Methodology of ApMV, ACLSV and ASGV diagnostic in apple and pear cultivars and rootstocks by ELISA
Svoboda, Jiří ; Polák, Jaroslav
The presence of Apple mosaic virus (ApMV), Apple chlorotic leaf spot virus (ACLSV) and Apple stem grooving virus (ASGV) is tested in apple and pear cultivars and rootstocks according to the EPPO recommendation by evaluating symptoms on tree indicators after grafting. This method requires two or three years of planting. For that reason it was prepared and optimised serological testing the presence of ApMV, ACLSV and ASGV by ELISA as a reliable specific methodology. Research results obtained in Crop Research Institute, Prague approve suitability of ELISA for the detection of these viruses in a specific tree tissue during a specific vegetation period. Developed methodological procedures are appropriate especially for state control and supervision laboratories and they are necessary for the certification scheme of fruit trees.

Alternative phosphorus nutrition of plants
Mikanová, Olga ; Šimon, Tomáš
The methodology summarizes the basic information on applicability of phosphorus solubilizing bacteria for inoculation of field crops. Specific procedures of isolation, screening, selection and maintaining of bacterial strains are described. The technology of inoculant production, and application techniques are involved. The methodology offers the use of inoculants as an alternative plant nutrition. Results of practical experiments show that P-solubilizing bacteria increase the utilization of phosphorus. Plant growth promoting microorganisms in the inoculant also support the root system and consequently uptake of all nutrients by plants.
