the individual to community level. However, our understanding of how plants adapt their biomass allocation strategies to changes in soil salinity and community structure is incomplete.

Methods

We investigated 122 individuals of perennial herb Allium ramosum from 70 plots along a soil gradient in Songnen grassland. Field investigations determined the physicochemical properties of the soil, aboveground biomass, richness and individual and each organ (root, stem, leaf, flower, and bulb) biomass of A. ramosum.
