Abstract The analysis of propagation coefficient and cost accounting of tissue culture of Populus alba×berolinensis showed that :the propagation coefficient of tissue culture was 7.2 × 107,which would meet the requirements for rapid propagation of tissue culture,and the cost of tissue culture was 0.231yuan per seedling,indicating that tissue culture of Populus alba×berolinensis entirely feasible for commercial production.
