ABSTRACT

This study was carried out to compare contents of resorcinolic lipids both
in grains and roots of four winter wheat cultivars, harvested in different parts
of Poland. Moreover, under in vitro conditions, the effects of various
temperatures on accumulation of these phenolic compounds in roots of tested cereal
cultivars were estimated.


Most tested cultivars (Mikula Turnia and Natula) contained similar amounts
of alkylresorcinols in their grains, up to 463.6 mg kg-1. The only exception
was Satyna, in which kernels the level of resorcinolic lipids was markedly lower
than in cultivars from south-eastern Poland (Mikula and Turnia).


In turn, alkylresorcinol occurrence in roots of 10-day-old
seedlings of cultivars tested was noticeably different between cultivars and
was markedly dependent on temperature conditions. It was found that the lowest
tested temperature (18°C)
mainly decreased the alkylresorcinol accumulation in wheat roots. Moreover, it
is the first report about the presence of these compounds in root system of cereals.

Key words: alkylresorcinols, kernels, root system, Triticum aestivum L..
