Seasonal dynamics of total soil seed banks in gaps and under canopies in the study on the role of seed banks in the regeneration potential of Chinese temperate secondary forests.

<p>Different lower case letters indicate significant seasonal differences in seed density in both the gaps and the canopies (<i>P</i><0.05). The values of seed density with the same upper case letters do not differ significantly between the gaps and the canopies at the same time (<i>P</i><0.05). Error bars indicate means ± S.E.
