fluctuations in temperature. However, there
are reports with contradictory results in Sedum acre and
Arabidopsis thaliana, which showed similar or even bigger plant
growth in shallower substrates It was attributed to the reason that deep substrate is of
relatively little benefits to the species with shallow root system.
Similarly, the data obtained from the present study indicate that
shallower substrate is advantageous to biomass accumulation and
growth of S. lineare.
