Nine macadamia cultivars were used to pollinate'Kau'.The results showed that there were significant differences(p<0.05)in fruit set,diameters,kernel recovery,percentages of firstgrade kernel,amino acid composition,and contents of amino acids,mineral elements,crude proteins,ash and water among different pollinators.However,there were no obvious effects on fruit shape index,average kernel weight,contents of fatty acids,crude fat and total sugars.O.C and918 could be used as pollinators because of high fruit se...
