Abstract:
To better understand the environmental adaptability of Rubus chingii from Dexing，Jiangxi，the anatomical characters of its vegetative organs were studied with optical microscope，paraffin section，freehand section.The results showed that the secondary structure of the roots with developed secondary xylem and developed phellem layer were observed.The developed secondary xylem was helpful for adding the roots’ ability to transport mineral nutrients and water.And the developed phellem layer could protect roots internal organization from heat injury to increase roots’ drought tolerance.It was observed that there were lots of xylem parenchyma cells，wood rays，phloem rays and phloem parenchyma cells in the secondary structure of the roots where reserving nutrition substance.Vessel element was not only big diameter but also multiple quantity in the secondary structures of the stem；the developed pith was in the center of stem.Leaf was typical bifacial，the upper epidermal cells were neatly arranged closer；rare stomata were observed on upper epidermis.More stomata distributes under epidermal.There was developed palisade tissue and spongy tissue in leaf.The structure of the raspberry leaf showed the sun leaves.
