“…Carbon isotope discrimination reflects the time‐integrated intercellular concentration of CO 2 , and the positive effect of N supply on δ 13 C has been widely observed (see Introduction). Higher δ 13 C values in crops receiving mineral N than in non‐fertilised crops indicate a higher photosynthetic capacity 34, 35. Jenkinson and co‐authors reported that there was a large difference between δ 13 C in N‐fertilised and non‐fertilised plants, but they only compared low and high N supply, whilst we compared four mineral nitrogen rates (plus a zero N and a manure treatment) 4.…”

The Broadbalk Wheat Experiment at Rothamsted Research in the UK provides a unique opportunity to investigate the long-term impacts of environmental change and agronomic practices on plants and soils. We examined the influence of manure and mineral fertiliser applications on temporal trends in the stable N ( 15 N) and C ( 13 C) isotopes of wheat collected during 1968-1979 and 1996-2005, and (1968)(1969)(1970)(1971)(1972)(1973)(1974)(1975)(1976)(1977)(1978)(1979). We conclude that, in addition to fertiliser type and application rates, water stress and, importantly, plant variety influenced plant d 13 C and d 15 N values. Hence, water stress and differential variety response should be considered in plant studies using plant d 13 C and d 15 N trends to delineate past or recent environmental or agronomic changes.

“…Cuartero and Fernández-Muñoz (1998) observed a reduction in the dry mass of tomato stems, leaves and roots under conditions of salinity. The high concentration of ions in soil can lead to an imbalance in the water and ion potential at the soil-plant interface and can be toxic to the plant, thus affecting its growth and phytomass production (Asch et al 2000) due to the reduction in the absorption of mineral nutrients such as potassium, calcium and manganese (Lutts et al 1999). Figure 4 shows the xylem matric potential (Ψ w ) of maize leaves at 30 (a and b) and 75 (c and d) days after planting according to the different proportions of calcium silicate and irrigation depths.…”

ABSTRACT:The aim of this study was to evaluate the potential of calcium silicate to mitigate the effects of water deficiency in maize plants yield. A completely randomized factorial design, consisting of five combinations of calcium silicate (0, 25, 50, 75, and 100%) and five different soil moisture levels (30, 70, 100, 130, and 160%), was adopted.The following parameters were evaluated: soil matric potential, xylem water potential, silicon concentration, leaf dry weight, and dry mass

“…Growth response to salinity is often regarded as a useful basis for evaluation of resistance, and it has been reported that salt-tolerant cultivars have a smaller reduction in dry matter compared with salt-susceptible cultivars [22,23]. In this study, when salinity was 12 dS/m in the tillering stage, salinity-tolerant Pokkali showed a smaller decrease (18.2%) in total dry mass than Nikomaru (56.0%) and Koshihikari (63.2%) compared with the plants under 6 dS/m salinity.…”

Salinity is an abiotic stress that curtails rice production in many parts of the world. Although Koshihikari and Nikomaru are high-yielding japonica rice cultivars, their salinity-tolerance levels are not well known. This experiment was conducted in Ehime, Japan to assess the effect of salinity on ion accumulation and dry mass production of Koshihikari and Nikomaru compared with a salinity-tolerant indica rice cultivar (Pokkali). Control (0.16 dS/m), 6 dS/m and 12 dS/m irrigation treatments were conducted during the tillering stage (1st phase of experiment), and later only control and 6 dS/m irrigations were applied during the reproductive stage (2nd phase of experiment). Excessive Na+ accumulation in plants hampers the uptake of the macronutrients K+, Ca2+, and Mg2+, which consequently retards growth and yield. Because salinity-tolerant plants can avoid this stress, minimal Na+ was found in Pokkali during the tillering stage (under 6 dS/m salinity). Additionally, Nikomaru showed better growth and dry mass than Koshihikari. Moreover, the Koshihikari leaves contained more Na+ than Nikomaru and Pokkali. The japonica cultivars had higher Na+/K+ in their leaves than Pokkali. In the reproductive stage, the two japonica cultivars accumulated almost the same amount of Na+ under 6 dS/m salinity. However, under 6 dS/m salinity, the grain yield of Nikomaru was higher than control, whereas that of Koshihikari decreased because of salinity. Meanwhile, Pokkali had the lowest Na+/K+ in the whole plant, and most parts of Nikomaru showed lower Na+/K+ than Koshihikari. Koshihikari was relatively less tolerant than Nikomaru under 6 dS/m salinity during both stages, while both failed to withstand 12 dS/m.
