) at light on cucumber and peppermint leaves were studied. A considerable decrease of the most important chlorophyll fluorescence parameters values mainly in the cucumber leaves, compared to the control, was observed. It indicates damages as well as at a donor and acceptor side of photosystem II, specially in the oxygen evolving complex, electron transport and connected with the dark reactions. In the peppermint leaves these values were unchanged or slight decreased. After 24 h from disappearing of the applied UV-B stress, adverse changes became established, especially in the cucumber leaves show irreversible damages of photosystem II. Coefficient of nonphotochemical quenching increased by 50% in the peppermint leaves, while in cucumber remained unchanged. Chlorophyll delayed luminescence coefficient was decreased by 36% in the UV-B irradiated cucumber leaves and by 25% in the peppermint leaves. Content of ultraviolet-absorbing compounds was higher in peppermint leaves by 78% than in the cucumber. Generally, peppermint seemed to be more tolerant to the applied UV-B radiation compared to cucumber. K e y w o r d s: ultraviolet-B, leaves, cucumber, peppermint, photosynthesis reactions

“…This biomass reduction in plants may be a plant's protective response to UV (Smith et al, 2000). Strong UV, however, sometimes causes UV damage to the plants such as leaf abscission, necrosis, and wrinkling (Kwon et al, 2003;Strid et al, 1994;Yao et al, 2006). UV damage mainly induces the accumulation of reactive oxygen species (ROS), which could impinge on membrane damage , PS2 activity (Yao et al, 2006), and photosynthetic pigments (Jansen et al, 1998).…”

The objectives of this study were to determine the effects of UV spectra (broad UV 274-400 nm, B-UV or filtered UV 286-400 nm, F-UV) and irradiation timing (at day or night) on growth inhibition and seedling injury in plugtransplants of pepper (Capsicum annunm L. 'Nogkwang') and tomato (Solanum lycopersicum, 'Pinktop'). We investigated some parameters, to clarify the plant response, such as ion leakage, lipid peroxidation, chlorophylls, careotenoids, photochemical efficiency, UV absorbing compound, plant growth, and flowering. The results showed that irradiation of B-UV at night significantly inhibited plant height and total leaf area in two species. However, it caused seedling injuries such as leaf necrosis and bloomlessness regardless of irradiation timing. While irradiation of F-UV did not cause any seedling injury regardless of irradiation timing, it significantly inhibited plant height by 25.4% in pepper and by 26.1% in tomato. Our results suggest that irradiation of F-UV at night may be desirable to control excessive stem elongation in plug-transplants during summer, in addition to being safe to the grower.

“…Although UV-A is less damaging per photon than UV-B, UV-A comprises a much larger portion of the solar spectrum than UV-B, and UV-A is able to penetrate to greater depths within the leaf than UV-B (Liakoura et al, 2003). UV-A can cause oxidative damage (Yao et al, 2006) and growth inhibition (Krizek and Chalker, 2005) in higher plants. Tropical countries like India receive a large amount of solar UV-B, which influences plant growth and development.…”

The influence of ambient solar UV-A or UV-B radiation on growth responses was investigated in three varieties of cotton (Gossypium hirsutum L.) after exclusion of solar UV-A/B radiation: JK-35, IH-63 and Khandwa-2. Cotton plants were grown from seeds in UV-exclusion chambers lined with selective UV filters to exclude either UV-B (280-315 nm) or UV-A/B (280-400 nm) from the solar spectrum under field conditions. Excluding UV-B and UV-A/B significantly increased plant height, leaf area and dry weight accumulation in all three varieties of cotton. The varieties differed considerably in their sensitivity to ambient UV-A/B. Khandwa-2 was most sensitive and JK-35 least sensitive to ambient solar UV. We monitored the activity of the antioxidant enzymes superoxide dismutase (SOD), ascorbic acid peroxidase (APX), glutathione reductase (GR) and guaiacol peroxidase (GPX), as well as the level of the antioxidant ascorbic acid (ASA), in primary leaves of the most UV-sensitive variety (Khandwa-2). The level of UV-B-absorbing substances was significantly decreased by exclusion of solar UV-B and UV-A/B. Exclusion of solar UV decreased the activity of all the antioxidant enzymes monitored and the level of ascorbic acid versus control plants (+UV-A/B) grown under filters transparent to solar UV. Reduction of the antioxidant defense after UV exclusion indicates that ambient solar UV exerts significant stress and induces some reactive oxygen species to accumulate, which in turn retards the growth and development of cotton plants. Ambient solar UV stresses cotton plants, shifting their metabolism towards defense against solar UV. Exclusion of solar UV eliminates the need for that defense and leads to enhancement of primary metabolism.K Ke ey y w wo or rd ds s: : Antioxidant enzymes, cotton, sensitivity index, UV exclusion.
