Influența inoculării cu rizobacterii și aplicării acidulului salicilic asupra conținutului de peroxid de hidrogen și apă la soia (Glycine max. L) în condiţii de secetă
Get PDFRhizobacteria and salicylic acid (SA) have an important role in the promotion plant growth and enhancement of crops resilience to abiotic stresses. The aim of the study was to evaluate the effect of rhizobacteria (Bradyrhizobium japonicum) inoculation alone and in combination with salicylic acid on soybean (Glycine max L.) plants under moderate drought stress condition. Therefore, a pot culture experiment was conducted to test whether SA application at concentration of 0.5 mM through foliar spray could protect the soybean cultivar Horboveanca to short drought stress based on growth and alterations in hydrogen peroxide and relative water contents (RWC). The control treatment received 70% water holding capacity (WHC) of soil, whereas moderate drought stress corresponded to 35% WHC. Results showed that water deficit decreased RWC and increased hydrogen peroxide contents in leaves. The efficiency of Bradyrhizobium japonicum in the presence of salicylic acid was higher compare to plants treated with rhizobacteria alone. Thus, experimental findings demonstrated that integrated use of rhizobacteria and SA alleviates the adverse effects of water deficit on growth and contributed to drought tolerance of soybean through increased relative water contents and decreasing accumulation of reactive oxygen species in plant tissues

Get PDFUnfavourable trends have been identified in the evolution of climate factors (temperatures,
precipitation, etc.) over the past years, with a direct impact on the vegetative and productive potential of the
vine. This calls for a reassessment of climate resources and the adaptation of cultivation technologies to the new
conditions. Our paper analyses the climate data recorded between 1991 and 2020 for the Iaşi vineyard
ecosystem, which allowed for the calculation of a series of bioclimatic indices and coefficients, deviations from
the multiannual average values, soil moisture dynamics, and their influence on development of vegetation
phenophases and grape production. The increasing tendency of the average annual temperature and the
decreasing amounts of precipitation registered point to a marked warming of the vineyard climate, especially
after 2000. The high values of temperatures, corroborated with the soil water deficit, determined an
intensification of the atmospheric and pedological drought, a shift in vegetation phenophases, shortened
development periods and a forced ripening of grapes, with a negative impact on yields, which fluctuated from
one year to another. The analysis of the ecoclimate conditions over the past 30 years has highlighted an
alternation of periods, a colder and wetter one between 1991 and 2006, and a warmer and dried one between
2007 and 2020

Get PDFEurope's future depends on a healthy planet. Urban green spaces play a key role in improving the liveability of our towns. Current climate and environmental challenges require an urgent and ambitious response. Climate change is affecting our society in many ways. Rapid, and widespread reduction of greenhouse gas emissions and achieving a net level of greenhouse gas emissions CO2 equal to zero have the potential to limit climate change and its effects. That is why, lately, the world is fighting in various forms for the creation of new green spaces, especially in the most crowded urban areas. This paper aims to present a review regarding the green walls used to reduce the buildings energy consumption, to increase the phytoremediation of air pollutants, to increase the biodiversity and to contribute to life quality in the cities by their recreations and aesthetic functions
Research on the technical efficiency of anti-erosion works in the Izvoru Berheciului hydro-amelioration system
No full textThis paper presents the evolution after 1990 as well as the current state of some measures and anti-erosion works related
to the agricultural land within the hydro-improvement system of Izvoru Berheciului. The surface corresponding to the
hydroameliorating system Izvoru Berheciului is about 600 km2 and has over 75% sloped fields that occupy the
hydrographic basins of Drobotfor and Berheci. The high intensity of the erosion process by water in this area required
the execution of several different anti-erosion works in the above-mentioned hydrographic watershed, which
considerably slowed the soil degradation, the inundation and the clogging of the depression zones as well as the
deterioration of the environment. The best technical efficiency among the management systems was in the forestry
works and the anti-erosion hydrotechnical works. The works on slopes for the prevention and control of surface erosion
were mostly destroyed by the impact of the application of Law 18. The data obtained highlight the need to revive antierosion activities for the conservation of soil production capacity on slopes and the efficient use of land in the reference

Yield and bulb quality of storage onion cultivars as affected by farming system and nitrogen dose
No full textThe need of sustainable management system is connected both to environmental safeguarding and to the
increasing consumers’ demand for safety and premium-quality food. A research was carried out to assess the
interactions between 2 farming systems (organic, conventional), 4 nitrogen doses (100, 133, 166.5, 200 kg•ha 1
N) and 11 cultivars on yield, quality, antioxidants, elemental composition and heavy metals content of storage
onion bulbs. The bulb yield of six out of eleven cultivars was significantly greater in the conventional farming
than in the organic one, with Ramata di Montoro and Rossa di Tropea showing the best performances, even in
terms of plant dry weight, under both farming systems; Tosca reached the highest leaf area index. The conventional
farming system also led to higher bulb yield, dry weight, nitrate content and ascorbic acid compared to
the organic one for most cultivars, whereas quercetin was better affected by the organic management. The 166.5
and 200 kg•ha 1 N doses resulted in the highest yield as well as Leaf Area Index (LAI), and 200 kg•ha 1 N also
enhanced dry weight, nitrate content and ascorbic acid. The 100 kg•ha 1 N supply elicited the highest bulb
storability, whereas 166.5 kg•ha 1 N led to the highest bulb dry matter, soluble solids, total sugars, macroelements
and most microelements. The 133 kg•ha 1 N dose resulted in the highest monosaccharides, titratable
acidity, quercetin, polyphenols, and Antioxidant Activity (AOA). The cultivar Ramata di Montoro showed the
highest values of soluble solids, total sugars, monosaccharides and pungency. The cultivar Rosies des Aries
displayed the lowest bulb storability, along with Rossa di Tropea, and the highest dry matter together with
Grenada, Tosca and Zolotnichek. Polanowska attained the highest levels of antioxidants, AOA and macroelements.
The highest bulb accumulation of microelements and heavy metals differed with the cultivar, though
Ramata di Montoro showed the lowest accumulation of most heavy metals. Based on the outcome of the present
research, the conventional farming system is recommendable in terms of yield, for the 55% of the storage onion
cultivars examined, whereas the organic management improves the overall bulb quality, and the 166.5 kg•ha 1
N represents the most effective dose for achieving the best compromise between yield and quality

No full textContaminarea fructelor și legumelor cu metale grele în Europa
Get PDFHeavy metals are natural compounds of the soil and due the human activities and some natural causes, their levels exceed the legislative threshold values in some agricultural soils, becoming harmful for human health and environment. At the level of the European Union there are laws which regulate the threshold values of heavy metals in agriculture soils and in fruits and vegetables. Unfortunately, in markets there are still plant products of whose heavy metals (or other contaminants) content exceeds the maximum allowable levels. Contamination of food crops with heavy metals is mainly due to the crops growth in polluted soils and the excessive use of plants protection products with heavy metals. Thus, their short- or long-term consumption can pose risk to human health. In this context, the purpose of this paper is to identify, based on published studies, the content of cadmium, lead, copper and zinc in fruits and vegetables grown in different parts of Europe or sold on the markets of European Community countries. According to the results of published studies, the fruits and vegetables grown in certain areas of Europe, including in some areas of Romania, may be harmful to human health, the cadmium, lead, copper and zinc levels exceeding the maximum permitted limits
