Appropriate selection and well-timed measurement of plant developmental, morphological physiological parameters are essential to maximize efficacy minimize time consumption experiments. To select for the most sensitive indicators drought or salt stress, three independent pot experiments with diverse setups were analysed 20–20 measured parameters. Parameters growth, phenology symbiotic interactions, visual stress symptoms, photosynthetic activity, nutrient composition vitality studied result...

Diversity and colonization levels of naturally occurring arbuscular mycorrhizal fungi (AMF) in onion roots were studied to compare organic conventional farming systems the Netherlands. In 2004, 20 fields sampled a balanced survey between two regions, namely, Zeeland Flevoland. 2005, nine ten additionally surveyed AMF phylotypes identified by rDNA sequencing. All plants colonized, with 60% for 84% hyphal as grand means. Zeeland, from had higher fractional than those fields. Onion yields...

Root endophyte fungi of ericaceous plants were compared with those obtained from the dominant grass in Dutch heathlands, Deschampsia flexuosa. We investigated phylogenetic relatedness these and their effects on nutrient uptake both Calluna vulgaris D. flexuosa seedlings synthesis trials vitro. Molecular analysis based nuclear ribosomal internal transcribed spacer (ITS) region sequences revealed that four root endophytes belonged to Helotiales (Ascomycetes). The majority isolates (68 %) also...

A greenhouse pot experiment with different phosphorus supply was conducted to study growth, photosynthesis and free polyamine (PA) content in Plantago lanceolata L. plants relation arbuscular mycorrhizal (AM) colonization. Inoculum of Glomus fasciculatum (BEG 53) used. Inoculated had high colonization intensities which were related the P supply. Non-mycorrhizal (NM) showed a typical yield response curve for availability. Dry masses (M) higher at lowest soil than those NM plants, but opposite...

Soybean (Glycine max L. Merr.) is regarded worldwide as indisputably one of the most important crops for human food and animal feed. The presence symbiotic bacteria fungi essential soybean breeding, especially in low-input agricultural systems. Research on cooperation between different microbial symbionts a key to understanding how health productivity plant supported. effectivity dual tripartite agents was investigated two pot experiments cultivars with special regard compatibility. In...

Expression profiling of two paralogous arbuscular mycorrhizal (AM)-specific blue copper-binding gene (MtBcp1a and MtBcp1b) isoforms was performed by real-time quantitative polymerase chain reaction in wild-type Medicago truncatula Jemalong 5 (J5) during the development with Glomus intraradices for up to 7 weeks. Time-course analysis J5 showed that expression both MtBcp1 genes increased continuously correlated strongly colonization intensity arbuscule content. MtPT4, selected as a reference...

The influence of organic and conventional farming agroecology on the diversity functioning indigenous soil microbial communities was examined using a multifactorial analysis based an extended minimum data set classical status functional tests.Main physicochemical properties selected microbiological indicators, quantity heterotrophic or aerobic spore-forming bacteria, basal substrate-induced respiration, catabolic activity with MicroResp TM , fluorescein diacetate enzyme were characterized.A...

A pot experiment was designed to demonstrate that the parallel, single-frequency detection of electrical capacitance (CR), impedance phase angle (ΦR), and conductance (GR) in root–substrate systems an adequate method for monitoring root growth some aspects stress response situ. The wheat cultivars 'Hombar' 'TC33' were grown a rhyolite-vermiculite mixture under control, low, medium, high alkaline (Na2CO3) conditions with regular measurement parameters. photochemical efficiency (Fv/Fm) SPAD...

This study evaluated the concurrent application and results of root electrical capacitance (CR) minirhizotron (MR) methods in same plant populations. The container experiment involved three winter wheat cultivars, grown as sole crops or intercropped with pea under well-watered drought-stressed conditions. activity (characterized by CR) MR-based length (RL) surface area (RSA) were monitored during vegetation period, flag leaf chlorophyll content was measured at flowering, shoot dry mass (SDM)...

This study aimed to survey the long-term effects of fertilization practices on functional diversity soil microbiota. A 60-year experiment with mineral fertilizers, farmyard manure and combined treatments was sampled in two consecutive years maize ( Zea mays L.) wheat Triticum aestivum L.). Soil chemical properties, plant growth physiological parameters were measured. The MicroResp TM method applied assess community level profiles (CLPPs) rhizosphere soil, arbuscular mycorrhizal fungal (AMF)...

The modified nucleotide content of the ribosomal RNAs in wheat is greatly influenced by light. rRNAs etiolated seedlings contain far fewer derivatives. composition characteristic green plants develops gradually as a result irradiation. In course experiments changes state modification 5.8S and 18S were examined during greening seedlings. Three types minor nucleotides, O2'-methyladenosine, O2'-methylguanosine pseudouridine found rRNA leaves, none which was detected wheat. nucleotides appeared...

Összefoglalás: A kommunikáció az élet valamennyi formájában és szintjén létező jelenség, ezért természetes, hogy a növények is kommunikálnak, ami régóta foglalkoztatja növénybiológusokat

Symbiotic effectivity of two- and tripartite symbiotic agents was investigated in a pot experiment on three soybean ( Glycine max L. Merr.) cultivars with special regard to compatibility. Host plants were single co-inoculated two Bradyrhizobium japonicum strains commercial arbuscular mycorrhizal fungal (AMF) products. Significant differences found infectivity the microsymbionts. While AMF inocula very poor, benefits treatments more expressed than that rhizobial ones. In case inoculants we...

The effects of cadmium (Cd) stress and arbuscular mycorrhizal fungus (AMF) inoculation were investigated in wheat [ Triticum aestivum L. cv. TC-33] under controlled conditions. experiments aimed to reveal what responses belong the different levels Cd load growth medium (0; 1; 2,5 5 mg kg - 1 substrate). To detect effect stress, we compared plant physiological indicators measured with both situ destructive methods. Electrical capacitance (C R ) was evaluated during as a method indicate...
