Root quality increasing and absorption improvement of some nutrients with arbuscular mycorrhiza (Glomus mosseae) application in New Guinea impatiens (Impatiens hawkeri) cuttings

To evaluate the rooting of New Giunea impatiens (Impatiens hawker stem) cuttings under arbuscular mycorrhiza (Glomus mosseae) and its effect on nutrient elements absorption, an experiment as factorial in complete random design with three replications in the greenhouse was established. Experiment factors were four levels of synergistic mycorrhiza in 0, 11 and 22 percent (as powder) and 20 percent (as solution, v/v). Cutting were collected from seed propagated stock plant (Devine Scarlet Red, F1) and planted in medium mycorrhiza incubated pots contributed in 50% of peat moss, 40% of perlite and 10% percent of rice husk (v/v). One month after planting, rooting percentage, root length, number and volume and root fresh and dry matter were evaluated. Results showed that unless rooting percentage, the significant difference in 0.01 probability observed in all evaluated traits. The most root length and volume (32 cm and 34.66 mm3) and root fresh and dry matter (26.49 and 0.73 g) was related to 22% percent treatment. Five months after planting, other group of rooted cuttings was evaluated for element absorption content. The most leaf nitrogen (2.6%), phosphorus (0.419%), potassium (2.66%), zinc (73.52 mg/kg) and copper (18.77 mg/kg) content observed in 22% treatment. In this experiment mycorrhiza application in medium (as powder) showed better results compared to solution treatment.
