| Abstract:
A relatively high KCl supply at the end of the vegetation period, positively influences performance of long stored strawberry plants at - 2°C. A high substitution of SO42- by C1- in nutrient solution did not effect plant development. Analysis of plant sap shows a high correlation between supply and uptake of chlorides,with an antagonistic effect on other anions and a synergistic one on cations, no influence on pH, a positive effect on electrical conductivity and a negative effect on freezing point. After two months storage at - 2° C and planting in nutrient film, weight of KCl treated plants was higher; C1- content of older leaves was high, but in young leaves C1- content was at normal levels; fruit production was not significantly affected. | |
