| Abstract:
Floral bud distribution was studied in ten self-compatible almond selections by counting all the buds on several branches. Bud density, the number of buds per unit length of branch, varied from 0.46 to 1.02 bud cm-1. Bud productivity, the number of buds per cm2 of cross section of the main branch sustaining all the smaller branches, varied from 49 to 128 bud cm-2. Ranking of selections based on bud density was different from that based on bud productivity, showing that shoot morphology, shoot thickness and flower production on spurs or on one-year shoots affect these variables. As a general rule, the longer the one-year shoot, the lower the number of buds per unit length, showing that the elimination of the longer shoots by pruning is advisable because this facilitates light penetration into the canopy and increases the number of flower buds. | |
