Effect of GA and NAA on the yield and quality of Macadamia

赤霉素和萘乙酸对澳洲坚果产量和品质的影响结果表明,赤霉素和萘乙酸的配合施用能显著提高澳洲坚果的产量、一级果仁率和单果重。其中,盛花期喷施20 mg/L赤霉素及幼果期喷施0、20、40 mg/L萘乙酸的单株产量分别为6.42、12.98、7.40 kg,比对照提高35.16%、173.26%、55.79%;一级果仁率分别比对照提高8.10%、8.07%、9.26%。单果重随着赤霉素喷施浓度的升高而增加。另外,盛花期喷施40 mg/L赤霉素、幼果期喷施0、20、40 mg/L萘乙酸在一定程度上也可提高澳洲坚果的产量和品质。

The effect of GA and NAA on the yield and quality of Macadamia nut was studied ：in this paper. The results showed that the combined application of GA and NAA could improve the yield, the first class nut rate and single nut weight. Using 20 mg/L GA at popular florescence and 0, 20, 40 mg/L NAA at young fruit period, the sigle plant yield reached 6.42, 12.98, 7.40 kg and 35.25%, 173.22%, 55.74% higher than the contrast, respcetively. The first class nut rate was 89.78%, 89.75%, 90.74% and 8.10%, 8.07%, 9.26% higher than the contrast. And the single nut weight increased with the increasing of GA concentration. Besides, using 40 mg/L GA at popular florescence and 0, 20, 40 mg/L NAA at young fruit period could also enhance the yield and quality of Macadamia nut to a certain extent.
