A NEW ROMANIAN POTATO VARIETY, CEZARINA AND ITS SPECIFIC TECHNOLOGY
National Institute of Research and Development for Potato and Sugar Beet Brasov is working to create potato varieties align to international demand. The new created variety Cezarina have a very good yield capacity, is very well adapted to soil and climate condition of Romania on the base of testing activity on the network of the State National Institute for Testing and Registration of Varieties (ISTIS) before homologation. The research was carried out between 2016 – 2018 using the classical breeding scheme for potato and applying a specific technology. The starch content and the processing quality were determinated in a specialized laboratory and late blight (Phytophthora infestans) resistance and viruses resistance were determinated in fields. The resistance to black wart (Schynchitrium endobioticum) was determinated to National Station of Testing Pojorâta. Variety resistance to diseases, especially late blight, helps to reduce the number of treatment which is cost saving and enviromental protection
RESPONSES OF SOME NEW ROMANIAN POTATO VARIETIES TO THE IN VITRO HIDRIC STRESS
Plant performance and crop yield are negatively affected by drought and heat in the context of the global climate changes. The present study was carried out to the National Institute for Research and Development Brasov, Romania, to observe the tolerance of three potato varieties to in vitro water stress. In vitro water stress negatively affects leaf size and number, number of internodes, stem and root length.Microbuts resulting from uninodal segmentation of in vitro-developed plantlets were inoculated into tubes containing Murashige-Skoog medium, enriched with naphthyl acetic acid and 20 g / l sugar and various amounts of agar.A high reduction of morphological parameters was observed to Castrum variety, susceptible for water deficit, while Ervant variety is more tolerant to drought than the other two varieties. The results indicated that simulation of drought stress under in vitro conditions constitutes a convenient way to study the drought effects on potato plants
THE EFFECT OF BASIC NPK FERTILIZATION AND SOME NITROGEN FORMS APPLIED TO POTATO AND SUGAR BEET CROPS AFTER PLANTING
The identification of complex fertilizer assortments and the development of differentiated methods of application of nitrogen fertilizers to potato and sugar beet crops are major objectives of fertilization technologies, in order to reach the maximum production potential in terms of quantity and quality. Nine variants of fertilization recipes have been experimented with NPK complexes in 2014 and 2015 that included three NPK complexes for basic fertilization, at soil preparation before planting/sowing and fertilizers with various forms of nitrogen for phaseal fertilization applied to potato and sugar beet. The effect of basic NPK fertilization and some forms of nitrogen applied after planting the crops has been studied on the Christian potato variety and Clementina sugar beet variety. The experimental data recorded in 2014-2015 show that all fertilizer recipes tested on potato and sugar beet respond with production increases
Le désir de langue. Les dimensions poétique et politique de la diglossie dans le roman « Le jardin de verre » de Tatiana Țîbuleac
Still relevant today via mobility and the multicultural environment as the constitutive elements of our globalized societies, the reflections around “the cumbersome problem of the genius of languages” (Cassin 2016) join and enrich the question of living together and building oneself. In the field of literature or human sciences, the thought of the practice of languages in a situation of diglossia has forged an imaginary which often connects the passage from one language to another to a balance of power and a tension of identity. We propose an analysis of the symbolic values of the dilemma between the Romanian language and the Russian language which is at the heart of the diegesis of the novel Grădina de sticlă [The Glass Garden] by Tatiana Țîbuleac. Published in Romanian by Éditions Cartier de Chișinău and translated into several languages, including French and Spanish, the book was awarded the European Union Prize for Literature in 2019. The fictional world and the language of writing describe a symbolic abyss: the author describes in Romanian the fight with the Russian of a Moldovan orphan who is trying to rebuild herself between the two languages. In a very colorful style, the novel deploys a po(ï)etics of “between”, which also has a political dimension
Imaginarul rețelelor de socializare și poetica distanțării în romanul Interior Zero de Lavinia Braniște
After 2004, the year when Facebook was created, the issue of social networks as increasingly widespread and generalized ways of communication and relationship in society also invested in the field of literature, becoming an ingredient of the literary diegesis. To the extent that the writers of the so-called digital generation, respectively the one born and formed directly in the society of communication technologies, can no longer ignore the presence of social networks in the daily lives of created characters, what kind of imaginary literature does this create? Our analysis focuses on how the narrative voice in Lavinia Braniște's novels establishes a meta-critical relationship with social networks, especially in the universe of the first novel, Interior Zero, published in 2016. We are interested in finding out to what extent, in the age of millennials and the virtualization of existence, literature is a subtle form of ontological resistance through catharsis
New potato varieties obtained at National Institute of Research and Development for potato and sugar beet Braşov
Potato is a plant with great ecological plasticity, nutritious, tasty and inexpensive, which is the staple food of many
peoples. Potato use efficiently use the modern technologies and provides the greatest amount of food per unit of area. In
terms of energy is of great importance for human consumption in a variety of ways of preparation and industrialization.
National Institute of Research and Development for Potato and Sugar Beet Brasov is working constantly to create new
potato varieties adapted to changing climatic conditions, with high yield, suitable for the processing industry, to satisfy
the both quantitative and qualitative needs of consumers. Regarding the genetic complex structure of potato (2n = 4 x =
48 chromosomes) and the segregation of the desired character in the offspring produced by sexual hybridisation,
creating new varieties of potato requires a long period (10-12 years) and a large volume of activity (chance for
registration of a new variety is 1 to over 100.000 seedlings). The key objective was to select varieties immune to wart
disease, with high resistance to other diseases (mainly potato late blight), with good agronomic and cooking qualities.
As the result of breeding work three new varieties were produced: Azaria, Darilena and Asinaria. The varieties are
conceived for autumn-winter consumption, being suitable for most culinary preparations, from salad, pommes frites to
mash potatoes. The potato varieties were breed using the hybrid cross method followed by individual clonal selection,
according to the classical scheme of potato breeding. The best potato clone was selected from many others. The
resistance to wart disease was tested at Pojorâta Station (Suceava) and the resistance to late blight and viruses were
determinated in the fields and laboratories of NIRDPSB Brasov. Also to NIRDPSB Brasov it has been determined the
culinary quality of potato tubers by assesing their behavior to boiling. The yield capacity in different environmental
conditions and also the ecological plasticity of the varieties were tested in State Institute for Variety Testing and
Registration network
PARTIAL RESULTS REGARDING THE INFLUENCE OF SOME TECHNOLOGICAL ELEMENTS ON THE YIELD OF DRIED HERBA TO THE PRIMULA OFFICINALIS HILL. SPECIES
Sustainable use of natural resources is one of the great challenges of our time. Thus, there is a return to nature, to homeopathic medicine and to phytotherapy. Primula officinalis Hill, has been used since ancient times in popular medicine due to its many healing properties. The main purpose of the study is the introduction into the culture of the species Primula officinalis Hill. The research started in 2016 by accumulating information on the existing genetic resources. The plants necessary for the establishment of the experiments were brought from the spontaneous flora of Braşov Country. The study aimed to establish the optimal breeding mode, the optimal planting time and nutrition space. These technological links influence the the plant yield but also on the content in active principles. The paper presents partial results regarding the elaboration of cultivation technolog
Responses of different potato late blight control technologhies to the use of noninvasive methods
The present study was conducted to investigate potato late blight influence on leaf chlorophyll level. Field experiments
were carried out in the years 2014-2016 to the National Institute of Research and Development for Potato and Sugar
Beet – Brasov, Romania. It was used a complet randomized block design with four replicates, two planting distance
between plants on row and different fungicides.
At measurements in early July in 2014 and 2016, the varieties had close SPAD values (SPAD 39.5 and 40.1 for Roclas
variety, SPAD 41.9 and 37.5 for Christian variety), which were lower at all varieties compared to the values measured
in 2015, at which the SPAD average values were 47.8 at Riviera, 48.0 at Roclas and 49.4 at Christian.
In 2014, following the measurements made to Roclas and Christian varieties, there was a close correlation between the
SPAD values and the number (0,752 *), respectively the weight of the tubers at nest (0,882 **), while the correlation
was negative between the SPAD values and the weight of the aerial part of plants (-0,722) *. In this year correlations
between SPAD average values, total yield and commercial one were insignificant. The only year of the experimental
cycle in which SPAD average values from variants correlated significantly was 2016, the year leading to the highest
SPAD correlation coefficients - totalyield (0,706 *) and SPAD - commercial yield (0,656 *
