Deviations of some nutrient concentrations in different parts of safflower cultivars during growth stages.

摘要

An experiment was conducted in Turkey, to study the concentrations of P, K, Fe, Zn and Mn during growth and development in different parts of safflower cultivars Dincer, Yenice, 5-154 and Yerli. Both P and K concentrations in all plant parts (except P concentration in head) decreased from shooting to maturity stages. P concentrations in heads were higher than other parts at every stage of growth and development in all cultivars. Fe concentrations in the roots, stems and leaves showed deviations during the growth stages. Zn levels in all parts of the cultivars showed a similar tendency without big deviations until the first blooming, after which Zn concentration showed irregular increases and decreased at harvest (except root Zn concentration). Mn levels of the root, stem and head in all cultivars decreased through the end of the period. However, in the leaves, Mn concentration generally increased through the harvesting stage..
