Abstract
Measuring amount of shikimate and chlorophyll content of hybrids of maize, line of soybean, C. canadensis and L. rigidum populations were examined after application of 1 kg a.e. ha-1 of the herbicide product TOUCHDOWN® [active ingredient: glyphosate trimesium salt (syn. sulfosate), 500 g L-1]. Samples collected 2, 4 and 6 day after treatment. Changes in amount of shikimate in treated plants vs control were significant for S plants and nosignificant for R plants. Content of chlorophyll in tretaed plants were statisticaly lower vs nontreated plant in every tested poulations/lines/hybrids, except in hybrids of maize (differences were not significant).
Merenje sadržaja šikiminske kiseline i hlorofila kod hibrida kukuruza, linija soje, populacija C. canadensis and L. rigidum je obavljeno nakon primene 2 kg a.m. ha-1 herbicida TOU­CHDOWN® [aktivna materija: glifosat trimezijum so (sin. sulfosat), 500 g L-1]. Uzorkovanje je urađeno 2, 4 i 6 dana posle primene. Promene sadržaja šikiminske kiseline kod tretiranih biljaka u odnosu na ne tretirane su bile značajne kod svih S biljaka i nisu imale značaja kod R biljaka. Sadržaj hlorofila kod tretiranih biljaka je statistički bio niži u odnosu na sadržaj kod ne teretiranih biljaka kod svih testiranih populacija/linija osim kod hibrida kukuruza (razlike nisu bile statistički značajne).
