Root and Shoot Traits of Spring Wheat Cultivars with Wild-Type and Semi-Dwarf Rht Alleles at Early and Late Growth Stages
2021
Hayati Akman | Philip Bruckner
Roots play an important role in improving crop yield by affecting the amount of water uptake and nutrient acquisition. The objective of this study was to characterize variability in root and above-ground characteristics among three diverse semi-dwarf spring wheat cultivars, ‘Vida’, ‘Oneal’ and ‘Duclair’ and a wild-type cultivar, ‘Scholar’ at early and late growth stages in a greenhouse. Plants were grown in 45-cm long tree pots in a greenhouse under optimal growth conditions. As soil-less media, a mixture of peat (70%) and perlite (30%) was used. Plants were harvested at tillering (GS25-26) with 5-6 tillers, booting (GS43-45), and maturity (GS92). Root and shoot traits indicated significant variability among wild-type and semi-dwarf spring wheat cultivars at those growth stages. The study results showed that root mass per plant at tillering, booting, and maturity ranged from 0.10 to 0.14 g, 0.47 to 0.9 g, and 0.55 to 0.85 g, respectively, while shoot mass per plant varied from 1.7 to 2.5 g, 6.5 to 10.7 g, and 21.2 to 24.5 g, respectively. From booting to maturity, root mass was relatively constant, however, shoot mass increased considerably. Moreover, the average root mass of semi-dwarf spring wheat cultivars was 37% lower at booting and 30% lower at maturity compared to the wild-type cultivar, even though there was no significant variation among the cultivars at the early growth stage. Based on the results of the variability identified in this research, wild-type cultivar, Scholar can be evaluated for the improvement of genotypes with superior root system in breeding programs.

Aysun Eraslan Sür | Erçin Oksal
Turkey is known as a top producer and exporter of apricots, both fresh and dried. More than half of Turkey's apricot production is provided by Malatya province. There are many pests and diseases affecting apricots in addition to climatic factors such as frost and hail. Partial shoot drying and sudden drying in apricot orchards have increased in recent years. In this study, it was aimed to determine the chemical control possibilities of Neoscytalidium dimidiatum (Penz.) Crous &Slippers, which is one of the fungal agents that cause partial branch drying and sudden drying in apricot orchards in Malatya province by in vitro studies. For this purpose, Kale 4-C isolate of N. dimidiatum collected from Malatya in a previous study was used. Mycelial growth of N. dimidiatum Kale 4-C isolate in PDA were observed in 0 (control), 0.01, 0.03, 0.1, 1, 3, 10, 30 ve 100 μg/mL concentrations of Azoxystrobin 250g/L, Trifloxystrobin %50, Tebuconazole %25, Floupyram 200 g/L+Tebuconazole 200 g/L, Cyprodinil+Fludioxonil %37.5+25, %70 Thiophanate-Methyl and 400 g/L Phosphorous acide fungicides applications. As a result of the study, Floupyram 200g/L+Tebuconazole 200g/L ve Cyprodinil+Fludioxonil %37.5+25 fungicides effectively inhibited the mycelial growth of the fungus.

Ambient storage stability is one of the major constrains amidst drudges of homemade soymilk due to absence of stabilizer there by restricting the consumption to the production areas. Homemade stabilizers and stabilization becomes the only available option. Soymilk prepared from 12 h steeped and 72 h sprouted soybeans was subdivided and each batch stabilized with 0.5%, 1%, 2% and 3% levels of orange flesh sweet potato starches (OFSPS). Functional properties of the starches and proximate, vitamins, minerals, anti-nutrient, physicochemical, and sensory properties of stabilized soymilk samples were assessed with standard analytical methods. With increase in fortification levels, there were significant improvement in ash (0.84 to 0.88%), protein (4.14 to 4.24%), fibre (0.31 to 0.39%), fat (3.75 to 4.19%), carbohydrate (4.54 to 5.55%), vitamins B1 (0.29 to 0.4 mg/100g), B2 (0.10 to 0.14 mg/100g), B3 (1.03 to 1.13 mg/100g), C (0.86 to 1.09 mg/100g) and pro-vitamin A (5.75 to 6.14 µg/100g). Also improved are calcium (26.81 to 28.55 mg/100g), potassium (31.54 to 32.95 mg/100g), magnesium (44.40 to 46.82 mg/100g), sodium (32.73 to 33.43 mg/100g), iron (2.82 to 3.71 mg/100g), saponin (0.028 to 0.035 mg/100g), tannin (0.041 to 0.048 mg/100g), flavonoid (0.031 to 0.034 mg/100g), alkaloid (0.025 to 0.034 mg/100g), phenol (0.25 to 0.34 mg/100g), viscosity (4.89 to 5.60 mg/100g) and specific gravity (1.02 to 1.04 mg/100g). There were decrease in moisture (86.39 to 84.86%), pH (5.75 to 5.45), visible coagulation time (VCT) (28 to 14 d), foam stability (0.51 to 0.00) and general acceptability (6.84 to 4.84). Functional properties of the OFSPS flour were reasonably high. Despite the anti-nutrient increase, all the soymilk samples in this study were safe for human consumption and moderately accepted at maximum stabilization level of 1%.

This study was carried out to determine the effects of lactic acid bacteria+ enzyme (LAB+E) inoculants on the fermentation characteristics and feed values of silages prepared from alfalfa harvested at three maturity stages. Alfalfa was harvested at the early, middle and late flowering stages. Sil-All (Alltech, UK) were used as LAB+E inoculants. Inoculants were applied to the silages at the rates of 1×105, 5×105 and 1×106 cfu/g levels in 1 liter capacity plastic bags. The bags were stored at 20±2°C under the laboratory conditions. Three bags from each group were sampled for chemical and microbiological analyses on the 45th day after ensiling. The results showed that LAB+E inoculants reduced pH values and ammonia-nitrogen content, whereas increased lactic acid contents and lactobacillus count of alfalfa silages. High doses LAB+E inoculant decreased neutral detergent fiber and acid detergent fiber content, increased in vitro organic matter digestibility and metabolic energy of alfalfa silages. It has been demonstrated that the most effective application dose of LAB+E inoculant to improve fermentation and feed value of alfalfa silage was 1×106 cfu/g, but 1x105 and 5×105 cfu/g level can also be considered as effective dose.

This study evaluated age-related changes in the gross morphology and morphometry of the testis and epididymis of the African Greater Cane Rat (AGCR). Twenty pathogen-free cane rats used for this study were randomly divided into 4 groups; Group I - prepubertal (≤4 months), Group II - pubertal (>4≤12 months), Group III - adult (>12≤30 months), and Group IV - aged (>30 months) of 5 animals each. On day 8th of acclimatization, testis and epididymis were harvested from sedated cane rat, described grossly and standard morphometric parameters (length, width, circumference, weight, and relative weight) determined. Gross morphological observations in the testes of all the different age categories showed similar characteristically cream to milky-white coloration and ellipsoidal shape. The epididymis in the different AGCR group uniquely presents the same inverted S-shaped outline, loose attachment to the testis, and less distinct division into caput, corpus, and cauda segments. Testicular and epididymal morphometric parameters were significantly reduced in the prepubertal cane rat relative to other groups. The parameters consistently displayed an age-dependent increment with the advancing age of the animal. In conclusion, this study has shown that both testicular and epididymal gross morphometrics increase with age advancement and perhaps might be linked to the varying functional reproductive status of the different age groups of the African greater cane rat.

Phosphorus (P) fertilizers contain cadmium (Cd) as a contaminant at levels varying from trace amounts to high levels and therefore, can be a major source of Cd to agricultural systems. This study was designed to assess the impact on application of Eppawala rock phosphate (ERP) and triple super phosphate (TSP) as P fertilizers and different soil amendments on P and Cd uptake in maize (Zea mays L.). The field trial was carried out at Field Crop Research and Development Institute at Mahailluppallama, Sri Lanka. A randomized complete block design was employed with three replicates as ERP and TSP separately applied with arbuscular mycorrhizal fungi (AMF) and three types of amendments (biochar, compost and dolomite) and the control without adding P fertilizers. Phosphorus content and Cd content of soil, maize roots and seeds were quantified. Results revealed that available soil Cd and total accumulated root and seed Cd amounts were significantly higher in TSP added treatments with and without amendments compared with ERP added soil. Considering soil available P, root and seed P, there was no significant difference observed in different treatments of TSP and ERP added treatments. A similar phenomenon was also observed in growth and yield parameters with both fertilizers added and with the added amendments. There was no colonization of AMF in maize roots in TSP applied soil while 25-60% of colonization was recorded with ERP. Synthetic fertilizer (TSP) must have inhibited the AMF colonization and thereby increasing the Cd content in maize seeds. AMF colonization increased with comparatively low soil available P in ERP added treatments. The results revealed that TSP could be effectively substituted by ERP as a source of P for maize soils. The addition of AMF, compost and biochar further increased the effect.

Şeref Turhan | Aslı Kurnaz
Wheat is an important cereal product because of its nutritional value, economy, culture, and history. Einkorn (Triticum monococcum L.) assumed as the oldest wheat. Einkorn locally called “siyez” has recently become popular as a super grain with the thought of being very nutritious in Turkey. In this study, the contents of macrominerals (Na, Mg, Ca, and K) and microminerals (Cr, Cu, Fe, Mn and Zn) in twenty-one einkorn samples collected from different cultivation areas in Kastamonu were determined by using an inductively coupled plasma-optical emission spectrometry following microwave-assisted acid digestion. The results were compared with those analyzed in einkorn and other wheat types in the literature. Average concentrations of K, Ca, Mg, Na, Fe, Zn, Mn, Cr and Cu analyzed in einkorn samples were found as 3712, 1303, 656, 53, 167, 34, 29, 0,7 and 0,6 mg kg-1, respectively. The literature comparison revealed that the investigated einkorn samples were richer in terms of Ca and Fe contents compared to einkorn, emmer, spelt, buckwheat, and durum wheat samples grown in our country and different countries.

The present study was planned to determine the effect of flock age on hatching results and chick quality in Ross 308 broiler parents. For this purpose, the eggs of three different flock age (30, 47, and 59 weeks of age) were used. A total of 450 eggs (50 × 3 for each group), including 150 eggs from each age group, were placed in the incubator as a coincidence. The number of alive chicks after hatching was determined and these chicks were classified into three quality groups as low quality, high quality, and discarded chicks. Non-hatched eggs were broken in order to control the fertility and determine the embryonic deaths. At the end of the study, the effect of the flock age on fertility rate (%), hatchability (%) and chick quality was found to be significant. However, the effect of flock age on hatchablity of fertile eggs and early, mid, and late-period embryo deaths were found to be insignificant. It was found that eggs obtained from the young breeders were higher in terms of fertility rate and hatchability than eggs obtained from old breeders. The chicks obtained from young breeders' eggs were determined as 33.60% high quality, 48.10% low quality, and 18.30% discarded chicks. These rates were 32.70%, 43.40%, and 23.90% in chicks obtained from middle-aged breeders, respectively, 56.10%, 36.40%, and 7.50% in chicks obtained from the old breeders. As a result, it was determined that there was a decrease in the hatching results in parallel with the increase in breeding age, but the chick quality increased.

A field-based experiment was carried out in Rukum (East), Nepal, from February to June 2020, to assess the effect of different pre-sowing treatments on germination of Persian walnut. The experiment was carried out in a randomized complete block design with six treatments and four replications. The treatments included hot water treatment, chilling stratification only, cracking + Gibberellic acid (500ppm) followed by chilling stratification, cracking + Gibberellic acid (750ppm) followed by chilling stratification, Gibberellic acid (500ppm) + chilling stratification and Gibberellic acid (750ppm) + chilling stratification. The minimum days for germination (15.75 days) and highest germination (53.25%) were obtained when the combination of cracking with GA3 @ 750 ppm along with chilling stratification was done. The maximum shoot length (34.83 cm) was observed in the combination of cracking with GA3 @ 500 ppm followed by stratification but statistically similar shoot length (34.63 cm) was observed when cracking, application of GA3 @ 750 ppm followed by stratification was done. Cracking, treatment with GA3 @ 500 ppm followed by chilling stratification resulted in the highest shoot fresh weight (11.93 gm) and root fresh weight (10.77 gm) compared to the other treatments used. Thus, cracking along with treatment by GA3 @ 750 ppm followed by chilling stratification could be suggested to the walnut growers for better germination and a better morphological and physiological status of the rootstocks/seedlings.
