The impact of water deficit on selected physiological characteristics of juvenile hop plants (Humulus lupulus L.)

Popis výsledku v původním jazyce

Hop plants are very demanding as concerns sufficient amount of water, and therefore the aim of the experiments was to monitor the impact of water deficit on the exchange of gases in the juvenile hop plants. The impact of water deficit was observed in controlled greenhouse conditions where the plants of Žatecký poloraný červeňák (SAAZ)?Osvaldův klon 72? were cultivated in 15 l containers in two groups ? the control group and the stressed group. In the stressed group, irrigation was interrupted for a period of nine days and then seven-day rehydration followed. It is apparent from the obtained results that after irrigation is interrupted, the levels of stomatal conductivity, transpiration and photosynthesis rate significantly decrease. After nine days ofstress, the stomatal conductivity reached almost a zero level and the photosynthesis rate was 5.320 mikromol CO2 m-2 s-1 and the transpiration rate was 0.987 mol H2O m-2 s-1. When irrigation was resumed, the stomatal conductivity, transpi
