Lämpötilan ja poutajakson vaikutus jauhosavikan (Chenopodium album L.) ja viljan väliseen kilpailuun

Abstract: Koe I. Tutkimukset, jotka koskivat keskenään kilpailevaa jauhosavikkaa ja kauraa osoittivat seuraavaa: 1. Jauhosavikka ja kaura kehittyivät huomattavasti nopeammin 24° kuin 12° C:ssa. Kumpikin laji tarvitsi 24° C:ssa alkukehitykseensä samat lämpötilasummat 2-lehtiasteelle saakka. Siitä eteenpäin kehittyäkseen jauhosavikka tarvitsi pienemmät lämpötilasummat kuin kaura. Lämpötilan ollessa 12° C kauran alkukehitykseen 2-lehtiasteelle saakka riitti pienempi lämpötilasumma kuin jauhosavikalle. Alhainen lämpötila hi… Show more

“…There was very little rainfall in the 32 days after sowing, resulting in extremely poor and uneven emergence of crop and weeds. Erviö's (1972) results from pot trials showed that a dry period at early growth stage of wheat had no significant effect on the growth of C. album but reduced the biomass of wheat significantly. Maganti et al (2005) also demonstrated that C. album thrives better under dry conditions than do cereal grains like barley.…”

“…In Finland, C. album is one of the most frequent and troublesome annual weed species in organic spring cereals (Salonen et al 2001(Salonen et al , 2011. Chenopodium album thrives under dry conditions (Maganti et al 2005), but under favorable conditions spring cereals are strong competitors against C. album due to their rapid development during early growth stages (Erviö 1972).…”
