Influence of different type of artificial lighting on germination and germination energy of lamb's lettuce and garden cress

Abstract

Cilj ovog rada je bio utvrditi utjecaj LED i FLUO osvjetljenja na klijavost i energiju klijanja matovilca i kres salate, te na masu i visinu njihovih klijanaca. U istraživanju je korištena sorta matovilca Verte de Cambrai i naturalno sjeme kres salate. Sjeme je posijano te postavljeno na naklijavanje u komoru opremljenu s LED i FLUO osvjetljenjem. LED lampe su bile opremljene crvenim (650-670 nm) i plavim (440-460 nm) LED diodama. Istraživanje je provedeno u Laboratoriju za povrćarstvo, cvjećarstvo, ljekovito i začinsko bilje Poljoprivrednog fakulteta u Osijeku. Kod matovilca je nakon statističke obrade podataka utvrđen značajan utjecaj vrste osvjetljenja na energiju klijanja i klijavost koje su bile više pod LED lampama te na visinu i masu klijanaca gdje su veće vrijednosti zabilježene pod FLUO lampama. Kod kres salate je utvrđena značajno veća visina klijanaca pod FLUO osvjetljenjem, dok vrsta osvjetljenja nije značajno djelovala na ostale ispitivane parametre.The aim of this paper was to determine the influence of LED and FLUO on the germination and germination energy of lamb's lettuce and garden cress as well as on weight and height of their seedlings. In this study seeds of lamb’s lettuce cv. Verte de Cambrai and natural seed of garden cress were used. Seeds were sown according to standard laboratory procedure. Germination testing was conducted in plant growth chamber which was illuminated with LED and FLUO lamps. The LED lamps were equipped with red (650-670 nm) and blue (440-460 nm) LED diodes. The research was conducted in a Laboratory for Vegetable, Flowers, Medicinal and Spice Herbs at the Faculty of Agriculture in Osijek. According to data statistical analysis lighting type had significant influence on the germination and germination energy of lamb’s lettuce which were higher under LED lamps, as well as on height and weight of lamb’s lettuce seedlings which were recorded to be higher under FLUO lamps. Seedlings of garden cress were significantly higher under the FLUO lamps, whereas there were no significant differences between seedlings weight, germination energy and germination
