Abstract:
Impatiens balsamina was conducted to study the effects of non-grafted,self-rooted grafting by the same plant seedling (SG),self-rooted grafting by two uniform plant seedlings (UG),and self-rooted grafting by two different development stages of plant seedlings (DG) on cadmium (Cd) accumulation of post-grafting generation of Impatiens balsamina under Cd contaminated condition by pot experiment.The results showed that grafting all increased the biomass,photosynthetic pigments (chlorophyll a,chlorophyll b,chlorophyll and carotenoid) contents,antioxidant enzymes (SOD,POD and CAT) activities of post-grafting generation of I.balsamina,indicating that grafting could increase the resistance of generation of I.balsamina to Cd,and promote their growth under Cd contaminated condition.Grafting also increased the Cd content,translocation factor,Cd accumulation amount and translocation amount factor of post-grafting generation of I.balsamina,and the order of these items all were ranked as DG>UG>SG>non-grafted treantment.Compared with un-grafted treantment,the Cd accumulation in roots of SG,UG and DG increased by 34.13%,63.49% and 89.22%,respectively,and in shoots increased by 55.39%,105.92% and 171.58%,respectively.Therefore,self-rooted grafting could promote the growth and improve the Cd absorption and accumulation of generation of I.balsamina under Cd contaminated condition,which improved the remedy ability of I.balsamina to Cd contaminated soil,and DG was the best one.
