The Responses of Nutrient Uptakes in Different Organs of Narcissus Tazetta (L.) Grown Under Saline Conditions To Mycorrhizal Inoculation

Abstract

In this study, the effect of mycorrhiza (Glomus intraradices N.C. Schenck & G.S. Sm.) inoculation on the micronutrient and macroelement uptakes in different organs of daffodil (Narcissus tazetta L.) grown under saline conditions is examined. For this purpose, Narcissus tazetta plant grown in the climate chamber was treated with sodium chloride (NaCl) at three different concentrations such as salt -free (S0), 34 mmol (S1) and 68 mmol (S2) in mediums with mycorrhiza (M+) and without mycorrhiza (M-). At the end of the experiment, the uptakes of sodium (Na), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu) uptakes in the bulb, root and leaves of the plant were analyzed. The effects of salt and mycorrhiza interactions on the N uptakes were statistically significant at the 5% level in bulbs. The effects of salt applications were found significant at 1% level for all nutrients uptakes of roots except Cu uptake (5%). The effects of interactions among salt and mycorrhiza were found significant at 5% level for P, Ca and Mn uptakes and at 1% level for Mg, Fe and Cu uptakes of leaves statistically. Increasing doses of sodium chloride had statistically negative effects on nutrient uptakes of different organs except Na and K uptakes of bulbs. Mycorrhiza applications generally increased nutrient uptakes of daffodil's roots and leaves under salinity conditions. The interactions between salt and mycorrhiza were significant for N in bulbs, for N, P and Fe in roots and for P, Ca, Mg, Fe, Mn and Cu in leaves. The decreases in these nutrients uptakes by 68 mmol NaCl applications were lower in mycorrhiza applications than those in non mycorrhiza applications.
