Abstract

The investigations of growth rhythm, dry matter production, leaf area development and root/shoot ratio of dominant reed bed species, grown in a greenhouse in hydroponic cultures during winter and spring are described. Data on air temperature, relative humidity and density of incorning solar radiation were recorded during the whole season. All species planted in autumn (in a warm greenhouse) presented a pronounced thermoperiodism, i.e. weak growth caused by an incomplete period of dormancy. The winter-planted specimens developed into normal and vigorous plants. TheR/S ratio may be a relatively constant characteristic of species, but only for a given growth phase.
