The effects of temperature, sucrose concentration, mineral nutrients and plant growth regulators on germination of pollen and growth of pollen tubes were studied using 6-year old macadamia trees as experimental material. It was showed that the optimal temperature and sucrose concentration were 25℃ and 10%, respectively; as compared with IAA and 2,4-D, GA3 at 20 mg·L-1 stimulated the germination of pollen significantly; and Zn at 10 mg·L-1, Mo at 5 mg·L-1, B at 10 mg·L-1, Mn at 40 mg·L-1 and Ca at 30 mg·L-1 were most favorable for the germination of pollen.
