Abstract: We compared the morphology and structure of leaf and stem from Lycium ruthenicum Murr. grown in different soil environment for introducing L.ruthenicum in Tianjin using paraffin sectioning. We measured the thick of epidermis, palisade tissue, vascular bundle, cortex and phloem of leaf and stem. The growth of L.ruthenicum in different soil conditions of Tianjin was good. The leaf of L.ruthenicum grown in alkaline clay was long lanceolate, the epidermal and vascular bundle of stem were the best developed; the leaf grown in sandy loam also was long lanceolate, but the cuticula was the thickest, the cortical of stem was the best developed; the leaf grown in red brown was long oval and more thicker, the leaf epidermal stomatal density was biggest, the epidermis was the thickest, the sponge tissue and palisade tissue of mesophyll were the best developed, the vascular bundles of petiole was the biggest, the stem was the thickest, the phloem was the most developed, and the pith was the largest. Therefore, the morphology and structure of stems and leaves of plants grown in different soil conditions were significantly different.
