Bird damage and glucosinolates of canola (Brassica napus L.)
To better understand the relationship between bird damage and glucosinolates content of rapeseed,43 bred lines from the National Regional Trail of Rapeseed (2013) were investigated,and8 injured lines at bud stage were analyzed on their glucosinolates.Results Showed that 13 rapeseed lines had more than 23 μmol/g glucosinolates (in rapeseed cake),and they had no bird damage.Others with lower glucosinolates than 23μmol/g had bird damage in different degrees.Their damage index ranged from 14.3％ to 50.0％.Amongthem,8 injured lines had damage index of 25.0％ to 77.22％.The damage was more serious on lines with less seedglucosinolates.T test result showed that,6 aliphatic glucosinolates profiles had significant difference between injured and healthy lines.Aromatic and indolyl glucosinolates profiles had no difference between these two types of lines.Results also showed that the aliphatic profiles had negative correlation with the index of bird damage,indicating that aliphatic profiles were the main contributing factors.
