Information on the homogeneity and distribution of 13carbon (13C) and nitrogen (15N) labeling in winter wheat (Triticum aestivum L.) is limited. We conducted a dual labeling experiment to evaluate the variability of 13C and 15N enrichment in aboveground parts of labeled winter wheat plants. Labeling with 13C and 15N was performed on non-nitrogen fertilized (−N) and nitrogen fertilized (+N, 250 kg N ha−1) plants at the elongation and grain filling stages. Aboveground parts of wheat were destructively sampled at 28 days after labeling. As winter wheat growth progressed, δ13C values of wheat ears increased significantly, whereas those of leaves and stems decreased significantly. At the elongation stage, N addition tended to reduce the aboveground δ13C values through dilution of C uptake. At the two stages, upper (newly developed) leaves were more highly enriched with 13C compared with that of lower (aged) leaves. Variability between individual wheat plants and among pots at the grain filling stage was smaller than that at the elongation stage, especially for the −N treatment. Compared with those of 13C labeling, differences in 15N excess between aboveground components (leaves and stems) under 15N labeling conditions were much smaller. We conclude that non-N fertilization and labeling at the grain filling stage may produce more uniformly 13C-labeled wheat materials, whereas the materials were more highly 13C-enriched at the elongation stage, although the δ13C values were more variable. The 15N-enriched straw tissues via urea fertilization were more uniformly labeled at the grain filling stage compared with that at the elongation stage.

Simultaneous Inhibition

BASF 13-338, a derivative of pyridazinone, inhibits photosynthesis without affecting. respiration in winter wheat (Triticum aestivum L.) at low temperature. This inhibition could account for the previously reported inhibition of frost hardening. Therefore, simultaneous inhibition of linolenic acid accumulation and of frost hardening are probably not causally related.

Assessment of winter wheat (Triticum aestivum L.) grown under alternate furrow irrigation in northern China: Grain yield and water use efficiency. Can. J. Plant Sci. 94: 349–359. Increasing water use efficiency (WUE) can improve agricultural production in the north of China, where there is little or no prospect for the expansion of water resources. A field experiment was carried out to investigate the effects of alternate furrow irrigation (AFI) on the physiological response, grain yield, and WUE of winter wheat (Triticum aestivum L.) over two successive growing seasons (2009/2010 and 2010/2011). The irrigation regimes were: W0, non-irrigated; W2, every furrow was irrigated at jointing and anthesis; W3, every furrow was irrigated before wintering and at jointing and grain filling; and AFI, where one of the two neighboring furrows was alternately irrigated before wintering and at grain filling, and every furrow was irrigated during jointing. Our results indicate that the rate of plant transpiration and soil evaporation during grain filling were lower with AFI than when using W3. A reduced biological yield and increased harvest index were achieved under AFI compared with treatment W3. No difference in grain yield was observed between AFI and W3. The photosynthetic WUE, irrigation WUE, and WUE were all higher with AFI than with W3. Therefore, AFI is suggested as an appropriate irrigation schedule that achieves acceptable grain yields and allows for reductions in irrigation water consumption.

Winter wheat (Triticum aestivum L.) was grown in methyl bromide fumigated and nonfumigated soils in the field. Fumigation increased growth of wheat in the winter but depressed growth later in the spring. Growth depression of winter wheat in fumigated soils coincided with VAM-fungal colonization of wheat roots in nonfumigated soils. In the spring, wheat plants growing in fumigated soils were more chlorotic than those in nonfumigated soils. Plants grown in fumigated soils produced 18–21% less aboveground biomass during grain filling, and 42% less grain at final harvest than controls. In May, photosynthesis, stomatal conductance, and transpiration of flag leaves were reduced 40–52, 41–55, and 24–36%, respectively, in fumigated plots when compared to nonfumigated plots. Wheat was colonized by VAM only 20% of the growth period; however, VAM colonization may occur at a period critical to grain production of winter wheat.Key words: Triticum aestivum, fumigation, mycorrhizae, photosynthesis, water relations, wheat (winter)
