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 field 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 field 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.
