of haptotropic response in seedlings than in tendrils. Thus in Agro- stemma
githago the excitation can be conducted for a distance of 8 to 4 cm., in Helianthus
annuus for about 7 cm. and in Ricinus com- munis for 5 to 10 cm. On the other

Scheme1.21 Scheme1.22 Moreover, after transfer the free ligand can be
recovered by crystallization. The mechanistic proposal for the transfer reaction is
based on an initial h4 to h1 haptotropic migration (Scheme 1.22). A catalytic
