Developmental process of sun and shade leaves in Chenopodium album L.
Fractionation of crude petroleum ether extract of the leaves of Chenopodium album Linn lead to the isolation of β-sitosterol (1), lupeol (2) and 3 hydroxy nonadecyl henicosanoate (3). Their structures were elucidated by spectroscopic methods such as UV, IR, NMR and LCMS. Compound 2 and 3 were isolated for the first time from this plant.متن کامل
BACKGROUND A Chenopodium album L. biotype surviving in atrazine-treated Serbian corn fields (VC) was compared against atrazine-susceptible (S) and atrazine-resistant (R) standards. RESULTS Atrazine (2 kg ha(-1)) killed S and VC shoot biomass 15 days after treatment (DAT), but R was only suppressed by 42% and survived 8 kg ha(-1). Atrazine at 2 kg ha(-1) only inhibited VC height by 60% as agai...متن کامل

In Chenopodium album, leaf excision and light both increase urease (EC. 220.127.116.11) activity. Dithiothreitol (DTT), reduced glutathione (GSH), cysteine and diazoinedicarboxylic acid bis(N,N-dimethylamide) (diamide) activated the crude enzyme. In contrast, crude urease was inhibited by phenylmethylsulphonyl fluoride (PMSF) and Na-p -tosyl-L-lysine chloromethyl ketone HCl (TLCK), suggesting the pres...متن کامل
Chenopodium album seedling emergence studies were conducted at nine European and two North American locations comparing local populations with a common population from Denmark (DEN-COM). Mortality risk. Weedy plant life history conforms to the time of mortality risk from either the environment (e.g. frozen soil in the winter) or cropping systems practices (e.g. herbicide use). C. album life his...متن کامل
