| Abstract | ||
| Competition is reflected in the strength of plant growth, production, leaf area, and depth of the root total. Over time, the number of dead individuals may increase or be reflected in the production and vitality of individuals where competition arises as a result of the similarity of the species' food, water, and light needs. The competition within and between Ceratonia siliqua and Pinus pinea trees has been measured at the rate of four treatments (1 to 5) within the species, and 5 treatments between the two species. We measured the total dry weight, dry total weight, dry root weight, seedlings diameter, and high seedlings. The results of the measurement of the competition between seedlings showed moral differences in dry total weight, dry total vegetable weight, and high seedlings, while no moral differences in dry root weight and diameter were shown. Similarly, the value correlation coefficient values of measured quantity properties of seedlings had a strong direct relationship with dry total weight. Also, the results of measurements of competition between the two species indicated significant differences in dry total weight, dry vegetable weight, and dry root weight, the mean values of all traits were higher in Ceratonia siliqua than that of the Pinus pinea, while there were no differences in the diameter and height of the seedlings. Mixing tree species is better than pure forests and may enhance growth in mixed forests. | ||
