The effects of green and far red light on germination of common chickweed (Stellaria media (L.) Vill.) seeds were compared to determine a possible mechanism of activity of green light in the germination process of chickweed. A brief irradiation with far red light on the first day of imbibition was found to inhibit germination at a certain percentage but it was followed by a stimulating effect, which became evident on the second day of imbibition. Green light was not found to inhibit germination and its stimulating effect began simulataneously with the stimulating effect of far red light. The results indicate a possible role of phytochrome A in stimulation by green light.
Upoređivan je uticaj zelene i tamnocrvene svetlosti na klijanje semena mišjakinje (Stellaria media (L.) Vill.) da bi se utvrdio mogući mehanizam delovanja zelene svetlosti na ovaj proces kod mišjakinje. Pokazano je da kratkotrajno osvetljavanje tamnocrvenom svetlošću tokom prvog dana imbibicije inhibira klijanje u određenom procentu, a zatim počinje da deluje stimulativno, što je potpuno očigledno tokom drugog dana imbibicije. Zelena svetlost ne inhibira klijanje, a njen stimuliativni efekat počinje u isto vreme kada i stimulatvni efekat tamnocrvene svetlosti. Rezultati ukazuju na moguću ulogu fitohroma A u stimulativnom delovanju zelene svetlosti.
