Differential growth of almond pollen tubes in three environments

Socias i Company R.

Pollen tube growth dynamics was followed in emasculated flowers maintained in three different environments: (i) on the original branches in the field; (ii) on cut branches placed at constant temperature in chambers; and (iii) on individual flowers placed on floating meshes in trays in the same constant temperature chambers. Self-compatible ('Cambra') and self-incompatible ('Bertina') cultivars were studied. Both were self- and cross-pollinated with 'Marcona' pollen that is inter-compatible with both of them. The results showed that the dynamics of pollen tube growth was the same in the three environments and that the only difference was due to the compatibility of the pollination. These results support the utilization of individual flowers on trays to study the compatibility relationships of almond pollination, thus resulting in freeing this study from the weather conditions in the field and in saving space in the chambers at constant temperatures.
