查询词典 cortex parenchyma

The plant body tends to form great deal of aerenchyma under the saline-alkali habitat.

However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.

Result:Characteristics of the tangentical longitudinal section of stem with resin and surface view of leaves were elucidated.Besides xylem vessels and fibers of the stem,it was found that the red resin also exists in the cortex parenchyma cells of the stem and the medulla and xylem of the root.According to the HPLC fingerprint analysis result of the stems with and without resin,a number of flavones and stilbenoids were detected in the stem in which resin appeared after it wounded.
