A greenhouse experiment on the effect of different simulated tidal inundation times on the growth of mangrove Kandelia candel seedlings was conducted,and some physiological and growth indexes of the seedlings,including growth rate,biomass and chlorophyll content,superoxide dismutase,proline,malondialdehyde,peroxidase,electrical conductivity and root activity were measured.

A greenhouse experiment on the influence of simulated tidal inundation on the growth of Bruguiera sexangula var.

But there would have wrong judgment when using the rebound method to detect the intensity of the moist or water-immerged concrete,because the compressive strength of the surface of the moist or water-immerged concrete is always influenced and debased.
