摘要:

SummaryIn a screen of seedlings of a worldwide range of 47 cultivars ofTriticum(mainlyT. aestivum) the concentration of the hydroxamic acid DIMBOA ranged between 1 and 8 mmol/kg fresh wt. In a bioassay in which alatae of the aphidSitobion avenaewere released among replicated test seedlings, there were highly significant correlations between aphid ‘preference’ and DIMBOA levels in the seedlings. The value of these results in work leading to the production of aphid‐resistant cultivars is disc
