    實驗研究的兩種菊科( compositae )植物(準噶爾沙蒿( artemisiasongaricaschrenk )和沙漠絹蒿( seriphidiumsantolinum ( schrenk ) poljak . ) ) ,形態解剖方面的變化表現為:隨日齡增加,根長/株高比值日益增大;根系逐漸發達;體積與葉面積比逐漸增大;表皮細胞體積變小;角質層增厚;根外部出現加厚的木栓層;氣孔下陷;葉、莖部的表皮毛密布,柵欄組織日益發達;而細胞間隙日漸變小;海綿組織逐漸消失;葉面結構常為典型旱生結構? ?等葉面;晶細胞及纖維細胞數目增多;輸導組織、機械組織日漸發達;具有維管束鞘等等。
  2. Light intensity, nutrient availability and salinity all have significant effects on clonal growth and clonal morphology of h. ruthenica. deep shade, low nutrient availability and high salinity markedly reduced its growth. moreover, the degree and pattern of plasticity in biomass, leaf area, number of ramets, stolon length, petiole length and root to shoot ratio in response to salinity demonstrated genotypic variation
