The Technological Process of Obtaining New Linen Dressings Did Not Cause the Loss of Their Wound-Healing Properties

Background: Linen dressings were invented a few years ago but are still being worked on. Methods: The obtained fabrics from the traditional variety of flax (Nike), two transgenic types of flax (M50 and B14) and the combination of these two flax fibers (M50 + B14) were tested in direct contact in cell cultures. Cell viability tests were performed, and the proliferation potential of cells on Balb3T3 and NHEK cell lines was checked using the Sulforhodamine-B (SRB) test. Moreover, the effect of new linen fabrics on apoptosis of THP-1 cells, as well as on the cell cycle of NHEK, HMCEV and THP-1, cells after 24 h of incubation was assessed. Results: All tested linen fabrics did not raise the number of necrotic cells. The tested fabrics caused a statistically significant decrease in the total protein content in skin cancer (except for 0.5 cm of Nike-type fabrics). The smallest cells in the apoptotic phase were in cultures treated with M50 fiber on an area of 0.5 cm. After 48 h of incubation of HEMVEC, NHEK and THP-1 cells with the tested fabrics, the growth of S-phase cells was noticed in all cases. At the same time, the greatest increase was observed with the use of B14 fabric. Necrosis is not statistically significant. Conclusions: All the obtained flax fibers in the form of flax dressings did not lose their wound-healing properties under the influence of the technological process. New dressings made of genetically modified flax are a chance to increase the effectiveness of treatment of difficult healing wounds.

Influence of different sowing density in two varieties of maize. Part II. Relation to agricultural morphological features

Summary In this paper, we investigate the effect of seeding density on several morphological features such as plant height, height of the production ears, ear length, ear diameter, leaf area, and LAI (leaf area index). Inference is based on a series of three-year two-factor experiments with two hybrid maize varieties – SY Cooky and Drim “stay-green” type – and 5 sowing densities: 6, 7, 8, 9 and 10 plants per m2. The “stay-green” maize variety had production cobs significantly higher on the plant, and had a thicker cob and a larger leaf assimilation area than the conventional variety. Increasing maize sowing density from 6 to 10 plants m−2 resulted in a linear decrease in cob length and diameter, while it increased the LAI. Significantly higher chlorophyll content, expressed in SPAD units, was found in the “stay-green” hybrid at the BBCH 67 stage in a wet (2012) and drier year (2014), compared with the traditional variety. This may indicate that such a variety is more tolerant to stress conditions.

Main Phenotypic and Biochemical Characteristics Recorded at the New ‘Andrada’ Tomato Variety Obtained at Vegetable Research and Development Station Buzău

The Breeding and Biodiversity Laboratory within the Vegetable Research and Development Station Buzău with 11 tomato varieties listed in the Official Catalogue of Cultivated Crops in Romania and a valuable resource of Solanum lycopersicum germplasm composed of over 2,000 genotypes, focused its research to obtain tomato varieties for precise use: fresh consumption and industrialization. Starting from a valuable traditional variety (‘Inimă de bou’ – ‘Ox Heart’), the aim was to obtain a new, improved variety of tomato for consumption of fresh fruits, with large, juicy fruits highly appreciated on local market. Research resulted in the approval and patenting of the ‘Andrada’ tomato variety with distinct genotypic and phenotypic characteristics.

THE AGRONOMIC CHARACTER AND POTENTIAL YIELD OF 17’S GENOTYPE OF MAIZE

Maize (Zea mays L.) is one of crops that source of carbohydrate than rice. The maize production needs to production goal. The problems is traditional variety haved low yield. This study aims to determine the agronomic character and potential yield of several hybrids maize.. The research method used was randomized completely block design was repeated 3 times. The treatment factor namely hybrid maize genotype. The data obtained were analyzed in theirs diversities by using variace at 5 % level, if there were significant difference, continued by using the least significant increase at 5% level to compared of variety tester. The results shows that hybrid maize genotypes, G2KPW-43, G2KPW-45, and G2KPW-48 haved superiorities in agronomic character and higher potential yield.Key words: genotypes, potential yield, maize

Salt stress induced accumulation of biomolecules in groundnut genotypes

Salinity is one of the environmental limiting factors in agricultural production. The aim of this study was to find out one of more salt tolerant groundnut genotypes through monitoring the growth and changes in biomolecules under salt stress condition. Purposively four groundnut genotypes, including a Traditional variety, Zhingabadam, Binachinabadam-1 and Dacca-1 were grown under three salinity levels viz. 0, 3 and 5 dSm-1. The experiment was laid out in two factorial completely randomized design with three replications. This experiment was done in soil based pot culture up to 40 days. Increasing salt concentration drastically reduced all the growth parameters, and increase proline and sugar content of leaf. Among the varieties Traditional variety, Zhingabadam and Dacca-1 had statistically similar shoot and root dry weight. The leaves of the Traditional variety contain the highest amount of proline of 14.52 and 36.24 mg/100g fresh leaves in 3 and 5 dS/m salinity, respectively which was 236 and 737 % higher than that of respective control. At EC of 3 and 5 dS/m, the variety Binachinabadam-1 was appeared to be susceptible, having an increase of 6 and 113% proline content over the respective control. Based on the shoot dry weight, root dry weight, proline content, total sugar, reducing sugar and relative water content, the Traditional variety was strongly recommended to be grown in the coastal salt affected soils. The Zhingabadam and Dacca-1 variety also could be recommended as they had comparable performance of the Traditional variety.

RESEARCH & DEVELOPMENT OF PUBLIC-PRIVATE SECTOR WITH REFERENCE TO PROTECTION OF PLANT VARIETIES & FARMER RIGHTS

The main aim of this paper is to investigate the role of public and private sectors in registering their plant variety under different categories as well as mapping the role of public, private and farmer’s right with reference to legal provisions. The graphical representation of data set of registered varieties (from 2009-2018) i.e. new, extant variety and farmer variety in a longitudinal way to analyze the participation of the public, private sector in registering the plant varieties. The finding of this study clearly indicates that during the initial year i.e. 2009-2012 not so many varieties got registered after that 2013-2018 specially in 2014 large varieties get registration in different categories. The finding gives a comparative viewpoint that initially in the year 2009 to 2012 public sector played a significant role in registration thereafter 2013-2018 private sector invest a lot specially in 2014 where large number of varieties register by farmers of Odisha with reference to their farmer’s right. This research gives a clear depiction to the private industries a positive trajectory of benefit of registering the variety of plant under the PPV & FR legislation. The Odisha case study enumerates the role of government and their public policies to encourage farmers to register their traditional variety and get benefit out of it
