Photosynthesis and productivity of potato plants in the conditions of different spectral irradiation

E (λ max 450±5 nm, 470±5 nm) light on growth processes and activity of photosynthetic apparatus in potato plants of the Nevskii early variety. It was made a conclusion, that application of light-emitting diode irradiators in controllable conditions of phytotron may be useful technique during potato growing subject to changes of spectrum composition in plant ontogenesis.
