Soybeans are species of legume that has become one of the most widely consumed food in the world, because they are easy to cultivate and very beneficial for human health. The quality of the cultivated plants, including the content of toxic heavy metals depends to a large extent on the contaminants present in the soils in which they are grown and the method of fertilization. Through this research we aim to highlight the degree of accumulation of cadmium, chromium, cobalt, copper, nickel, lead and zinc in relation with the cultivated soybean genotype and fertilization. Three soy varieties (Cristina, Felix and Onix) were cultivated in an experimental field located at Cojocna Experimental Didactic Center of the University of Agricultural Sciences and Veterinary Medicine of ClujNapoca. The above-mentioned heavy metals were determined from the harvested mature soybean seeds using inductively coupled plasma-optical emission spectrometry, using an Avio 200 instrument.

Experiments with varieties Christian, Cumidava, Roclas and Rustic took place in Brasov, in 2012 and 2013, years, very distinct from the point of view of climate during potato growing season. Extreme climate conditions during the growing season of potatoes can strongly disrupt the tubers growth processes, this being reflected on the yield structure. Very high temperatures and drought in 2012 have affected potato crops in the most important production phenological phase, the period of budding-flourishing, when susceptibility face to soil humidity is highest. During this period was the largest consumer of water. Because of these unfavorable circumstances, the new tubers suffered quantitative and qualitative depreciations by deformation, dehydration, second growth and sprouting. In the year 2013, characterized by alternate rainy periods with periods without rain and higher temperatures than normal, have determined foliage lush growth that could not self-holds and went into a very early ...

Contamination of crop plants with organic pollutants raises a growing interest in recent years; among the investigated pollutants, polycyclic aromatic hydrocarbons (PAHs) are of special concern because some of them are toxic and carcinogenic. In this context, the main purpose of this research was to establish the degree of contamination of corn grains with the 16 priority PAHs under three experimental cultures’ conditions: one with historical pollution, another located in an urban environment and a third reference one, located in an unpolluted area. Analytical determinations were performed by high performance liquid chromatography, highlighting the higher content of low molecular weight PAHs, mainly naphthalene, fluorene and acenaphthene; the high molecular weight PAH’ contamination is mainly due to indeno[1,2,3-c,d]pyrene and dibenzo[a,h]anthracene.

Viola tricolor L. species, originates from the temperate zones of Europe and Asia. In Romania it grows in the mountainous and subalpine areas, in wet meadows, hayfields, near the edges of forests and stony grounds. The raw material is the entire aerial part of the plant (Violae tricloloris herba or Jaceae herba), rootless and harvested at flowering. The product contains triterpenoid saponins, mucilages, salicylic acid esters, anthocyanin pigments, volatile oil, tannin, mineral salts. The presence of Viola tricolor saponosides and rutoside, acts as diuretic-and depurative and expectorant. It has anti-allergic and laxative actions. In the case of Viola tricolor L. seeds, originating in Germany, both the energy and germinative faculty decline with the age of seeds. Of the three types of substrates studied, the best proved to be variant V1 (peat) that showed the best sprouting of Viola tricolor L plants.

Hop (Humulus lupulus L.) is a clonally propagated, dioecious, perennial, climbing plant used commercially for their secondary metabolites. The resins containing α- and β-acids, and essential oils produced by the lupulin glands, present on the female flowers are used to add bitterness, aroma and flavour to beer. Recently, flavonoids, including chalcones and flavanones, of hops have been shown to exert a variety of biological activities, including oestrogenic and anticancerogenic characteristics. In this review, we provide a overview of the techniques and opportunities presented by the integration of plant biotechnology into hop improvement. The use of tissue culture techniques such as micropropagation, meristem culture, in vitro storage, adventitious shoot induction, callus culture and cell suspension culture in hops are briefly reviewed. The usefullness of genetic transformation technology to introduce novel traits into hop is also discussed

Winter wheat sown in the spring does not manage to produce grains. Vernalization is necessary for wheat to passfrom the vegetative phase to the generative phase. This happens in the same time with wheat “quenching”. Studies showthat vernalization can occur during germination, during plant growth or during seed formation and at the full maturity ofthe grains. Other research emphasizes that vernalization of wheat corresponds to the accumulation of total phytochromein the vegetative apex and to the accumulation of this pigment in the leaves, and the phenomenon of quenching is achievedby a transformation of the total phytochrome in less sensitive forms to dehydration of cells produced by frost.Vernalization of cultivated wheat is mainly controlled by three loci of the VRN1 gene, VRN-A1, VRN-B1 and VRN-D1located in the middle of the long arms of chromosomes 5A, 5B and 5D respectively. Spring wheat has alleles of the VRN1gene that reduce or eliminate the vernalization requirement. As resu...

Sweet lupine species have an important protein intake and have multiple uses on the food market, especially for vegetarian, vegan, non-GMO products, as well as for those without lactose, cholesterol, obtained with an ecological technology. Lupine protein contains all of the essential amino acids necessary for human nutrition, increasing the biological value of this crop. The reduction of the alkaloid content of lupine seeds, especially in white and blue lupine, is studied of approx. 100 years, being obtained their decrease from over 2% to less than 0.02%. The chemical composition of lupine seeds is favorable for functional foods that can replace milk, cheese or meat products. Thus, sweet lupine can be an alternative to soy. The use of sweet lupine has important phytotherapeutic effects in lowering blood cholesterol and uric acid in the body

The major role that soybeans may have in perspective is also related to the plant's attribution to fix the nitrogen in the atmosphere and to use it with high yield in the process of assimilation.To study the link between the quality characteristics considered in the three soybean varieties it was used the calculation of the correlation coefficients (r). The study of the existing links between the analysed characters is of great utility in the production by allowing the selection that simultaneously holds the combination of useful characters, but at the same time draws attention to the difficulty of achieving these requirements.
