９个澳洲坚果品种在粤西、桂南２个试验区的平均单株产量均比在澳大利亚的低，在粤西沿海地区，成年树平均株产约是澳大利亚的 １／３的水平； １６ ａ树龄果园 ５个品种前 ７ ａ平均株产以ｋｅａｕｈｏｕ（２４６）较好，其次为 Ｉｋａｉｋａ（３３３）、 Ｈｉｎｄｅ（Ｈ２），而 Ｋｅａａｕ（６６０）、 Ｋａｋｅａ（５０８）较差； １１ａ树龄果园 ６个品种前７ ａ平均株产量以 Ｋａｕ（３４４）、Ｉｋａｉｋａ（３３３）较好，其次为 Ｏｗｎ Ｃｈｏｉｃｅ，而Ｍａｕｋａ（７４１）、Ｍａｋａｉ（８００）、Ｋａｋｅａ（５０８）较差。 ２个品比试验初产期３ ａ统计， Ｈ２、Ｏｗｎ Ｃｈｏｉｃｅ、３３３产量显著高于其它品种，２４６，５０８，３４４，８００差异不显著，９个品种在南亚所的产品质量达到国外主产区的标准。
The average yield per plant of nine macadamia varieties in two experimental areas in western Guangdong and southern Guinan was lower than that in Australia. In the western Guangdong coastal areas, the average adult plant production was about 1/3 of that in Australia; 16 a Keauhou (246) was the best in the first 7 years of tree age orchards, followed by Ikaika (333) and Hinde (H2), while Keaau (660) and Kakea (508) The average yield of the first seven years was Kau (344), Ikaika (333), followed by Own Choice, while Mauka (741), Makai (800) and Kakea (508) were poor. The output of H2, Own Choice, 333 was significantly higher than that of other varieties, but the difference of 246,508,344,800 was not significant. The quality of products of 9 varieties in South Asia reached the main producing areas in foreign countries Standard.
