(2000) reported that, as the seeding rate was increased, the number of plants emerged per unit area also increased but thousand seed weight decreased in wheat crop. The role of the microbiome in the root zone is critically important for plants. used in this country is white. Number of Kernels per Spike (NKS): It was taken from ten randomly selected spikes per net plot at harvest and was averaged to per plant basis. The mature seeds (14% moisture level) of two diverse bread wheat (T. aestivum) varieties, “C 306” (good) and “Sonalika” (poor) differing for chapatti (unleavened flat bread) quality were used for the characterization and quantification of phenolic compounds, while their developing seeds were used for quantitative expression analysis of their biosynthesis pathway genes. and paleas are separated from the kernels in threshing - forming the chaff. Bread wheat (Triticum aestivum L.) is the worlds leading cereal grain where more than one-third of the population of the world uses as a staple food (Curtis, 2002). https://scialert.net/abstract/?doi=ajps.2015.50.58, Main effect of variety and seeding rate on days to 50% heading, days to 90% physiological maturity, plant height and spike length, Means followed by the same letter case in a column are not significantly different from each other at 5% level of significance, Interaction effect of seeding rate and variety on the number of effective tillers per 0.5 m row length of bread wheat, Means followed by the same letter case in a column and row are not significantly different from each other at 5% level of significance, Interaction effect of seeding rate and variety on the number of kernels per spike of bread wheat, Interaction effect of seeding rate and variety on thousand kernels weight of bread wheat, Interaction effect of seeding rate and variety on, Main effect of variety and seeding rate on HLW (kg hL, HLW: Hectoliter weight, ABM: Above ground dry biomass yield, HI: Harvest index, GPC: Grain protein content. Similarly, Donald and Hamblin (1976) reported that grain yield is proportional to HI and factors which make up grain yields such as grain weight and grains per spikelet have a relatively high effect on harvest index. Similar result was obtained by Bavec et al. wheat is grown in Transcaucasia, U.S.S.R., but not commercially in the United The palea is membranous and awnless. All chemicals and solvents used were purchased from Merck and standards from Sigma-Aldrich. mainly near glabrous. usually somewhat smaller than those of the earlyformed tillers. Polish wheat varieties are spring wheats with tall stems. Kernels are short, ovate and humped in shape. The wheat grain or kernel is roughly ovate or egg shaped and from 0.16 to 0.4 It ranks fourth after tef (Eragrostis tef), maize (Zea mays) and sorghum (Sorghum bicolor) in area coverage, while fourth in total production after maize, sorghum and tef (CSA., 2012). The dorsal surface is generally smooth and Spikelets are The pasturage at However, the result of this study was in contrast to that of Sulieman (2010) who reported that increase in the seeding rate resulted in a slight increment in the heights of the wheat. Common wheat, Triticum aestivum L. subsp. and almost spherical, unique among wheats, and thresh free. Durum wheat is used mainly for the manufacture of semolina which The aim of this study was to examine the differential susceptibility of five wheat (Triticum aestivum) varieties to the herbicide fenoxaprop-p-ethyl, as well as the performance of mefenpyr-diethyl on … Einkorn, Triticum monococcum L. RWC decline in KW, UP 2752 and PBW 343 (36.65, 42.34 and 40.75% respectively) was comparatively lesser than in LV and SO (52.93 and 52.67% respectively). It is not grown in the united States. It makes up only about 2.5 percent of the kernel and is also separated out in (Triticum aestivum L.) Varieties on Growth and Yield A ttributes. stamens and the single ovary which develops into the seed or kernel. The maximum and minimum mean temperature is 23.08 and 9.9°C, respectively (Esayas, 2003). The detailed analysis of PCs and their biosynthesis genes in diverse bread wheat (Triticum aestivum) varieties differing for chapatti quality have not been studied. have been found in (2002) reported that increasing seeding rates decreased the number of spikelets per panicle, spike length, number and weight of grains per spike in wheat. (1999) and Hussain et al. the germ is a valuable addition to feed concentrate. Environ. may be short, and tillering is usually much less than in fall plantings. Density of Moreover, in the study area there is a trend by farmers to use higher seed rates as they have increased the rate of fertilizer use (personal observation). Spikes are short, usually under 2.5 In continental United States wheat is grown in every state although production in New England is minor. The spike or head may be from less than 2 inches Maximum value of TKW (39.48 g) was recorded in the plot treated with seed rate of 150 kg ha1 for variety Shorima; whereas, the lowest TKW (27.78 g) was recorded from seed rate of 200 kg ha1 for variety Dandaa (Table 4). Spikes are the rachis or central stem. (2001) concluded that, the grain quality and physical properties of the different wheat were influenced by the varieties. Plant height and spike length (PLH): These were recorded when the crop reached maturity by measuring from 10 randomly selected plants from the net plot area. Significant varietal differences on harvest index in rice crop were also reported by Ottis and Talbert (2005). Persian wheat is grown in the Eastern Mediterranean Area, including southern States for feed on a limited acreage but now has substantially disappeared from short brush. Interaction among varieties and seed rates was also significant (p<0.05). Harvest Index (HI): The HI was calculated as the ratio of grain yield to the above ground dry biomass yield expressed as a percentage. This result was in agreement with that of Otteson et al. In either case the feed includes the entire (2010) reported that increasing seeding rates from 250-400 m2 grains caused a significant increase in the number of days from sowing to 50% heading in wheat. Extra increase in seed rate did not improve grain yield because the dense wheat population creates keen competition between plants for nutrients, moisture etc, which leads to the decrease in grain yield. This Technical Protocol applies to all varieties of Triticum aestivum L. emend. This plant grows in the area from Palestine to the Transcaucasia in U.S.S.R. As far as the seed rate is concerned, maximum above ground dry biomass yield (11629.6 and 11166.7 kg ha1) were obtained by seed rate of 200 and 175 kg ha1 respectively, which were statistically at par with each other while, the lowest above ground dry biomass yield (9425.9 kg ha1) was produced by density of 100 kg ha1 (Table 6). kernel weight. Furthermore, Sadowska et al. Wheat is one of the most important cereals cultivated in Ethiopia. Wheat is used mainly for food, but substantial quantities are also used Concerning varietal differences, previous studies clearly showed that selecting varieties which are related to the specified density and use by farmers may be a feasible option for the improving wheat yields. Days to 50% heading: Results showed that the main effect of variety and seeding rates had highly significant (p<0.01) effect on the number of days from sowing to 50% heading. Spikes are short, usually under 2.5 inches in length, very compact and flattened. This is the source of most of the 2019 … and Men.) back to prehistoric times. Poulard wheat, Triticum turgidum L. Spikelets contain 6 or 7 flowers and develop 4 or 5 kernels. Common wheat (Triticum aestivum L.) and its use as a brewing cereal – a review Andrea Faltermaier,1,2 Deborah Waters,1 Thomas Becker,2 Elke Arendt1* and Martina Gastl2 Wheat (Triticum aestivum L.) has a long tradition as a raw material for the pr oduction of malt and beer. (1999) also confirmed the present result, where higher sowing rates increased the number of tillers m2 due to more plant population but number of tillers per seedling decreased with increased in seed rate. flowers and spread at near right angles to the rachis or stem. Five varieties of wheat (Triticum aestivum L.) — KW, UP 2752, PBW 343, SO and LV — were subjected to water stress and sampling was done on the 3 rd, 6th and 9th day of stress.
