Adventitious root formation can be inhibited in stem cuttings
of Pisum sativum L. (pea), an easy-to-root species, if the apical
and lateral buds are removed. Application of exogenous auxin to
the apical stump can replace the rooting stimulus produced by the
buds. Root number was reduced by 50 to 100%...
Many investigators have suggested that current photosynthate
supply can limit adventitious root formation on leafy cuttings.
Accordingly, studies were undertaken to determine the effects of
altering photosynthesis and carbohydrate levels on adventitious root
formation by leafy cuttings of a number of different species.
Pea cuttings rooted at high CO₂ (1800...
The effects of light incident on leafy cuttings is
quite complex because' light influences several factors
which may affect root formation. One effect of light is
to influence the carbohydrate status of the cutting by
influencing photosynthesis. The role of current photosynthate
in the rooting of leafy cuttings is uncertain....
