RHIZOSPHERE MICROBIOTA PROFILE CHANGES WITH DIFFERENT GENETIC TYPES OF TOMATO SPECIES
Use of improved seeds (hybrids, transgenic, etc.) in agriculture is a common practice in our days. Resulted plants could improve crop yield or to develop in less adequate geoclimatic conditions, responding those to challenges raised by global change. However, at now there are limited information on...

Use of improved seeds (hybrids, transgenic, etc.) in agriculture is a common practice in our days. Resulted plants could improve crop yield or to develop in less adequate geoclimatic conditions, responding those to challenges raised by global change. However, at now there are limited information on potential impact of such plants on soil properties and microbiota. Considering that microbiota are key mediators of soil functions and ecosystem processes it is important to fulfil such gaps. The objective of this study was to identify if different genetic varieties of Cherry tomato (Solanum lycopersicum), grown in same conditions, could influence root exudates (mainly carbohydrates) and rhizosphere microbiota profile. Randomized complete block rhizo-box experiment was performed with identic soil under similar growing conditions of genetic varieties Cherry tomatoes. PLFA and carbohydrates were analysed on GC-FID. In soil where tomatoes were grown the total PLFA amount was approximately two times higher compared with that detected from control (669.1 nmolg-1), which means that tomato root rhizosphere and exudates could influence soil microbiota.
