High Level

Rutabagas (Brassica napobrassica Mill.) harvested in October and November contained a high level of sugars, more than 51% of dry matter. Roots harvested in September contained less sugars than those harvested later. Sugar concentration increased as much as 10% of dry weight during storage. Rutabagas harvested when the sugar concentration of dry weight reached the maximum level were of good eating quality. The optimum harvest time to obtain high quality rutabagas varied from year to year depending on weather conditions.

The Ideal

Fodder beets (Beta vulgaris L.) are especially respected for their high feeding value and high netto-energy yield per hectare. The price per nutritive value is lowest as compared to other forages. Preservation of fodders beets demands thorough cleaning without damaging and regularly occurs as a whole in well closed piles. In addition, feeding them to the animals is labour demanding. These disadvantages enforce the research towards other preservation methods which may be able to valorise this valuable type of roughage. The preservation of fodder beets in silages using silo bags, either separately or in combination with maize was investigated. Fodder beets were harvested and ensilaged at the ideal moment of maize harvest (October) or fodder beets were harvested at the ideal moment for fodder beet harvest (November) and consequently ensilaged with previously ensilaged maize. Highest energy yields of the silages were recorded at optimal harvest time for fodder beets. Ensilaging fodder beets separately resulted in large energy losses due to effluent and dry matter losses. Using lab scale silage, possible solutions for these large losses were investigated. Addition of 10% maize did reduce the effluent losses but dry matter losses remained at a high level. Addition of 4,5 l propionic acid per ton beets reduced effluent and dry matter losses sufficiently. Ensilaging foliage was another point of interest. This appeared to result in a lowered energy yield at organic and dry matter basis, an increased amount of ashes and doubling of the iron (Fe) concentration

Abstract BackgroundManagement of primary aldosteronism (PA) has become a research hotspot in the field of endocrinology. To obtain reliable research evidence, it is necessary to establish a high-quality PA research database. MethodsThe establishment of PA research database involved two steps. Firstly, patients with confirmation of PA diagnosis between 1 Jan 2009 to 31 Aug 2019 at West China Hospital were identified and data were extracted. Secondly, patients with confirmatory testing for PA will be enrolled into a prospective cohort. Data will be prospectively collected based on the case report forms since 1 Sep 2019. We evaluated the quality of research database through assessment of quality of key variables.ResultsTotally, 862 patients diagnosed as PA were identified, of which 507 patients who had positive confirmatory testing for PA were included into the retrospective database. Among 862 patients diagnosed as PA, the mean systolic blood pressure (SBP) was 156.1 mmHg, mean diastolic blood pressure (DBP) was 97.2 mmHg. Among included patients, the mean serum potassium level was 2.85 mmol/L, and the mean plasma aldosterone concentration (PAC) was 28.1 ng/dL. The characteristics patients with positive confirmatory testing for PA were similar. Validation of data extracting and linking showed the accuracy were 100%. Evaluation of missing data showed that the completeness of BMI (95.9%), SBP (99.4%) and DBP (99.4%) were high. ConclusionThrough integrating retrospective and prospective cohort of PA, a research database of PA with high quality and comprehensive data can be established. We anticipate that the research database will provide a high level of feasibility for management of PA in China.

Randomized Experimental Design

This study aimed to evaluate the quality of Hevea brasiliensis seedlings, a GT1 clone, produced in protected environments in a variety of substrates. The treatments consisted of 13 substrates composed of combinations of cattle manure, soil from a ravine, medium vermiculite, superfine vermiculite and washed fine sand and two environments: a greenhouse with 50% shade using aluminized screen and a plant nursery with 50% shade using a Sombrite® screen. There were no replications of the environments; therefore, each one was considered an experiment. For each environment, a completely randomized experimental design with five replications was used to evaluate the substrates. Subsequently, the average squares of the residuals of individual variance analyses of these treatments (substrates) were evaluated, and because they did not exceed an approximate ratio of 7:1, a combined analysis of experiments was performed with Sisvar software. Two hundred eighty days after sowing, the dry weight, plant height, stem diameter, diameter at five centimeters above soil and the seedling quality indices were evaluated. Results indicated that substrates with a low amount of manure and sand and a high amount of vermiculite (S9 and S13) produced rubber tree seedlings of high-quality. The environment with greater radiation availability was better for the development of high-quality rubber tree seedlings.

No significant studies have yet been reported in Central Europe on the yield and quality of winter harvest pastures. The aim of the research was to collect information about the effect of pre-utilisation (June, July and August) and winter harvest date (November, December, January) on the quantity and quality of fodder from Festuca arundinacea stands. The dry matter, energy, ADF, ADL and ergosterol contents of the yield were examined and it was found that: 1. A shorter regeneration period between harvests resulted in lower dry matter levels, but also in a higher energy concentration and lower ergosterol concentration. 2. The yield and energy concentrations decreased, whereas the ADF, ADL and ergosterol concentrations increased as the winter progressed. 3. Fodder harvested in November produced the best results in terms of yield quantity and quality. The highest yield and energy values were thus achieved by harvesting in November, regardless of pre-utilisation. Despite the cold and the long period of snow cover, the energy values of samples harvested in December and January showed no significant decrease. The weather conditions were more important for fodder quantity and quality than the frequency or date of harvesting. Thus, under the continental climatic conditions in Hungary, extensive utilisation, until late November or early December, is recommended.

The objective was to compare the quality of beef from bulls reared in typical Irish indoor systems or in novel grass-based systems. Bulls were assigned to one of the following systems: (a) grass silage plus barley-based concentrate ad libitum (CON); (b) grass silage ad libitum plus 5 kg of concentrate (SC); (c) grazed grass without supplementation (G0); (d) grazed grass plus 0.5 kg of the dietary dry matter intake as concentrate (GC) for (100 days) until slaughter (14.99 months). Carcass characteristics and pH decline were recorded. Longissimus thoracis was collected for analytical and sensory analysis. Lower carcass weight, conformation and fatness scores were found for grazing compared to CON and SC groups. CON bulls had highest intramuscular fat and lighter meat colour compared with grazing bulls. The SC meat (14 days aged) was rated higher for tenderness, texture, flavour and acceptability compared with grazing groups. CON saturated and monounsaturated fatty acid (FA) concentration was highest, conversely, omega-3 FA concentration was higher for GC compared with CON, while no differences were found in polyunsaturated FA. In conclusion, while market fatness specification was not reached by grazed grass treatments, beef eating quality was not detrimentally affected and nutritional quality was improved.

Our objectives were to quantify the growth and quality of herbaceous annuals grown in different types of bioplastic-based biocontainers in commercial greenhouses and quantify producer interest in using these types of biocontainers in their production systems. Seedlings of ‘Serena White’ angelonia (Angelonia angustifolia) and ‘Maverick Red’ zonal geranium (Pelargonium ×hortorum) that had been transplanted into nine different (4.5-inch diameter) container types [eight bioplastic-based biocontainers and a petroleum-based plastic (PP) (control)] were grown at six commercial greenhouses in the upper midwestern United States. Plants were grown alongside other bedding annuals in each commercial greenhouse, and producers employed their standard crop culture practices. Data were collected to characterize growth when most plants were flowering. Questionnaires to quantify producer perceptions and interest in using bioplastic-based biocontainers, interest in different container attributes, and satisfaction were administered at select times during the experiment. Container type interacted with greenhouse to affect angelonia growth index (GI) and shoot dry weight (SDW), as well as shoot, root, and container ratings. Container type or greenhouse affected geranium GI and shoot rating, and their interaction affected SDW, and root and container ratings. These results indicate that commercial producers can grow herbaceous annuals in a range of bioplastic-based biocontainers with few or no changes to their crop culture practices.

AbstractThe pea aphid, Acyrthosiphon pisum (Harris), affected yield by significantly reducing the mean height of aphid-susceptible Grimm alfalfa in a greenhouse experiment by 45%, the height of the longest stem by 35%, the green weight by 38%, the dry weight by 44%, and the fiber by 13%. There was limited change in quality of alfalfa. The percentages of protein, fat, total sugar, reducing sugar, dry matter, and nitrogen-free extract were not significantly different in the infested and non-infested alfalfa. Potassium was significantly lower in the infested plants but they contained more calcium, magnesium, and phosphorus. With the exception of isoleucine the amino acid composition was similar in the infested and non-infested alfalfa.

Research Findings

The aim of the study was to assess how the harvesting and ensilage technology influenced the quality of maize straw silages. The research findings showed that it was best to make maize straw silage in a flexible silo, whereas it was least favourable to make it in a film-covered field prism. The choice of the adequate ensilage method results in a high quality silage even if there is high content of dry matter in maize straw.

ABSTRACT Vernonanthura discolor is a native species with potential for reclamation of degraded lands, and the manufacture of wood panels. This study has aimed to evaluate the process of maturation and germination of Vernonanthura discolor seeds, determining the harvest time, and conducting the germination test. A periodic monitoring of the reproductive development of sources of Vernonanthura discolor was conducted, located in the municipality of Bocaiúva do Sul, PR, Brazil; and starting from the anthesis, weekly collections of seeds were performed to evaluate the percentage of dry matter, germinating power, and vigor, in order to identify the physiological maturity of the seeds. In the germination test, two combinations of four temperatures (20, 30, 20-30 and 30 °C), and two light regimes were tested, seeking to define the best methodology and evaluation dates of the test. It was concluded that the seeds physiological maturity Vernonanthura discolor reached 45 days after the anthesis, when the maximum values of dry weight, germination and vigor are achieved. Germination test may be conducted on blotting paper at 20 or 25 °C with a supply of light, or at 25 °C in the dark, the first count being on the 13th and the last one on the 29th day after seeding.

Compositional Changes

Six sweetpotato cultivars were evaluated for changes in individual sugar concentration, dry weight, and alcohol insoluble solids (AIS) during growth and development. Measurements were taken at weekly intervals from 7 to 21 weeks after transplanting. Sucrose, the major sugar during all stages of development, generally increased in concentration throughout development for `Heart-o-gold', `Travis', and `Jewel', but peaked at 17 weeks for `Beauregard' and `Whitestar'. The high-dry matter white flesh cultivars of `Rojo Blanco' and `Whitestar' contained the lowest sucrose concentration. The monosaccharides glucose and fructose generally decreased in concentration up to 17 weeks in 4 of 6 cultivars, followed by an increase from 17 to 21 weeks in all cultivars. Glucose concentration was marginally greater than fructose at all stages of development in each cultivar. Little or no increase in total sugar concentration occurred during development in `Whitestar' and `Rojo Blanco'. A substantial increase in total sugars occurred during development with `Jewel', `Beauregard', `Heart-o-gold' and `Travis'. Cultivars differed widely in their individual sugar concentrations during development. Percent dry matter increased in all cultivars from 7 to 14 weeks. Dry matter and AIS decreased during the later stages of development.
