Title: Parameters that Influence Rooting and Survival of Peach Cuttings
Authors: G. Bartolini, P. Pestelli, L. Tazzari, and M.A. Toponi
Abstract:
To obtain a better understanding of the factors limiting the survival rate of self rooted cuttings in
peach (Prunus persica L. Batsch) after transplantation, some studies were performed.
First, was examined the influence of shoot orientation and side, on the stock plants and the diameter of the shoots from
which the hardwood cuttings were been taken.
The results indicated that cuttings made from plagiotropic
south-facing shoots, and, in general, the cuttings with a 6-10 mm diameter show higher rooting values
in comparison with smaller diameters.
In a second experiment performed with material chosen with the
parameters just defined we studied the effect on the cutting of basal heating (14 and 42 days) in combination with or without any previous cold treatment (90 days at 4°C) of the shoots.
The cold and basal
heating treatments may enhance the rate and amount of rooting.
The survival of the rooted cuttings can
be facilitated avoiding any trauma during transplanting.
The carbohydrate analyses indicate that the 6-10 mm diameter shoots contain a higher amount of soluble carbohydrates compared to the cuttings com
ing from cold treated shoots.
