Description
Abstract. -- A greenhouse experiment was conducted to determine the effect of Juniperus ashei litter on the growth and survival of J. ashei seedlings. Incremental additions (0-250 g) of J. ashei tree litter or vermiculite (control) were placed on 15 by 15 cm pots, which contained transplanted J. ashei seedlings in 800 g of mineral soil. There were no significant differences in the mean absolute differences in growth of J. ashei seedling considering basal diameter, seedling height and number of branches between the J. ashei tree litter additions and the vermiculite additions, or the amounts of both types of litter. However, there were non-significant positive increases in the seedling growth in the 50 g treatment of both litter types followed by a decrease at higher levels. Mortalities were highest at greater levels of both types of litter, but were still non-significant. The responses of the J. ashei seedlings with respect to growth and survival in the J. ashei litter and vermiculite suggest that there is no allelopathic component in the J. ashei litter affecting seedling growth and survival or if there is, it is transient. **********
