Abstract: | Ethylene production and growth of callus cultures of lavandin (Lavandula offidnalis Cham x Lavandula latifolia Villars) cv.
Grosso were examined. Callus lines, derived from various kinds of primary expiants (shoot tip, leaf and calyx), exhibited
differences in ethylene production patterns independent of callus growth. Moreover these differences could not be ascribed
to the expiant source. Within a line, ethylene pattern paralleled callus growth curve. Variations in ethylene evolution were
induced in shoot tip callus by means of ACC, AVG and varied amounts of 2,4-D in the culture medium. Following all these treatments
callus growth was not altered. Hie decrease in 2,4-D concentration caused changes in Chl a and water content of the tissues. |
