evidence for cytokinin involvement in rhizobium (ic3342)-induced leaf curl syndrome of pigeonpea (cajanus cajan millsp.).a uniquely abnormal shoot development (shoot tip-bending, leaf curling, release from apical dominance, and stunted growth) in pigeonpea (cajanus cajan millsp) induced by a nodulating rhizobium strain, ic3342, is thought to be due to a hormonal imbalance. amaranthus betacyanin bioassay indicated that xylem exudate and leaf extracts from pigeonpea plants with rhizobium-induced leaf curl symptoms contained high concentrations of cytokinin relative to those in normal plants. radioimmunoassay (ria) o ...199116668086
insect odour perception: recognition of odour components by flower foraging moths.odours emitted by flowers are complex blends of volatile compounds. these odours are learnt by flower-visiting insect species, improving their recognition of rewarding flowers and thus foraging efficiency. we investigated the flexibility of floral odour learning by testing whether adult moths recognize single compounds common to flowers on which they forage. dual choice preference tests on helicoverpa armigera moths allowed free flying moths to forage on one of three flower species; argyranthemu ...200616846910
