Based on the results, the highest value of flower stem length (64.70 cm), corolla diameter (6.17 cm), vase life (22.11 days) and chlorophyll b (3.05 μgml-1 g-1 FW) was obtained with the humic acid 300 ppm+ 50g mycorrhizal fungi treatment. On the other hand, the highest value of corolla length (6.68 cm), activities of catalase (36.72 μmol/mg-1min-1) and peroxidase (15.76 μmol/mg-1min-1) were also observed. Chutichudet et al., (2010) showed that mycorhiza fungi treatment could increase stem height in the gerbera cut flower. Neilsen et al., (2004) reported that the treatment of 400 mg/l humic acid increased amount of chlorophyll in the plants. On the base of the results, we concluded that humic acid, Mycorrhiza fungi and endophytic Piriformospora indica fungi treatments coused obvious effects on the black rose cut flower. Application of biologic fertilizers and symbiotic bacteria increased nutrient absorption. Therefore, consumption of the chemical fertilizers was reduced. Also treatments increased vaselife of flowers. Effect of humic acid on root growth was wonderful, as increased root volume. Humic acid increases plant tolerance to biotic and abiotis stresses and mycorhiza fungi helps in absorbing non soluble elements. Therefore, qualitative and quantitative parameters of black rose cut flower were increased.
