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 effect of artificial ultraviolet (UV) and natural solar radiation on photosynthesis, res-. piration and growth was investigated in 14 red, green and brown macroalgal species on Spitsbergen. (Norway) during summer 1998. In June, maximum mean solar radiation at sea level was 120 W m-2 of. visible (370 to 695 nm) and 15 W m-' of UV radiation (300 to 370 nm), and decreased gradually until the. end of the summer.
