Effect of Drought Stress and Glomus Inoculation on Selected Physiological Processes of Sweet Pepper (capsicum Annuum L. Cv. 'Slávy')

JEZDINSKÝ, A., VOJTISKOVA, J., SLEZAK, K., PETŘIKOVA, K., POKLUDA, R.: Eff ect of drought stress and Glomus inoculation on selected physiological processes of sweet pepper (Capsicum annuum L. cv. ’Slavy’). Acta univ. agric. et silvic. Mendel. Brun., 2012, LX, No. 3, pp. 69–76 Sweet pepper (Capsicum annuum L. ‘Slavy‘ F1) plants were colonized by the vesicular-arbuscular mycorrhizal fungus Glomus and grown in two irrigational levels: 1. optimal water supply (the irrigation activation by available water capacity (AWC) < 65 %); 2. drought stress (irrigation activation by AWC < 45 %). In the fi eld experiment selected physiological parameters, such as photosynthetic rate, transpiration rate, stomatal conductance and water use effi ciency were observed. The highest photosynthetic activity was observed in the fi rst measuring date in both experimental years (2010: 7.5–8.1 μmol . m −2 . s −1
