Physiological and biochemical characteristics of Camellia oleifera during root cutting establishment
Abstracts:The aim of this study was to determine the soluble protein content,soluble sugar content,and peroxidase (POD)activity for two Camellia oleifera cultivars (XL1 and XL4)during root cutting establishment.The content of soluble proteins was detected by coomassie brilliant blue method,soluble sugar content was detected by anthrone colorimetry,and the POD activity was detected by guaiacol method.Results showed that rooting of C.oleifera was derived from the callus.Also,during root cutting establishment the content of soluble proteins and soluble sugars for XL1 was higher than XL4,and soluble protein content increased first,decreased later,and then increased rapidly.Soluble sugar content first increased and then decreased.Additionally,POD activity of XL4 was higher than XL1 reaching a peak during the callus formation phase and the adventitious root induction phase,which was beneficial to the induction of root primordia.POD activity decreased during the expression period of callus and adventitious roots,which was beneficial to the growth of root primordia and elongation of adventitious roots.
