| Abstract | ||
| Rapid early growth of poplars established from hardwood cuttings is critical to the success of Poplar cultivations. Without rapid growth,weed competition can significantly affect tree survival and productivity. The effects of cutting age and planting depth on early survival, growth and biomass of Populus deltoides clone 69/55 were studied in cold frame test in Guilan province. Results showed that early survival, aerial biomass, leaf and shoot dry weight, shoot number and length and finally root to shoot ratio (r/s) were significantly affected by cutting age. Planting depth only affected aerial biomass and shoot dry weight, however had no significant effect on the other variables. This study found that one year old cuttings planted about two third length deep, are preferable for vegetative propagation of Eastern cottonwood by cuttings. | ||
