PHOTOSYNTHESIS RATE COMPARISON BETWEEN AGE CLASSES Eucalyptus Sideroxylon A. Gunn, PLANTS IN ABSHERON PENINSULA

This study aimed to investigate the photosynthesis rates of Eucalyptus sideroxylon A. Gunn. leaves over a year using the Plant Photosynthesis Meter 3051C. The photosynthesis rates of juvenile, mature, and aged leaves were measured at least three times a month during mid-morning. The results showed that there was a significant difference in photosynthesis rates among the different age classes, with aged leaves exhibiting the highest photosynthesis rate and mature leaves exhibiting the lowest. The study found that there were seasonal patterns in photosynthesis rates, with the highest rates observed during summer and the lowest during winter. These findings suggest that environmental factors such as temperature and geography of area may play role in determining the photosynthesis rates of Eucalyptus sideroxylon A. Gunn. leaves. Overall, this study provides important insights into the factors that influence the photosynthesis rates of this species and could be useful in informing future research and management strategies
