摘要
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.
