In this study, the effect of different doses of gamma ray (200, 300, 400 and 500 Gy) applied on seeds of Tarm-92 two-row barley varieties on some agricultural properties were investigated. The research was conducted in 2016-2017 vegetation period under Isparta conditions. In M1 generation, normal and abnormal plants are harvested separately according to the spike and plant appearance at each dose and 9 different [200, 200 A, 300, 300 A, 400, 400 A, 400 A (plants with double spike formation and branching tendency in spike Ç.B.) 500 and 500 A gray] groups were formed. A total of 10 plots with control (no irradiation) were included in the M2 generation. Results showed that the effect of gamma ray application on the thousand grain weight, test weight, ratio of husk and protein content was significant statistically. While increasing the ratio of husk and protein content, gamma ray application significantly reduced the weight of a thousand grains and test weight. In this research, plant height, spike length, number of grain per spike and weight of grain per spike were investigated on a single plant. Discriminant analysis was done and distance between groups was determined. The rate of plants similar to control in examined characters in M2 generation is 400 Gy 7.83%, 200 Gy 10%, 300 Gy 19.60% and 500 Gy 22.22%. When the coefficients containing linear separation functions are examined, it is determined that the most effective feature is spike length.

Background: The urd bean variety MDU 1 has a duration of 70-75 days, bushy in nature and is susceptible to yellow mosaic virus. In order to develop a determinate type and improved batter quality, MDU 1 and VBN (Bg) 4 blackgram seeds were treated with different doses (100 Gy, 200 Gy, 300 Gy, 400 Gy and 500 Gy) of gamma rays. Methods: Uniform sized seeds treated with different mutagenic doses were raised in randomised block design which constitute M1 generation. Each plant was harvested individually and forwarded to M2 generation following plant to progeny row method. The determinate types were selected from M2 generation and forwarded to further generations. After attaining homozygosity in the advanced generation, the mutants were checked for its biochemical characters (Total solubule protein content analysed by kjeldahl method, albumin and globulin analysed by Lowery’s method, arabinose content analysed by Bial method. Result: The mutants ACM - 16 -011, ACM - 16 -015, ACM - 16 -018 were found to have an arabinose content of 8.28%, 8.98% and 8.14% respectively. All these mutants recorded more batter volume over the variety MDU 1. The albumin (%) and globulin (%) contents were also found at remarkably increased levels in the mutants. These mutants have the potential to develop a high quality variety of urd bean and therefore are very useful in breeding programme.

Influence of CULTAN system (controlled uptake long term ammonium nutrition) on the nitrogen uptake by spring barley (Hordeum vulgare L.) was observed at 5-year small-plot field experiments under conditions of the Czech Republic (central Europe). Nitrogen uptake by CULTAN-fertilized plants was more even during vegetation period probably due to delayed term of fertilizer application. Nitrogen concentration in the aboveground biomass at BBCH 51 and in straw had no effect on grain yield. Post-heading nitrogen uptake as well as contribution of nitrogen translocation to total nitrogen in grain did not differ among both nitrogen fertilization treatments. Increase in grain size of spring barley by the CULTAN system can be explained by tendency to lower number of ears per area rather than by prolonged nitrogen uptake from soil. Lower protein content in grain of CULTAN-fertilized spring barley can be caused by increase in grain retained on a 2.5 mm sieve and also decrease in total nitrogen concentration in above-ground biomass at BBCH 51. No significant effect of CULTAN treatment on nitrogen use efficiency and nitrogen uptake efficiency was recorded. Significantly higher nitrogen utilization efficiency at CULTAN treatment could be explained by lower grain protein content compared to conventional treatment.

Although leaf spotting diseases have been reported to have a negative effect on grain yield and seed characteristics of wheat (Triticum spp.), the magnitude of such effects on wheat grown on dryland in southern Saskatchewan is not known. A fungicide experiment was conducted at Swift Current (Brown soil) and Indian Head (Black soil) from 1997 to 1999 to determine the effect of leaf spotting diseases on yield and seed traits of wheat. Two fungicides, Folicur 3.6F and Bravo 500, were applied at different growth stages on three common wheat (Triticum aestivum L.) and three durum wheat (T. turgidum L. var durum) genotypes. Fungicide treatments generally did not affect yield, kernel weight, test weight or grain protein concentration, and these effects were relatively consistent among genotypes. Folicur applied at head emergence in 1997 and at flag leaf emergence and/or head emergence in 1998 increased yield at Indian Head (P < 0.05). Fungicides applied at and before flag leaf emergence tended to increase kernel weight. Grain protein concentration increased only in treatments of Bravo applications at Indian Head in 1998. These results suggested that under the dryland environment and management in southern Saskatchewan leaf spotting diseases generally have a small effect on yield, kernel weight, test weight and protein concentration.

SUMMARYVarietal and environmental factors which influence test weight were investigated in a field trial with ten varieties of winter wheat and two rates of nitrogen fertilizer. Varietal differences in test weight were correlated positively with the protein content of the grain and inversely with grain yield but they were not related to 1000-grain weight or to flour yield. Variation in test weight associated with varietal and environmental effects in protein content was due to differences in the density of the grain, as measured by displacement of xylene. Separation into density grades within a sample by a flotation method showed a similar relationship with protein content. There were also varietal differences in packing efficiency of the grain. In the case of Maris Huntsman a poor packing efficiency was considered to stem from morphological features of the floret and developing grain which lead to characteristic transverse folds in the ventral surface of the mature grain. For wheat grown in the United Kingdom, test weight may provide a useful guide to flour yield for samples of one variety but it is likely to be misleading for comparisons between varieties.

AbstractCanadian Western Hard Red Spring (CWRS) wheat is recognized as premium quality wheat, ideal for breadmaking due to its superior milling qualities, baking characteristics and protein content. Organic wheat production is becoming more prevalent in Canada, due to increasing consumer demand for organic wheat products. Differences may exist in the baking and milling quality of wheat grown under conventional and organic management, a result of the dissimilarity between organic and conventional soil and crop management practices. Five CWRS cultivars released from 1885 to 1997 were grown under conventional and organic management and were assessed for their breadmaking potential. Several traits were investigated, including test weight, protein content, flour yield, kernel hardness and several mixograph parameters. Test weight was higher under conventional management, while no differences in protein content were observed between organic and conventionally grown wheat. Higher sodium dodecyl sulfate sedimentation (SDSS) volume, a reflection of gluten strength, was observed under conventional management, while there was a trend towards higher dough strength under organic management. Cultivars differed in grain protein, flour yield, kernel hardness and mixograph parameters, with Park and McKenzie superior to the others, particularly Red Fife, a much older cultivar. Management×cultivar interaction effects suggest that cultivars exhibit somewhat different baking characteristics when grown in the two management systems. There was no evidence that older cultivars (developed prior to the widespread use of pesticides and fertilizers) are better suited, in terms of breadmaking quality, for organic production.

Mineralizable N

In an 8-yr experiment on an irrigated Dark Brown Chernozemic soil, four rates of N (0, 34, 67 and 101 kg ha−1), applied annually with 45 t ha−1 of manure containing softwood shavings (avg. of 46% dry wt) produced a linear yield response (from 3.5 with the check to 4.3 t ha−1 at the highest rate) of barley grain (Hordeum vulgare L. 'Galt'). There were large differences in yields among years, which could be attributed to weather factors, but there was no significant N × year response. Protein content increased linearly (from 11.2 to 13.5%), and both kernel weights and "test weights" (kg hL−1) decreased slightly but significantly with N applications. There was a pronounced "residual" effect of N rates on both grain yield (from 3.8 to 6.3 t ha−1) and protein content (from 10 to 13%) in the first year after applications of manure and N fertilizer ceased. These effects decreased rapidly and had practically disappeared by the end of the 3rd yr, although yields of all treatments remained high (about 5 t ha−1). Organic matter and N contents of the soil were increased by 70 and 41%, respectively, from the cumulative applications of shavings manure. It is concluded that application of manure containing large quantities of softwood shavings has a negligible effect on the N fertilizer requirements of the crop being grown. Beneficial residual effects of N fertilizer applied with the manure may result because of buildup of NO3-N throughout the soil profile, and likely also because of N release from readily mineralized organic compounds or microbial biomass. However, this effect was not reflected in soil tests for readily mineralizable N by NO3 incubation or KCl digestion methods and the effects were practically dissipated after 3 yr. The recovery of applied N fertilizer by the crops was high at all rates (61–79%), and essentially all of the N applied (fertilizer + manure) was accounted for by crop removal + increased soil N.

ABSTRACT Uterine weight, RNA, DNA, protein content, in-vitro rate of protein synthesis, cytosol oestrogen and progesterone receptors were examined after administration of oestradiol to ovariectomized animals and on days 0, 5, 9 and 13 of the non-pregnant cycle and day 13 of pregnancy. In ovariectomized animals, oestradiol increased uterine weight, RNA: DNA and protein: DNA ratios and the concentration of cytosol receptors for oestradiol and progesterone. During the oestrous cycle there was a linear increase in uterine weight and a significant effect of the corpus luteum on the weight of the ipsilateral uterus. Changes in RNA, DNA and protein content between days 0 and 5 were not observed, but between days 5 and 13 RNA: DNA and protein: DNA ratios increased and the DNA: tissue weight ratio decreased. Thus, cellular hypertrophy and/or increased metabolic activity rather than hyperplasia occur over this period, which is coincident with the known rise in plasma progesterone levels. The rate of in-vitro protein synthesis (per unit tissue protein) during the non-pregnant cycle was greatest at day 0. These changes in uterine metabolic activity were associated with alterations in cytosol receptor concentrations for both steroids. Cytosol progesterone receptor concentrations were highest at day 0 after which they declined to a minimum at day 13. Cytosol oestradiol receptor concentrations, however, rose between days 0 and 5 and then declined. Although lutectomy on day 8 of the cycle does not interfere with the development of a histologically normal luteal phase, high peripheral progesterone levels which occur after day 8 in intact animals are associated with major increases in uterine metabolic activity. The unilateral effect of the corpus luteum on uterine weight was associated with a decrease in DNA: g tissue ratio and an increase in rate of in-vitro protein synthesis indicating hypertrophy and/or extracellular accumulation of secreted material as well as enhanced metabolic activity. There was a significant effect of pregnancy on uterine weight at day 13 and this was associated with an increase in DNA content of both uteri. There was a unilateral effect of pregnancy on RNA: DNA ratio and in-vitro rate of protein synthesis, but not on uterine weight. J. Endocr. (1986) 108, 201–210
