INFLUENCE OF LED LIGHTING ON GERMINATION OF CARROT AND SPINACH

Cilj ovog istraživanja bilo je utvrditi utjecaj LED rasvjete i fluorescentne rasvjete na klijavost, energiju klijanja, kao i na masu i visinu klijanaca . U ovom pokusu korišteno je sjeme mrkve (Flakke 2) i sjeme špinata (Viroflay). Klijanje i energija klijanja ispitani su pomoću standardnog laboratorijskog postupka. Masa i visina klijanaca zabilježeni su na kraju testiranja klijanja. Statistička analiza podataka pokazala je da FLUO rasvjeta znatno povećala visinu klijanaca mrkve. Međutim, LED rasvjeta je znatno povećala klijanje, masu klijanaca i visinu kod špinata. Dakle, može se zaključiti da su različite vrste rasvjete manje ili više pogodne za različiti uzgoj povrća. Sukladno rezultatima, LED rasvjeta može se preporučiti kao izvor svjetlosti za sporo klijajuće sjeme kao kod špinata.The aim of this study was to determine the influence of LED lighting and fluorescent lighting on germination, germination energy as well as on seedlings fresh weight and height. In this trial the carrot (cv. Flakke 2) and spinach seeds (cv. Viroflay) were used. Germination and germination energy were tested using standard laboratory procedure. Seedlings weight and height were recorded at the end of germination testing. Statistical analysis of data showed that FLUO lighting significantly increased carrot seedlings height. However, LED lighting significantly increased germination, seedlings weight and height in spinach. Therefore, it can be concluded that different types of lighting are more or less suitable for different vegetable specie. Also, according to these results, LED lighting can be advised to have as a light source when testing slow germinating seeds like in spinach
