Collection and evaluation of some rich in oil spontaneous crucifer species in situ

Abstract

116 seed samples of five spontaneous crucifer species were collected in 2008–2010. The highest amount of oil was found in seeds of Descurainia sophia (32,2%) and Erysimum. cheiranthoides (30,6%). Fatty acids were dominated by unsaturated acids (oleic, linoleic and linolenic) in D. sophia (71,4%), E. cheiranthoides (63,5%) and Cakile. baltica (62,7%), by erucic acid – in Alliaria petiolata (49,3%) and Thlaspi arvense (35,6%) seeds oil. The least content of glucosinolates was in C. baltica (9,4 mol. g-1) and E. cheiranthoides (16,5 mol. g-1) seeds and the biggest one in T. arvense (48,3 mol. g-1). E. cheiranthoides distinguished by stability of biochemical seed traits, T. arvense by lability of oil and glucosinolates amount in seeds
