DEVIATIONS OF SOME NUTRIENT CONCENTRATIONS IN DIFFERENT PARTS OF SAFFLOWER CULTIVARS DURING GROWTH STAGES IBRAHIM ERDAL* AND HASAN BAYDAR**
Abstract:
The objective of this research was to examine the concentrations of
P, K, Fe, Zn and Mn during growth and development in different parts
of 4 safflower varieties. The nutrient concentrations of safflower showed
variations depending on the varieties and plant parts at different stages
of growth and development. Both phosphorus and potassium concentrations
in all plant parts (except P concentration in head) decreased from shooting
to maturity. Phosphorus concentrations in heads were higher than other
parts at every stage of the growth and development in all varieties.
Iron concentrations in the roots, stems and leaves showed quite deviations
during the periods. Zinc levels in all parts of varieties showed the
similar tendency without big deviations until the first blooming. After
this stage concentration of Zn showed irregular increases and decreased
at harvest again (except root zinc concentration). Mn levels of the
root, stem and head in all varieties decreased through the end of the
period. But in leaf, Mn concentrations increased through the harvest
generally.
