Abstract:Paraffin section is one of the most direct and effective way to observe plant and animal tissues. We sliced rice leaf of 9 311 and stained with 1% Safranin-ethanol solution and Aniline blue-ethanol solution. The organization of our improvement is more complete than traditional paraffin, stained effect is more clearly than traditional method, and sliced rice leaf in this method can significantly shorten the rehydration and dehydration time in the late production and improved work efficiency.
