Il Ritmo dell'attività vegetativa dei germogli e delle radici nell'arancio dolce.

In this paper the Authors refer the results of trials conducted in 1972-
'73 on vegetative behaviour of young container grown « Tarocco» sweet
orange trees under climatic conditions of northern Sardinia.
Observations evidenced that shoot and root growth was mainly influenced
by soil and air temperature.
Canopy growth was characterized by three different growth periods,
while root growth occurred only in two stages, with alternate periods between
shoot and root growth well evidenced.
In the winter, on the other hand, both root and shoot growth stopped
because of unfavorable temperature conditions.
