AB  - Characterisation of bean genotypes, particularly local landraces is important for ongoing breeding programs, especially for drought tolerance. Susceptibility to drought is emphasized when bean is grown as a stubble crop and sown at the middle of summer. The aim of this study was to compare variability of ten bean genotypes to optimal (25 degrees C) and higher (30 degrees C) temperatures in combination with optimal (80%) and reduced (40%) field water capacity (FWC), from the point of growth (root and shoot length and fresh matter accumulation) and thermodynamic parameters of free energy (calculated parameter after drying at 60 degrees C, 105 degrees C and 130 degrees C) during the early seedlings stage. Significant and positive correlation between root length and fresh matter with free energy at symplast and chemically bound water occurred under temperature stress (i.e. 30 degrees C). Root growth and elongation were affected by drought stress, i.e. under a combination of high temperature (30 degrees C) and water deficit (40% FWC). Based on higher energy consumption, the ability of shoot to continue a growth in stressful conditions could be possible to achieve, as was confirm through significant and positive correlation between evaluated growth parameters in shoot and free energy of free water. It could be concluded that most of the examined dry bean accessions expressed some sensitivity to stress applied. Among genotypes tested, local landrace zecak expressed lesser susceptibility to stresses applied. Accession Maksa was more tolerant to changes at cytoplasmic level, while Medijana and Sataja 425 expressed root i.e. shoot stress tolerance. Those accessions could be considered as potentially drought tolerant genotypes.

AB  - The present study describes the developed filter layer method for the consistent determination and identification of the natural occurrence of Pyrenochaeta terrestris in maize roots. The field experiment was set up to establish the applicability, accuracy and efficiency of this method for the pathogen isolation from roots of maize grown under different agroecological conditions. According to this method, the 10- to 15-mm long tissue sections, mainly cut at the margin of lesions developed in roots, were placed on two layers of moisten filter paper in Petri dishes and incubated for 6-7 days under laboratory conditions, 25 +/- 2 degrees C and daylight. The unique reddish-purple (beet-red) pigmentation was used as an indicator of the fungal incidence in infected roots, which facilitated a succeeding confirmation of the pathogen on PDA at 25 degrees C in the dark and on CLA in the alternating 12 h light (fluorescent and near-ultraviolet light)/12 h dark conditions. Obtained results showed that the filter layer method was very effective for the P. terrestris detection and that it could be applied for a rapid assessment of response of maize genotypes, environmental and seasonal effects on the fungal growth on roots and the fungal distribution. Advantages of this method for the detection and quantification of P. terrestris in relation to the methods described in the literature include: a) low investments, because many root samples can be tested immediately at the same time; b) results can be obtained rapidly (6-7 days after sampling); and c) minimal interference by other fungi or bacteria.
