Abstract

The growth of rocket Diplotaxis tenuifolia (L.) DC. profiles was studied during 30 days of growing in the chamber under different lighting regimes; T5_ peak at 630 nm, LED1_ peak at 545 nm and LED2_ peak at 599 nm. There were no significant differences in dry weight after 15 days, however, from day 15 to 30, the increase in dry weight was significantly biggest under LED2. This agrees well with estimated average leaf area (LA) per plant (43.83 cm2 ), the increase of LA (39.70 cm2 ) and total fresh weight (7.898 g per plant). The regression analysis revealed the strongest correlation between the dry weight and PPFD_R light intensity (0.792**), showing the positive effect of additional LED lighting in comparison with standard T5 light.
