Physiological biosafety assessment of genetically modified canola on weed (Avena sativa)

The present study was carried out for the assessment of physiological biosafety and effects of genetically modified (GM) canola on Avena sativa, which is a common weed plant of South Asia. Methanolic extracts of GM and non-GM canola were assessed on seed germination and growth of A. sativa under sterilized conditions. The extracts were treated with 3%, 5%, and 10% concentrations of methanol. Results showed that the extract of GM canola increases the number of roots and root fresh weight. However, root length was significantly decreased. Similarly, a significant rate of increase was observed in shoot fresh weight and shoot length of A. sativa by treatment of GM canola. Emergence percentage, germination index, and emergence rate index show a significant effect of decrease when treated with GM canola.
