Effect of Drought and UV-B Stress on Leaf Morphology of Ash-Leaved Maple and Sycamore Maple

Global climate change continues to leave irreversible effects worldwide. With the increase in of change, especially recent years, amount UV-B radiation reaching earth's surface is also likely increase. increasing temperatures, precipitation world has decreased, and drought started alarm. This study tried understand how plants can respond these stresses using ash-leaf maple (Acer negundo L.) sycamore pseudoplatanus species. The stress factors on plant leaf morphology were investigated by applying certain intensities (moderate [T2] severe [T3]) (8 kJ m-2 h-1 [T4] 12 [T5]) two species with T1 (control) treatment. As a result, width A. was at lowest levels individuals exposed T3 T9. In species, leaflet length T1, T2, T3, T4 T5, T6 (modarete+T4), T7 (modarete+T5), T8 (severe drought+T4), T9 drought+T5) treatment 8.800, 8.704, 8.075, 8.792, 8.823, 8.516, 8.317, 7.993, 8.605 cm, respectively. According values, it observed that shortest (7.993 cm) On other hand, close group. more affected than T5 applications applied T3. Therefore, positively affects plant's resistance stress.
