The effect of total solar. radiation on nutrient concentration (mean values for 11 chrysanthemum cultivars) is. summarized in Figs 2â9. The increase of radiation (in MJ m-2) caused decreased. concentration of nitrogen, phosphorus, potassium, calcium, magnesium, cuprum and. boron in chrysanthemum leaves.
The total concentrations of macro- and. microelements in plant tissue were determined. To find the relationship between nutrient. concentration in plant tissue and radiation, data were analysed using simple linear regression. models. Radiation had an effect on nutrient concentration in chrysanthemum leaves. The. highest determination coefficient R2 for P and Ca, the lowest for N and K were calculated.
