PRODUCTION AND QUALITY OF ROSA HYBRIDA CV SONIA IN ROCKWOOL AT THREE LEVELS OF ELECTRICAL CONDUCTIVITY COMBINED WITH TWO LEVELS OF RELATIVE HUMIDITY |
| Authors: | R. Brun, A. Settembrino |
| Abstract:
Rose plants were grown in rockwool at three EC and two RH levels. Optimum flowers production was obtained at the lower EC level and at the higher RH level. Commercial classification was unaffected. Leaf diffusive conductance, CO2 fixation rate and transpiration were unaffected or better when fog system was used. Mineral content of leaves was analysed. | |
