    Efficient use of adequate level of nitrogen (N), phosphorus (P), and potassium (K) is essential and important part of the sustainable agricultural production. P deficiency is one of the most important yield-limiting issue in many parts of the world including large areas of the Carpathian basin area. Bread wheat is the largest crop in Hungary and its yield is significantly affected by nutrient status of the soil. This study was conducted to determine the optimum fertilizer levels of bread wheat in a low-P level, Calcisols, rich in organic matter content and N-Supply

    Triticale (Trilicosecale Wittm.) is a young, economical crop and its acreage has continuously been growing as the susiainability of farming is having superior status in all over the world. Today, triticale is a typical "on-farm" crop: farmers desire it as feedstock at their properties. Research reports however, revealed that this crop may be a useful, new ingredient in human consumption. This study is about the present situation and prospect of triticale production and utilization, particularly in human consumption. Lately, three environmentally sound triticale variety were developed in our institution for farmers for both low input, ecu-production and conventional agronomical systems. In this study, we examined the most important milling and baking characteristics of these new triticale varieties. Two of the tested triticales proved to have high alpha-amylase activities suggesting that using triticale component in target flour blends is desirable when improving the poor amylase activity of wheat components. The first Hungarian-bred spring triticale cultivar GK Idus has got exceptionallyhigh kernel hardness as well as protein content. Thus, GK Idus can be used fairly in development of various whole mail cereals and confectionary' industry. The results showed that all the tested triticales are suitable to use in human consumption, particularly to compose valuable flour blends using 10-50% triticale flour and 50-90% bread wheat flours as components. Triticale cultivar GK Szemes having exceedingly high loaf volume may be particularly valuable constituent in forthcoming baking industry

    Enhancement of a new method in cereal breeding programmes

    Homozygous doubled haploid (DH) plants and lines can be used in cereal breeding programmes. Methods based on androgenesis induction are a common way to produce homogenous basic material for variety development and genetic research purposes. Anther culture is a simple and rapid method for DH production in case of major cereal crops like barley and wheat. Oat is known as recalcitrant species for tissue culture response specially anther and microspore culture. Its low frequency DH production limits extensive application in breeding. Our aim was to start developing an improved protocol to generate acceptable number of DH lines for breeding. Many factors (low induction rate, essential manpower needed, plant regeneration problems and genotype dependence) hinder the development and application of the methods of in vitro androgenesis. Understanding of topic “in vitro response” and “plantlet regeneration frequency” are crucial factors in cereal science, too. Our aimed results of oat (Avena sativa L.) will open new genetic solutions in plant science, plant physiology and cell- and tissue culture of cereals and in the development of new varieties

    Influence of silicon on aluminium toxicity in common and durum wheats

    In acid soils, aluminium toxicity is the primary stress factor limiting the growth of plants. Silicon may reduce the toxic effects of Al in hydroponic culture. The objective of this study was to examine the effects of Al and Si treatments on the growth and potassium uptake of roots and transport to the shoots of an Al-resistant common wheat (Triticum aestivum L.) and an Al-sensitive durum wheat (T. durum Desf.). Seedlings were grown hydroponically, at pH 4.1, with different levels of Al and Si. Increased levels of Al (0-100 ÎŒ\muM) in the solution reduced root growth; however, shoot growth was not influenced, except in durum wheat in 7-d experiments. Si in the growth solution enabled plants to overcome Al toxicity symptoms. Seedlings of durum wheat proved to be more sensitive to Al and Si treatments. In short-term (6 h) uptake experiments, Si reduced the stimulatory effect of Al on K+^+(86^{86}Rb) uptake of roots, which indicated a definite Al-Si interaction, principally in the roots. In long-term (4 d) Si pre-treatment experiments, no post-effect was detected.Influence du silicium sur la toxicitĂ© de l'aluminium chez le blĂ© tendre et le blĂ© dur. Dans les sols acides, la toxicitĂ© de l'aluminium est la premiĂšre contrainte qui limite la croissance des plantes. Le silicium pourrait rĂ©duire les effets toxiques de l'aluminium en culture hydroponique. L'objectif de cette Ă©tude a Ă©tĂ© d'examiner les effets des traitements Ă  base d'aluminium et de silicium sur la croissance et l'absorption de potassium des racines et son transport vers les tiges d'un blĂ© tendre rĂ©sistant Ă  la toxicitĂ© de l'Al (Triticum aestivum L.) et d'un blĂ© dur sensible Ă  l'Al (Triticum durum Desf.). Les semis ont Ă©tĂ© effectuĂ©s en culture hydroponique Ă  un pH de 4.1 avec diffĂ©rents niveaux d'Al et de Si. L'accroissement des niveaux d'Al (0 Ă  100 ÎŒ\muM) dans la solution a rĂ©duit la croissance des racines, alors que la croissance des tiges n'Ă©tait pas influencĂ©e exceptĂ© pour le blĂ© dur dans les expĂ©riences de 7 jours. Le Si dans les solutions nutritives a permis aux plantes d'Ă©chapper aux symptĂŽmes de la toxicitĂ© de l'Al. Les semis de blĂ© dur ses ont montrĂ© ĂȘtre plus sensibles au traitement Ă  l'Al et Si. Dans les expĂ©riences d'absorption Ă  court-terme (6 heures), le Si a rĂ©duit l'effet stimulant de l'Al sur le prĂ©lĂšvement de K+^+(86^{86}Rb) par les racines qui indiquaient une interaction dĂ©finie Al-Si principalement dans les racines. Dans les expĂ©riences de prĂ©-traitement avec Si Ă  long terme (4 jours) aucun effet remanant n'a Ă©tĂ© dĂ©tectĂ©

    Intraoperative transfusion practices in Europe

    Transfusion of allogeneic blood influences outcome after surgery. Despite widespread availability of transfusion guidelines, transfusion practices might vary among physicians, departments, hospitals and countries. Our aim was to determine the amount of packed red blood cells (pRBC) and blood products transfused intraoperatively, and to describe factors determining transfusion throughout Europe. We did a prospective observational cohort study enrolling 5803 patients in 126 European centres that received at least one pRBC unit intraoperatively, during a continuous three month period in 2013. The overall intraoperative transfusion rate was 1.8%; 59% of transfusions were at least partially initiated as a result of a physiological transfusion trigger- mostly because of hypotension (55.4%) and/or tachycardia (30.7%). Haemoglobin (Hb)- based transfusion trigger alone initiated only 8.5% of transfusions. The Hb concentration [mean (sd)] just before transfusion was 8.1 (1.7) g dl and increased to 9.8 (1.8) g dl after transfusion. The mean number of intraoperatively transfused pRBC units was 2.5 (2.7) units (median 2). Although European Society of Anaesthesiology transfusion guidelines are moderately implemented in Europe with respect to Hb threshold for transfusion (7-9 g dl), there is still an urgent need for further educational efforts that focus on the number of pRBC units to be transfused at this threshold
