播种期对新疆啤酒大麦农艺性状与蛋白质含量的影响 总被引：1，自引：0，他引：1
为确定新疆啤酒大麦优质高产栽培的适宜播种期,选用甘啤4号、垦啤7号、新啤4号、新啤8号作为试验材料,设置4月9日、14日、19日、24日、29日5个播种期,研究不同播种期对4个品种啤酒大麦产量与蛋白质含量的影响。结果表明:甘啤4号、垦啤7号、新啤4号、新啤8号这4个品种在4月份播种均能正常成熟,播种早的生育期长,播种晚的生育期短。从生育期天数来看,新啤4号新脾8号甘啤4号垦啤7号,随着播种期的推迟产量逐渐降低,蛋白质含量逐渐升高。建议甘啤4号和垦啤7号等中晚熟品种适期进行早播。 相似文献

Pre-harvest sprouting (PHS) is common in cereals that lack grain dormancy if maturing grain is exposed to rain. This phenomenon leads to immediate loss of seed viability, and since the malting process requires germination, its occurrence is highly undesirable in malting barley crops. Dormancy release rate is genetically and environmentally controlled. We evaluated the effect of temperature during grain filling on the dormancy release pattern (and then on the PHS susceptibility) of grains from five malting barley (Hordeum vulgare L.) cultivars widely sown in Argentina, with the aim of predicting PHS susceptibility of a barley crop from easy-to-gather data. Barley cultivars (Quilmes Ayelén, Q. Palomar, Q. Painé, B1215 and Scarlett) were sown on different dates over a 3-year period for generating variability in the thermal environment during grain filling. The period from pollination to physiological maturity (PM) was adjusted to a thermal time (TT) scale, which was then arbitrarily divided into 50 °C d intervals. Mean air temperature within each interval and for the whole filling period was calculated for the different sowing dates. Dormancy release pattern was followed by determining a weighed germination index (GI) throughout grain filling and maturation. We sought a linear relationship between temperature during grain filling and GI at some moment after PM. For all barley cultivars, except B1215, a significant (p < 0.001) and positive correlation was found between the GI of grains with 10–20% moisture content (fresh basis) and mean temperature within TT intervals located at the last stages of seed development. Then, simply temperature-based models for predicting crop PHS susceptibility were generated for each barley cultivar. Moreover, we intended a single, universal prediction model constructed with data from all cultivars. Two general forms were proposed, but the relationships were slightly less tight when each barley cultivar model was used. A preliminary validation for each cultivar model was done for three genotypes with independent data from four sites of the major barley production area in Argentina. When comparing experimental and field data regressions we did not find significant differences in slope for any cultivar (p > 0.25). However, most of the observed GIs were higher than predicted. This upwards displacement of GI–temperature relationship suggests the role of other environmental factors (i.e. water and soil N availability, day length), differing among tested locations. We are currently evaluating and quantifying the effect of these factors with the aim of improving PHS susceptibility prediction in malting barley crops. 相似文献

The present study has investigated the individual and combined influence of pre- and post-anthesis temperatures and cultivars on the protein composition in barley grains. Two barley cultivars were grown in soil and hydroponic systems in daylight chambers with different pre- and post-anthesis temperatures. Size exclusion (SE)-HPLC was used to evaluate the protein composition in mature barley grains. The results showed that individual and interactive effects of pre- and post-anthesis temperatures and cultivar variations influenced protein composition in the barley grains. Pre-anthesis temperature greatly affected the amounts of total sodium dodecyl sulphate (SDS) extractable proteins (TOTE) and explained 30% of the variation in TOTE. The barley cultivars accounted for 20% of the variation in TOTE. Variation in malting barley cultivars was found to influence the SDS extractable small monomers (41% of the variation). Percentage of SDS un-extractable polymeric proteins in total amount of polymeric proteins (%UPP) was governed by post-anthesis temperature, accounting for 11% of the variation and cultivar differences accounted for 7% of the variation. Thus, the climatic conditions during the specific growing period and a choice of cultivars played a major role in determining the protein composition and ultimately the malting quality of spring barley. 相似文献

The contribution of grain protein to the malting quality of barley (Hordeum vulgareL.) was investigated by comparing the hordein composition and the malting quality in barley produced under a range of field conditions. Two malting cultivars, Schooner and Arapiles, and one feed cultivar, Galleon, were grown under five nitrogen regimes in each of two years. Hordein composition of the grain was determined at maturity using a combination of sodium dodecyl sulphate-polacrylamide gel electrophoresis and laser densitometry. Malt extract was determined on all samples after micromalting. Variation in growth conditions resulted in a wide range of grain protein contents and malt extract values, as well as variation in the proportions of the individual B, C and D hordeins in the grain. D hordein in particular varied over a 10-fold range. High levels of all protein fractions were associated with low malt extract. Total protein, as expected, displayed a strong, negative correlation with malt extract. The relationship was cultivar specific and separate regression lines were generated for each cultivar. Of the individual hordein fractions, D hordein displayed the strongest negative correlation with malt extract and its relationship to malt extract was independent of cultivar. A consistent relationship between D hordein and malt extract was observed across seasons, treatments and cultivars that was indicative of a causal relationship between D hordein and malting quality. D hordein therefore offers an alternative measurement to total protein for the prediction of malting quality over a wide range of environmental conditions and cultivars. 相似文献

The amount of extract a malting barley cultivar can produce in the brewhouse will always be of crucial economic importance, and malts with high extract are desired. While the extract level of a particular cultivar is influenced, by genetics, environment and malting practice, it is anticipated that if quality grain is selected and optimally malted, extract levels will not vary much within samples of the same cultivar. Nevertheless, differences are observed in commercial practice, and the objective of this study is to determine which factors are most important in determining extract within a narrow population by use of statistical analysis. Four barley samples of the six-rowed malting cultivar, Tradition, were selected for the current study. All were of acceptable quality for malting. A randomized complete block design using barley sample, kernel size, germination days, and malting type as independent variables was carried out to give a wide variation in extract. Using analysis of variance and stepwise regression, results showed that soluble protein contributed the major variation (79%) in extract under different modification levels. However, under the same modification level, barley protein, 1000-kernel weight, and diastatic power explained the most (74.3%) variation in extract. The predicted extract equation takes the form: Extract=89.3−1.64Pr+0.16KW+0.019DP. 相似文献

综述了近年来有关大麦醇溶蛋白和麦芽品质之间关系的研究进展,分析了醇溶蛋白电泳条带模型与麦芽品质之间的关系。多数研究结果表明,二者之间没有关系,但是采用聚类分析发现,醇溶蛋白电泳模型以麦芽品质为依据进行分类是有效的;有关D醇溶蛋白与麦芽品质之间关系的研究结论也不一致,有研究认为D醇溶蛋白与麦芽浸出率之间呈显著负相关,并且这种关系不受品种和年份的影响。但有人利用Hor3缺失的近等基因系进行的研究结果则并不支持这一观点。另据研究,由D醇溶蛋白和B醇溶蛋白组成的凝胶组分含量与麦芽品质呈负相关。 相似文献
