Abstract
Na laboratorijskem polju Biotehniške fakultete je od konca junija do konca avgusta 2023 potekal poskus, pri katerem smo ugotavljali vpliv slanostnega stresa na solato gojeno na hidroponskem sistemu NFT ob prisotnosti antagonistične glive Trichoderma sp.. Poskus je bil sestavljen iz štirih obravnavanj: obravnavanje s povečano vsebnostjo NaCl v hranilni raztopini (24 mM NaCl) in sadikami predhodno tretiranimi s pripravkom Trifender® Pro (v nadaljevanju S1+Tr_Kor), obravnavanje s povečano vsebnostjo NaCl v hranilni raztopini (24 mM NaCl) in s pripravkom Trifender® Pro, dodanim v hranilno raztopino (v nadaljevanju S1+Tr_Hr), obravnavanje s povečano vsebnostjo NaCl v hranilni raztopini (24 mM NaCl) brez prisotnosti pripravka (v nadaljevanju S1) in kontrola (hranilna raztopina brez NaCl). Morfološke meritve opravljene na svežih rastlinah so pokazale, da dodatek glive Trichoderma sp. ni izboljšal rasti rastlin. Največjo maso rozete so imele solate, pridelane v kontrolnem obravnavanju (242±22,5 g/rastlino), najmanjšo pa v obravnavanju S1+Tr_Hr (128,8±6,5 g/rastlino). Največjo vsebnost suhe snovi je imela solata pri S1+Tr_Hr (6,0 %), najmanjšo pa solata iz kontrolnega obravnavanja (5,7 %). Najmanjša vsebnost nitratov je bila izmerjena pri solati iz obravnavanja S1 (583±76,3 NO3-/g sveže mase), največja pa je bila pri solatah iz kontrolnega obravnavanja (837,5±61,2 NO3- /kg sveže mase). Vsebnost fotosintetskih pigmentov je bila največja pri obravnavanju S1+Tr_Hr, kateremu je sledilo S1+Tr_Kor. Najmanjša vsebnost pigmentov je bila pri solatah iz obravnavanja S1.

Title:
Influence of salinity on yield and quality of lettuce (Lactuca sativa) in the presence of the antagonistic fungus Trichoderma sp.
Abstract:
From the end of June to the end of August 2023, an experiment was carried out in the laboratory area of the Biotechnical Faculty to determine the effects of salinity on lettuce grown in a hydroponic NFT system in the presence of the fungus Trichoderma sp. The experiment consisted of four treatments: 24 mM NaCl in nutrient solution and seedlings previously treated with Trifender® Pro (S1+Tr_Kor), treatment with 24 mM NaCl and with the fungus Trifender® Pro in the nutrient solution (S1+Tr_Hr) and 24 mM NaCl in nutrient solution (S1), control (0 mM NaCl). Morphological measurements on fresh plants showed that the addition of Trichoderma sp. did not improve plant growth. Lettuce from the control treatment showed the highest weight (242±22.5 g/plant) and the lowest in the S1+Tr_Hr treatment (128.8±6.5 g/plant). The lettuce in the S1+Tr_Hr treatment had the highest dry matter content (6.0 %), while the lettuce in the control treatment had the lowest (5.7 %). The lowest nitrate content was measured in the lettuce of the S1 treatment (583±76.3 mg NO3- kg fresh weight), while the highest content was measured in the lettuce of the control (837.5±61.2 mg NO3- kg fresh weight). The content of photosynthetic pigments was highest in lettuce from treatment S1+Tr_Hr, followed by S1+Tr_Kor. The lowest pigment content was found in lettuce from treatment S1.
