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.
