Abstract: Investigation was conducted to analyze the effect of management measures such as trunk cutting and fertilization on frost resistant capability of young paulownia (Paulownia sp. ) plantation which had been undergone heavy frost damage in early 2008 in southern China. Experimental sites were located in the Paulownia fortunei forest consisting of 2-poplar clonal plantations in Chaling County. Paulownia fortunei, treated by root planting, trunk cutting and fertilization was called 2B; the contrast was called 1B. The results showed that the tree height, DBH, height under branch and lateral branch diameter in 2B were, respectively, 19.19%, 11.36%, 180% and 13.8% higher than those in 1B. The number of lateral branches in 1B was 2.8 times that in 2B. The icicle pressure beared by 2B was only 60.21% of that in 1B. There was nearly no potential damage in the 9treatment plot with 98% of the plants in the freeze injury grade I. In contrast, 50% and 36% of the plants in the control plot were observed, respectively, in freeze injury grades II and Ⅲ. Based on the present investigation, it can to be concluded that the applied management measures are effective in enhancing the resistant capability of young poplar plantations to frost damage.
