Damage of Grapevine Leaf Photosynthesis by UV-B (280–320 nm) Radiation in Two Cultivars of Vitis Vinifera

Developmental stage is an important factor that determines the antioxidant responses of young and old grapevine leaves under UV irradiation in a green-house

“…Grapevine (Vitis vinifera L. cv. Chardonnay) was chosen as plant material, due to its economic importance and the sensitivity of the cultivar to UV radiation [28]. Vines are advantageous for irradiation studies, as these can be trained horizontally allowing the exposure of leaves of different ages to the same dose.…”
