EVALUATION OF THE EFFECTS OF PLUM ROOTSTOCKS ON TIME OF FLOWERING IN APRICOT (‘SHAHROUDI’ AND ‘LASGERDI’ CULTIVARS) TREES

This study was conducted in the Khorasan Agricultural and Natural Resources Research Centre during 1999-2004 with the main purpose of bloom delaying of apricot trees.
The treatments were 6 rootstocks (‘Myrobalan’, ‘Mariana’, ‘Saint Julien’, ‘Bokhara’, ‘Dargazi’ and ‘Shahroudi’) with 2 apricot scions cultivars (‘Shahroudi’ and ‘Lasgerdi’). A factorial experiment was laid out in completely randomized blocks with 4 replications.
All data were subjected to analysis of variance and Duncan’s multiple range tests were used to compare the treatment means.
Results showed that the time of flowering of the ‘Shahroudi’ cultivar on ‘Myrobalan’ and the ‘Lasgerdi’ cultivar on ‘Saint Julien’ rootstock was delayed 4 and 8 days respectively.
The results also showed that the period of flowering in both cultivars on ‘Saint Julien’ rootstocks was increased (11 days) compared to the control (5 days).
