Turkish Journal of Agriculture and Forestry
Camellia sinensis L. is one of the most economically important crops in the world today. The leaves of this plant are harvested for tea production on a massive scale through a process that requires a large amount of inorganic nitrogen (N). However, knowledge of how inorganic nitrogen regulates the growth physiology of C. sinensis L. remains limited. In order to investigate its effects on gas exchange, N assimilation, and the efficiency of N use in C. sinensis L., we carried out experiments with 4 cultivars (WNZ, YS, ZN139, and LJ43) under 4 different treatments: 1) a control treatment, 2) a …

N-acetylcysteine (NAC) biosynthesized reduced glutathione (GSH), which maintains redox homeostasis in plants under normal and stressful conditions. To justify the effects of NAC on rice production, we measured yield parameters, chlorophyll (Chl) content, minimum Chl fluorescence (Fo), maximum Chl fluorescence (Fm), quantum yield (Fv/Fm), net photosynthesis rate (Pn), photosynthetically active radiation (PAR), and relative water content (RWC). Four treatments, N1G0 (nitrogen (N) with no NAC), N1G1 (N with NAC), N0G0 (no N and no NAC), and N0G1 (no N but with NAC), were arranged in a completely randomized design with five replications. Nitrogen significantly increased yield and yield parameters of …

Turkish Journal of Agriculture and Forestry
The impact of pretreatment with high temperature (45 °C for 45 min) on the UV-B tolerance of 4 barley cultivars (Hordeum vulgare L. 'Bülbül-89', 'Kalaycı-97', 'Tarm-92', and 'Tokak-157/37') was examined. The response of the plants to treatment was evaluated by measuring the pigment content, chlorophyll a fluorescence, oxygen evolution, fraction of oxygen-evolving complex, proline content, UV-B-absorbing compounds (A_{535} and A_{300}), and stress markers (malondialdehyde, H_2O_2, and UV-B marker). Regardless of high temperature pretreatment, UV-B irradiation decreased the photosynthetic pigment content, photosystem II activity, oxygen evolution, and the fraction of oxygen-evolving complex in almost all of the barley cultivars. UV-B treatment …

Plant Water Relations And Photosynthetic Activity In Three Tunisian Chickpea (Cicer Arietinum L.) Genotypes Subjected To Drought, Abdelmajid Krouma
Turkish Journal of Agriculture and Forestry
Chickpea (Cicer arietinum L.) is an important food crop grown under rainfed conditions in Mediterranean regions in which drought is a major limiting factor for production. In these areas little attention is given to legumes, and efforts to identify drought-tolerant genotypes are primarily focused on major cereal crops. In the current study a greenhouse experiment was conducted to assess the effects of drought stress on plant growth, photosynthesis, and water relations in 3 Tunisian chickpea genotypes (Cicer arietinum L.). Drought was applied, and soil humidity was maintained at 30% of field capacity (stressed plants) or 100% of field capacity (control …

Turkish Journal of Agriculture and Forestry
Growth and essential oil content of peppermint (Menhta piperita var. officinalis) and lemon verbena (Lipia citriodora var. Verbena) were evaluated in response to salinity and nutrient solution concentrations, measured as electrical conductivity (EC 0.7, 1.4, 2.8, 5.6, and 5.6_{Na} dS m^{-1}). In peppermint, the highest fresh weight and dry weight were observed in the 1.4 dS m^{-1} treatment. The increased EC with either NaCl or all nutrients at 5.6 dS m^{-1} reduced the fresh weight of lemon verbena. The maximum fresh weight and dry weight in lemon verbena were obtained in both 1.4 and 2.8 dS m^{-1} treatments. Increasing EC …
