The results showed that:Under NaCl stress,the reductions in the shoot and root dry weight, leaf area,stem diameter of grafted plant were lower than those of ungrafted plants.The Na~+ content,Na~+/K~+ ratio,Na~+/Ca~(2+) ratio in the leaf and scion stem of grafted plants were lower whereas those of in the rootstock stem ad root were higher than in ungrafted plants. The K~+ contents,soluble sugar contents,shoot water contents,SOD,POD,CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance were higher,whereas the MDA contents in the leaf of grafted plants were lower than that in ungrafted plants.The reductions in leaf area and stem diameter of grafted \'Jinchun No.2\' plants were more severe than those of grafted \'Zaoduojia\' ones.

结果表明，盐胁迫下，嫁接苗地上部和根干重、叶面积、茎粗降低的程度显著低于自根苗；嫁接苗叶片和接穗茎中Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著低于自根苗，而砧木茎和根中的Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著高于自根苗；嫁接苗叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗，MDA含量显著低于自根苗。

For assisting identification of crude drug Herba Dendrobii. Methods Morphological and histological studies were carried out on 11 medicinal plant roots in Dendrobium Sw. by microstructural observation. The 11 species were divided into three groups according to their stem morphology: a pair fleshy-stem group, including D. chrysanthum, D. crepidatum, D. primulinum, D. hercoglossum, and D. crystallium; b thick-and rigid-stem group, including D. fimbriatum and D. aurantiacum var. denneanum; c node-or inter- node- bulgy-stem group, including D. findlayanum, D. gratiosissimum, D. pendulum, and D. wardianum. The surface descriptions of velamen were conducted for D. fimbriatum and D. aurantiacum var. denneanum which are similar in characters of cross section.

The results showed that: Under salt stress, it was found the content of Na(superscript +), Cl(superscript -), SO(superscript 2- subscript 4) and Na(superscript +)/K(superscript +) ratio in almond rootstocks organs all went up with increased salt stress and longer treatment days, K(superscript +) content changed irregularly. But K(superscript +) content in every organ of A. commans persicoides rootstocks was higher than that of other two almond rootstocks; the ratio of Na(superscript +)/K(superscript +) in Amygdalus communis L. was higher than that of other two rootstocks.
