Vpliv različnih kritin plastenjakov na rast in razvoj paprike (Capsicum annuum L.) : magistrsko delo = The influence of different cover materials of greenhouses on growth and development of pepper (Capsicum annuum L.) : master of science thesis
Kacjan-Maršić, Nina
V nalogi so proučevane mikroklimatske razmere v zavarovanem prostoru, prekritem z etilenvinilacetatno (EVA) kritino, polietilensko (PE) kritino in polipropilenskim (PP) prekrivalom v primerjavi z ...rastnimi razmerami na prostem. Proučevan je njihov vpliv na rast in razvoj paprike. Zabeleženi so temperaturni ekstremi in relativna vlažnost zraka ter izračunana skupna količina toplotnih enot. Pod EVA kritino so bile minimalne in maksimalne temperature najvišje, prav tako količina toplotnih enot v času trajanja poskusa. Rastline pod kritinami so bile statistično značilno višje in imele statistično značilno več listov v primerjavi z rastlinami na prostem. Najvišji pridelek in največje število plodov/rastlino so imele rastline pod EVA kritino (800 g/rastlino oz 14 plodov/rastlino) in PE kritino (755 g/rastlino oz. 11,7 plodov/rastlino). Rezultati fizioloških meritev paprike kažejo, da obstajajo razlike v neto fotosintezi rastlin, ki rastejo pod različno kritino. Po podatkih iz literature med EVA, PP in PE kritinami ni večjih razlik v prepustnosti fotosintetsko aktivnega dela sevanja PAR, zato različna neto fotosinteza paprik ni posledica različne količine PAR v tunelih. Prav tako nismo zasledili statistično značilnega vpliva temperature zraka, temperature listov in relativne zračne vlage v času fizioloških meritev na neto fotosintezo paprike.
