查询词典 rootstock

The ungrafted cucumber plants used as controls,the effects of grafting with different scions on cucumber growth and physiological trait were investigated by using \'Zaoduojia\' and \'Jinchun No.2\' as scion,and \'Chaojiquanwang\' as rootstock under NaCl stress.

采用'早多佳\'和'津春2号\'黄瓜品种作接穗，耐盐的'超级拳王\'作砧木嫁接，以自根苗为对照，对不同接穗嫁接黄瓜苗在盐胁迫下的生长及生理特性进行了测定。

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。

The hydrogen is produced by the reaction of Al and autoecious mechanism during anode effect dealing process, which has important effect on the formation of Al electrolyte. Hydrogen produced in the course of Al electrolysis pollutes aluminum liquid by diffusion and autoecious mechanism is the main rootstock affecting the metallurgical quality of liquid-Al in short-flow process.
