DEVELOPMENT OF A SYSTEM TO STUDY PEROXIDASES DURING THE ROOTING OF LILAC SHOOTS PRODUCED IN VITRO
Shoot cultures of Syringa vulgaris cv. Madame Lemoine, initiated from nodal bud explants from two field grown plants expressing different levels of ease of propagation in vivo, have been used to study peroxidases in relation to rooting ability in vitro. Shoots of both clones were rooted without the use of exogenous auxins. The difference in rooting ability of in vivo shoots of the two clones was not maintained in culture. Dark pretreatment of cultured shoots prior to placing them on rooting medium resulted in poorer rooting. Lower peroxidase activity was associated with the dark pretreatment due mainly to differences in the anodic peroxidases. Higher peroxidase activity was observed in callus than in stem tissues.
