Daržovių daigų auginimas po aukšto slėgio natrio lempomis papildant šviesos spektrą 447 nm komponente.

The objective of our studies was to investigate effect of solid-state short-wavelength sources of blue light in combination with high-pressure sodium lamps for growing of vegetable seedlings. Cucumber hybrid 'Mandy', tomato hybrid 'Cunero' and sweet pepper cultivar 'Reda' were used for investigation. There was compared growing of vegetable seedlings under high-pressure sodium lamps ‟SON-TAgro„ (PHILIPS) and under these lamps supplemented by blue light solid-state illuminators with LHXL-LR3C(Lumileds Lighting, USA) light-emitting diodes (447 nm). It was established that vegetable (cucumber, tomato, sweet pepper) seedlings were lower. Supplemental blue light during growing of vegetable transplant accelerated formation of flower buds. Significant after-effect of supplemental blue light on vegetable yield was not established. [ABSTRACT FROM AUTHOR]
