Abstract
Arbuscular mycorrhizal fungi, namely, Glomus mosseae and Glomus intraradices, and an endophyte, Piriformospora indica was used to assess the growth of two varieties (JS 335 and TAMS 98-21) of soybean (Glycine max L.) subjected to drought stress. Chlorophyll a fluorescence was measured by Handy PEA (plant efficiency analyzer) and analyzed by Biolyzer programme. The JIP-test (Chlorophyll a fluorescence rise at J I and P steps) was applied to evaluate in vivo vitality based on in vivo biospectroscopy, which supplied images, spectra and kinetics.We report that in JS-335 variety of soybean, G. intraradices induced the highest drought resistance followed by G. mosseae and P. indica, whereas in TAMS 98-21 variety, G. mosseae induced highest drought resistance followed by G. intraradices and P. indica.
Key words: Glomus mosseae, Glomus intraradices, Piriformospora indica, Glycine max L., arbuscular mycorrhizal.
