摘要: 【目的】 确定马齿苋的生态适应能力和生根类型,从而更好地开发和利用。【方法】 采用石蜡切片法对马齿苋营养器官及扦插生根进行解剖学观察。【结果】 马齿苋的根和茎粗壮,含较多的薄壁组织;根具有周皮和次生维管组织等次生结构,木质部发达;茎中有散生的维管束,皮层和髓发达;叶为典型的异面叶,有黏液细胞,主脉为2个外韧型维管束相对排列;叶柄及主脉维管束外有环状纤维束;根、茎、叶的薄壁细胞中含有晶体;茎扦插产生的不定根起源于束间形成层或韧皮部附近的薄壁细胞。【结论】 马齿苋营养器官具有抗旱、抗盐碱的解剖特征,茎扦插生根为诱生根原始体类型,且易生根。

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.
