Development of Prunus salicina cuttings grafted in situ in different susbtrates containing lombrihumus.
The objective of this study was to determine the effect of
substrates with lombrihumus on the development of plumb
cuttings growing in a nursery. Sections of Prunus salicina var.
Mariana 2624 were grafted on con P. salicina var. Methley
and planted on substrates containing lombrihumus. The
work was conducted at the Faculty of Agricultural Sciences,
UNAM, México, under fi eld conditions, from December
2002 to January 2003. A completely randomized was
employed, with factorial arrangement with four treatments
and four replications. The factors studied were the time of
cutting and grafting and the different types of substrates.
The variables measured were plant length, cutting diameter,
number of internodes, percent successful grafting, number of
leaves per plant, leaf area, perimeter and length. The optical
time for cutting preparation and grafting in situ under fi eld
conditions in Toluca, México, was January. The largest
grafting success was obtained with susbtrate composed of
20% peat (azolve soil), 30% perlite, and 50% lombrihumus.
With this technology, fully developed plumb plants can be
obtained in nine months.
