Název v původním jazyce

Effect of drought stress and mycorrhizal inoculation on the growth, photosynthetic activity and water use efficiency of leek (Allium porrum L. 'Gigante Suizo').

Popis výsledku v původním jazyce

During the experiments it was examined two irrigation levels: 1. optimal water supply-the irrigation activation by available water capacity (AWC) < 65 %; 2. drought stress irrigation activation by AWC < 45 %) and inoculation of plants by the vesicular arbuscular mycorrhizal fungus Glomus in leek culture. The eff ect of treatments on the photosynthetic rate (A), transpiration rate (E), water use effi ciency (WUE), biomass production (weight, dry matter content of diff erent plant part), size of pseudostem, leaf area and specifi c leaf area (SLA) was observed. The drought stress had eff ect on all observed parameters: it decreased the photosynthetic and transpiration rate (A: from 5.04-5.37 to 3.33-3.43 mikromol CO2.m-2. s-1, E: from 1.78-1.91 to 0.99-1.03 mmol H2O.m-2.s-1 in the average of 5 measuring date), the weight total fresh weight of plants: from 355-453 g to 152-255 g), and the Leaf area, the length and diameter of pseudostem, too. The WUE, the dry matter content and the thickne
