“…However, in warmed plots, these positive effects on growth of P. asperata seedlings were shielded. Previous studies suggested that soil nitrogen deeply affected plant biomass allocation (Nakaji et al 2001;Grechi et al 2007). Similar with these results, nitrogen fertilization also prominently increased LMR and SMR, and decreased RMR under both warmed and unwarmed conditions.…”

Picea asperata is a dominant species in the subalpine coniferous forests distributed in eastern edges of Tibetan Plateau and upper reaches of the Yangtze River. The paper mainly identified the short-term influences of experimental warming, nitrogen fertilization, and their combination on growth and physiological performances of Picea asperata seedlings. These seedlings were subjected to two levels of temperature (ambient; infrared heater warming) and two nitrogen levels (0; 25 g m -2 a -1 N) for 6 months. We used a free air temperature increase of overhead infrared heater to raise both air and soil temperature by 2.1 and 2.6°C, respectively. The temperature increment induced an obvious enhancement in biomass accumulation and the maximum net photosynthetic rate, and decreased AOS and MDA level under ambient nitrogen conditions. Whereas, negative effects of experimental warming on growth and physiology was observed under nitrogen fertilization condition. On the other hand, nitrogen fertilization significantly improved plant growth in unwarmed plots, by stimulating total biomass, maximum net photosynthetic rate (A max ), antioxidant compounds, as well as reducing the content of AOS and MDA. However, in warmed plots, nitrogen addition clearly decreased A max , antioxidant compounds, and induced higher accumulation of AOS and MDA. Obviously, the beneficial effects of sole nitrogen on growth and physiology of Picea asperata seedlings could not be magnified by artificial warming.

“…Furthermore, Merlot vines grown in the highest N condition had a larger individual leaf area than the lowest N condition that markedly reduced leaf area [31]. A linear relationship between leaf area and N amount especially when combined with K, this may reflect the role of N as constituent of amino acids and protein as well as the important role of K in promoting cell division and development of meristimatic tissue [32]. increased vine leaf area, photosynthesis, transpiration and stomatal conductance of 'Muller Thurgau' grapevines [33].…”

The effect of the nutritional status of grapevine 'Crimson Seedless' on growth, fruit set and quality was studied in two growing periods. The vines were treated with three nitrogen rates (24, 36, 48 kg/ha.) combined with three potassium levels (240, 285, 330 kg/ha). Increasing N supply enhanced N-concentrations in the petioles. N-fertilization also increased K concentrations in the petioles. The K-fertilization variants themselves did not alter the K content of the petioles. High Nfertilization improved vegetative growth (leaf area, cane diameter) and reduced bud burst, bud fertility and fruitfulness. Excessive N-supply negatively affected yield per vine by reducing the number of fruit clusters. Cluster size, however, was improved with increasing N-nutrition whereas the number of berries per cluster and the cluster compactness remained unchanged. The single berries were bigger (size, weight) and their shape remained typically for the cv. The amount of juice per berry increased and fruit firmness decreased in the high N-variants. The only effect of high K fertilization was an increase of total soluble solids and a decrease of acid concentration. Anthocyanin contents generally showed a high variability in the experiment. Therefore, the color of berries might be more regulated by the ripening process than by the fertilizer treatments.

“…Soluble sugars (reducing sugars and Suc) and starch were analyzed enzymatically (kit LISA 200C; CETIM) after sequential extraction with an ethanol:water mixture (80:20, v/v) at 60°C. The NADPH2 released by the enzymatic reactions was measured spectrophotometrically at 340 nm with an absorbance microplate reader (ELx800UV; Bio-Tek Instruments; Grechi et al, 2007).…”
