Amaryllis (Hyppeastrum Herb.)is one of the bulbous ornamental plants that is distributed around the world. Regarding the cultivation of ornamental plants in landscaping, it is essential to use salinity-resistant ornamental species. Less research has been done on the impact of salt irrigation on the growth and development of bulbous ornamental plants like this plant. So, in order to investigate salinity tolerance in amaryl-lis, the experiment was done with five salinity concentrations [control (distilled water) with EC = 0dSm-1, and electrical con-ductivity (EC) at 2, 4, 6 and 8 dSm-1] with four replication on leaf freshness, leaf length and width, proline, nitrogen (N), po-tassium (K), phosphorous (P) content, and peroxidase enzyme activity. Results showed that increasing salinity led to decreased leaf nutrients and growth parameters like plant height, shoot mass, leaf length, width, mass, and corm mass, and increased proline and peroxidase activity.

Abstract

Amarilis (Hippeastrum Herb.) je ena izmed čebulastih okrasnih rastlin, ki je razširjena po vsem svetu.. Pri uporabi okrasnih rastlin v ozelenjevanju je pomembno, da se uporabljajo na slanost odporne okrasne rastline, pri čemer je bilo opravljenih le malo raziskav o vplivu zalivanja s slano vodo na rast in razvoj čebulastih okrasnih rastlin. Z namenom preu-čiti toleranco amarilisa na slanost je bil izveden poskus s petimi slanostmi in štirimi ponovitvami. Obravnavanja s slanostmi so bila: kontrola (distilirana voda) z električno prevodnostjo EC = 0dSm-1 in obravnavanja z električno prevodnostjo (EC) 2, 4, 6 in 8 dSm-1.V rastlinah so bili ocenjeni/izmerjeni naslednji pa-rametri: svežost listov, dolžina in širina listov, vsebnost prolina, dušika (N), kalija(K), fosforja in aktivnost peroksidaze. Rezul-tati so pokazali, da se je s povečevanjem slanosti zmanjševala vsebnost hranil v listih, zmanjševali so se tudi rastni parametri kot so višina rastlin, masa poganjkov, dolžina, širina in masa listov, masa celotnih rastlin, povečali sta ste vsebnost prolina in aktivnost peroksidaze.
