Summary

CONDITIONS FOR IN VITRO GERMINATION OF JOJOBA POLLEN WERE OPTIMIZED IN ORDER TO STUDY THE INFLUENCE OF STORAGE TEMPERATURE ON VIABILITY. THE OPTIMUM INCUBATION TEMPERATURE RANGE FOR POLLEN GERMINATION WAS 298 TO 303 K (25 TO 30 DEG C). POLLEN STORED AT 277 K (4 DEG C) MAINTAINED ITS INITIAL VIABILITY FOR 10 WEEKS, FOLLOWED BY A GRADUAL DECREASE IN GERMINATION TO 70% IN 17 WEEKS AND 0% AFTER 22 WEEKS. POLLEN STORED IN LIQUID NITROGEN FOR 2 YEARS RETAINED A GERMINATION PERCENTAGE AS HIGH AS THAT OF FRESH POLLEN. THE CRYOGENICALLY STORED POLLEN, WHEN USED IN CONTROLLED POLLINATIONS, PRODUCED NORMAL FRUIT SET COMPARABLE TO THAT WITH FRESH POLLEN.
