Study on Seedling Stock Grafting of Five Varieties of 'Yunyou' Series of Camellia oleifera

From 2010 to 2011,taking five superior Camellia oleifera varieties namely 'Yunyoucha 3','Yunyoucha 4','Yunyoucha 9','Yunyoucha 13' and'Yunyoucha 14' as research objects,the variety comparison test of grafted seedlings and the treatment tests at different hormones types and concentrations were carried out.The results showed that:(1) There were no significant differences in survival rate,shoot height,shoot diameter,new-root number,average new-root length and total new-root length of grafted seedlings of five varieties,which indicated that five varieties all had good genetic propagation abilities;(2) Compared with the control(CK),survival rate,growth of shoot and root of grafted seedlings were obviously improved by ABT6,indole butyric acid(IBA) and naphthylacetic acid(NAA),but there were no significant differences between three hormones;(3) Different concentrations of different hormones had some effect on the survival of the grafted seedlings,the concentration of 200mg/L had better effect on the survival and growth of 'Yunyou' series of Camellia oleifera.
