Leaf surface compound fromBrassica oleracea (Cruciferae) induces oviposition byPieris brassicae (Lepidoptera: Pieridae)
SummaryChemicals present on the surface of cabbage (Brassica oleracea L.) leaves were extracted by dipping these leaves for 3 s in dichloromethane followed by a 3 s dip in methanol. When offered inExpand

Increased Induction of Adventitious Rooting by Slow Release Auxins and Elicitors
Indolebutyric acid (IBA) is the auxin that is commonly used for induction of adventitious roots. Our experiments show that IBA is not active itself but exerts its action by conversion (β-oxidation)Expand
