Strawberry plants (cv. Elsanta) were originated by micropropagation. Rooting was conducted ex vitro in multiplates. Inoculum with endomycorrhizal fungi (AMF) was added to the substrate, thus symbiosis developed simultaneously with root formation. The multiplates were placed under low and high light intensity (35 and 150 micro mol m-2 s-1, respectively). The effects of different light intensity and mycorrhization were evaluated morphologically and physiologically, using Chl a fluorescence method. Acclimatized plants kept under high-light conditions grew intensively until development of photoinhibition, when they decline. Mycorrhization improved plant growth, especially those from shade. Parameters of Chl a fluorescence: Fo, Fv/Fm, Y and Fv/Fo showed continuous destruction of photosynthetic apparatus of the plants growing under 150 micro mol m-2 s-1. Mycorrhization enhanced, to some degree, tolerance of the plants to light stress.. |
