Abstract: 【Objective】 To determine the ecological adaptive capacity and rooting type of Portulaca oleracea L. for its better develop and utilize.【Methods】 The anatomical vegetative organs and cuttings rooting were observed by paraffin section.【Results】 The roots and stems of purslane were stout and contained more parenchyma.The root had secondary structures such as pericarp and secondary vascular tissue,and xylem was well developed.There were scattered vascular bundles in the stem,and cortex and marrow were more developed.The leaves were typical heterofacial,with mucinous cells,and the main veins were arranged with two external tough vascular bundles.There were annular fiber bundles outside petiole and main vascular bundle.Crystals were found in parenchyma cells of roots,stems and leaves.Adventitious roots of stem cuttings originated from parenchyma cells near the interfascicular cambium or phloem.【Conclusion】 The vegetative organs of Portulaca oleracea L. had the characteristics of resistance to dry and salt.The root of stem cuttings was the original type of inducing root and easy to take roots.
