GROWTH, YIELD AND FRUIT QUALITY OF STRAWBERRIES AS AFFECTED BY WATER SUPPLY |

| Abstract:
The effect of long-term water stress on vegetative and generative growth of Fragaria ananassa Dutch. cv. Korona was investigated. The plants were cultivated in sand-culture with four different grades of modified Hoagland solution. In the control treatment (100 % of the modified solution) the plants received nutrient solution between 9 a.m. and 8 p.m. every day. The solution was circulating continuously in the containers. Different grades of water stress were induced by supplying 75, 50 and 25 per cent of the daily water consumption of the control. The 100% water supply promoted growth of leaves, crowns and runners. Yield was reduced in water stressed plants because of a decreased mean fruit weight and a diminished fruit number. Fruit maturity was accelerated in water stressed plants. It is concluded that water deficit has a strong effect on vegetative and generative growth of strawberry plants. | |
