“…Heat stress and rainfall are recognized as significant factors affecting grain yield and quality in wheat. During grain-filling unfavorable climatic conditions can led to alterations in protein deposition and starch biosynthesis, and thus starch characteristics (Balla et al, 2011). Exposure to high temperatures may severely influence starch accumulation in cereal endosperm due to susceptibility of starch enzymes (Barnabas et al, 2008;Zhao et al, 2008).…”

ABSTRACT:The aim of the present paper was to evaluate the influence of different climatic conditions on the activity of alpha-amylase in wheat samples and bread quality parameters. Three wheat varieties grown in three different localities in three years were chosen for this study. Commonly used methods for estimation of alpha-amylase activity in wheat grain were employed. The obtained results indicated that harvest year 2013, which was characterized with the excessive amount of rainfall, exhibited the highest level of alpha-amylase activity and the lowest values of the peak viscosity. The lowest alpha-amylase level and the highest peak viscosity and FN value were observed for samples harvested in 2012 which was characterized with the greatest number of days with an average daily temperature above 30 and 35 °C. In addition, a decrease in Mixolab parameter torque C3 and specific bread loaf volume, as well as increase in the breakdown torque (C3-C4) of samples harvested in 2013 were observed, which could be attributed to rainy weather influencing increase in alpha-amylase activity. It is found that specific bread loaf volume of wheat samples is highest in 2012. Moreover, a negative correlation between alpha-amylase activity and specific bread volume for all the samples grown in three years was determined.

Isotopic carbon discrimination (Δ 13 C) of winter wheat grain grown under different water and nitrogen supplies was determined. In two field experiments during years 2004-2007 (A) and 2008-2013 (B), a water shortage was induced from the flowering stage on with a mobile shelter (S), while an optimal water supply was ensured with drip irrigation (I), and a rain-fed crop served as the control treatment (R). Water supply had a statistically significant effect on grain Δ 13 C values in both experiments (P < 0.01). The average values of grain Δ 13 C in treatments I, R and S were 19.43, 18.68 and 17.70‰ (A); and 20.36, 19.60 and 18.13‰ (B). Grain Δ 13 C was in a significant linear relationship (P < 0.01) with the amount of water supplied by precipitation or irrigation. The regressions suggested that grain Δ 13 C increased by 1.14‰ and 1.16‰ (A), and 0.98‰ or 0.96‰ (B) for every 100 mm of water from January and March, respectively, until the early dough stage (r = 0.79-0.74, P < 0.05). Pooled data for the whole period 2004-2013 showed increases of 1.06‰ and 1.08‰ (r = 0.91 and 0.82, P < 0.05) for 100 mm of water, respectively. The results of the experiment confirmed the stable and predictable effect of water supply on wheat grain Δ 13 C. Keywords 329Plant Soil Environ. Vol. 62, 2016, No. 7: 329-334 doi: 10.17221/118/2016-PSE was observed, especially when plants that were either under strong stress (semiarid conditions) or under irrigation were compared (Zhu et al. 2009, Misra et al. 2010. The value of Δ 13 C in seeds integrates the effects of water supply and plant water status during growth. However, this assumption about a positive correlation between yield and Δ 13 C has not always been confirmed, as the response to water shortage and the process of yield formation depends on many year-, agronomy-, and site-dependent factors during growth (Monneveux et al. 2005). Under temperate and transition (maritime/inland) climatic conditions, where precipitation during growth is highly variable, rain-out shelters enable a standardization of the water supply in the field, partially independent of that year's meteorological conditions (e.g., Yasir et al. 2013). The aim of the study was to examine the impact of water supply differentiated from anthesis, during the period of wheat grain growth upon values of Δ 13 C, to determine the relationships with water supply during growth and any possible interactive effect of nitrogen fertilization. MATERIAL AND METHODSTwo successive experiments (A and B) with differentiated water supplies during grain growth were carried out at the Crop Research Institute (CRI), Ruzyně near Prague, Czech Republic (50°05'N, 14°20'W), altitude 340 m a.s.l., average annual sum of precipitation 477 mm, and average daily temperature of 8.5 o C. The experimental field is a fertile deep loamy-clay Haplic Chernozem soil on loess. The contents of available P, K, and Mg (according to Mehlich III) were 85, 245 and 226 mg/kg dry soil in the topsoil (0-30 cm); and 10-12, 121-141 and 254-352 mg/kg in the s...

“…A more favourable nutrient supply, the increasing nitrogen fertilizer dosages -in addition to a harmonized NPK and mezo-and microelement fertilization -increased the protein and wet gluten contents of wheat, but the gluten elasticity, the falling number and the farinographic value were less affected (Jolánkai 1993, Johansson 2002, Pedersen and Jorgensen 2007, Wang et al 2009, Erekul et al 2012. The research results proved that NPK fertilization increased the farinographic value of winter wheat varieties, but the increment varied with the year (Barič et al 2004, Mikulikova et al 2009, Balla et al 2011, and the year-dependent stability of the quality was much lower under deficient or moderate NPK fertilization (Holford et al 1992). International and Hungarian experimental results proved that the baking quality parameters modified by NPK fertilization depended on genotype (Ragasits 1992, Jolánkai et al 1998, Pepó 1999, Lloveras et al 2001, so variety-specific fertilization needed in the practical management to improve the quality of wheat.…”

Abstract:In a long-term experiment, a complex study of the baking quality parameters of four modern winter wheat genotypes (GK Csillag, Mv Csárdás, Mv Toldi, GK Békés) was carried out in fertilizer treatments with increasing dosages (control, N 60 +PK, N 120 +PK) in two different years (2013 and 2014) on chernozem soil in Eastern Hungary. In the control and the N 120 +PK treatments, the protein content ranged within the boundaries of 8. 88-11.46% (in 2013) and 6.73-11.19% (in 2014) and 11.03-13.30% (in 2013) and 10.53-14.29% (in 2014), respectively. The wet gluten content values were 24.88-37.18% (in 2013) and 18.03-23.53% (in 2014) in the control and 35.30-43.16% and 33.28-39.10% in the N 120 +PK treatment. Using Pearson's correlation analysis, a tight correlation was found between fertilization and the protein content (r = 0.571**-0.739**) and between fertilization and the wet gluten content (r = 0.587**-0.859**). A medium correlation was observed between fertilization and the farinographic value (r = 0.275-0.484**) and between fertilization and gluten elasticity (r = 0.322**-0.466**). Fertilization did not have an impact on the falling number (r = -0.014-0.226). Strong correlation was found between the protein and the wet gluten contents (r = 0.817**-0.950**).
