Abstract
The response of mycorrhized and non-mycorrhized cranberry plants to water deficiency was evaluated.
The plants grown under greenhouse conditions were subjected to two water regimes: optimal irrigation (control) and reduced irrigation (drought stress treatment). Part of the plants were inoculated with ericoid mycorrhizal fungi before planting.
The response of the plants was determined morphologically (fresh weight of plant organs, number of shoots) and physiologically (photosynthetic activity, shoot water potential). In general, inoculation with mycorrhizal fungi enhanced photosynthetic activity (higher rates of gas exchange) of cranberry plants.
No significant differences in weight of shoots and number of runners were found between the inoculated and non-inoculated cranberry plants grown under different water regimes.
The plants inoculated with mycorrhizal fungi (both well-watered and drought stressed) produced higher number of uprights (fruit-bearing shoots).
