Effects of Lead Contamination on Nutrient Contents of Hyacinth (Hyacinthus orientalis L. c.v. “Blue Star”)

Abstract

The aim of this study was to determine the effects of lead on nutrient contents of hyacinth (Hyacinthus orientalis L. c.v. "Blue Star") in lead contaminated media. This research was conducted in a completely randomized experimental design with three replications in green house conditions. Four doses of lead as control, 20 mg kg^-1, 40 mg kg^-1, 80 mg kg^-1 were applied to each pot having 500 g soil:sand mixture in 2:1 ratio. The irrigation was made by distillate water and hoagland solution was applied for fertilization. At the end of the experiment the highest Mg, Fe and Cu contents of hyacinth bulbs were obtained as 0.59 %, 36.00 mg kg^-1 and  3.40 mg kg^-1  in control  while the highest K (9.72 %), Zn (32.27 mg kg^-1) and Ca (2.69 %) were in 40 mg kg^-1 and 80 mg kg^-1 lead applications respectively. On the other hand the highest Mg (1.46 %) and Cu (13.75 mg kg^-1) contents of hyacinth leaves were obtained in control. The highest K (2.41 %), Ca (4.82 %), Fe (129.86 mg kg^-1) and Zn (50.14 mg kg^-1) contents of leaves were obtained in lead contaminated media. Lead applications generally increased Fe and Zn contents and decreased of Cu content of hyacinth leaves.
