The apoplasmic charater of ectomycorrhizal roots of Larix seedlings infected with Paxillus involutus was examined using the cathnic colloidal gold. The result showed the density and distribution of anionic binding sites were different in sheath and Hartig net. The negative charger in the outer part of the sheath was slightly low. It increased graduately from outer to inter sheath. The negative charger density rised higher in the inter part of the sheath and then decreased graduatedly from the sheath to Hartig net. This may be related to nutrient uptake and atransport in ectomycorrhizal roots.

And the Si peak value and content of 91SP\'s leaf sheath inside were more than those of Lemont obviously. After being inoculated with R.solani, the sheath blight occurrenced in 91SP and Lemont, but hypha on surface of siliceous cells were few, the hypha number of 91SP\'s leaf sheath inside were obviously less than Lemont, and sclerenchymatous cell\'s wall thickness of Lemont leaf in Si+ rice plants was about 2 times to Si- rice plants.

CO2 and H2S exist in the hydrocarbon zone and foramtion water,as the accompany gases of petroleum and nature gaso or components of formation water,which will cause corrostion to the cement sheath under certain conditions of humidity and pressure.It will decrease the cement sheath's alkalinity,which results in the decrease of cement sheath's strength,permeability increase,and places a premium on fluid channeling and borehole wall sloughs accident in plastic formation,shortening the oil- gas well's production lifetime and giving rise to tremendous ecomonic losses.
