[The effect of chronic UVB-irradiation on the growth, development and productivity of fodder beet].
In a field study in 1989, the effect of additional UV-B-irradiation (with an intensity of 0.34, 0.49 or 0.77 W/m2, daily exposure of 17.3, 26.7 or 39.1 kJ/m2, and total exposure of 1457.3, 2248.8 or 3285.6 kJ/m2) on the growth, development and productivity of fodder beet var. Eckendorf yellow was investigated. The three levels of irradiation caused a delay of plant growth and a significant reduction of plant height (18-26%), air-dry weight of leaves (32-43%), wet weight of leaves (48-52%), and weight of root-crops (48-50%).
