                            <p>In this study, the effects of light sources of different wavelengths on the growth of red curly leaf salad (Lactuva sativa var. Crispa) plants were examined and the results were discussed. The study was carried out with a total of 12 repetition, each three sowed seeds in four pots in 6 compartments (A, B, C, D, E and F). The light sources were adjusted to be 16 hours of daytime and 8 hours of night, and the ambient temperature was kept constant at 24°C. Single color LED light sources in the research; Mixed LED light sources with cool white (A), warm white (C), red (B), [33.3% red + 16.7% far red + 16.7% green + 16.7% blue + 16.6% UVA] (E) and [50% red + 50% blue] (F) 5 different LEDs and cool white fluorescent lamps (D) were used. According to the results of the experiment, the plants with the longest leaf length were obtained in the “B”, the plants with the widest leaves were obtained in the “D”, and the plants with the highest number of leaves were obtained in the “C, D, F” compartments. According to the Lab scale used to determine the color criteria, while a and b values are statistically insignificant, the groups with the highest L value is the lettuce grown in the “B, D, E” group. Lettuce grown in “F” light group gave the closest parameters to the same type of lettuce offered for sale in terms of distance between leaf nodes, number of leaves, color and visuality.</p></trans-abstract>

Crispa) bitkisinde büyümeye olan etkileri incelenmiş ve elde edilen sonuçlar tartışılmıştır. Çalışma, 6 adet bölme (A, B, C, D, E ve F) içindeki dörder saksıda üçer adet ekili olan tohum olmak üzere toplam 12 tekerrür ile sürdürülmüştür. Işık kaynakları 16 saat gündüz, 8 saat gece olacak şekilde ayarlanmış ve ortam sıcaklığı 24°C’de sabit tutulmuştur. Araştırmada tek renk LED ışık kaynakları; soğuk beyaz (A), sıcak beyaz (C), kırmızı (B) ile karışım LED ışık kaynakları; [%33.3 kırmızı + %16.7 uzak kırmızı + %16.7 Yeşil + %16.7 mavi + %16.6 UVA] (E) ve [%50 kırmızı + %50 mavi] (F) olmak üzere 5 farklı LED ve soğuk beyaz floresan lamba (D) kullanılmıştır. Deneme sonuçlarına göre, yaprak boyu en uzun bitki, “B”, en geniş yapraklı bitkiler, “D”, yaprak sayısı en çok olan bitkiler ise “C, D, F” bölmelerindeki denemelerde elde edilmiştir. Renk kriterlerinin belirlenmesinde kullanılan Lab skalasına göre istatistiki açıdan a ve b değerleri önemsiz çıkarken L değeri en yüksek olan bölmeler “B, D, E” bölmelerinde yetişen marullardır. Yaprak boğum arası mesafe, yaprak sayısı, rengi ve görselliği açısından ticari olarak satışa sunulan aynı tür marula en yakın parametreleri veren “F” ışık bölmesinde yetişen marullar olmuştur.</p></abstract>
