摘要
以夏威夷引进澳洲坚果品种Ikaika(333)为试材,进行其早期生长量、产量、品质和抗风性等研究,结果表明:Ikaika(333)与Kau(344)、Own Choice(O.C)、Makai(800)和Keauhou(246)初期的株高、径围、冠幅生长量指标间差异不显著。Ikaika(333)的初产期产量极显著高于(品比区)或高于(国内主要试种区)品种Kakea(508)、Keauhou(246)、Kau(344)、Makai(800),显著高于(品比区)或低于(国内主要试种区)品种Own Choice。与国外主产区相比,品种Ikaika(333)的平均单株产量接近南非的,低于澳大利亚与美国;但单位面积产量显著高于南非,与澳大利亚的水平基本相同,略低于夏威夷。Ikaika(333)的果仁均重、出仁率和果仁含油率均达到国外主产区夏威夷及澳大利亚的水平。在风力7～11级的情况下,Ikaika(333)的抗风性显著低于品种Own Choice(O.C),显著高于品种Makai(800),与品种Keauhou(246)和Kau(344)间差异不显著。
The growth,yield,kernel quality and wind resistance of Macadamia cv ＇Ikaika（333）＇ introduced from the Hawaii were studied in the earier stage.The result showed that it was no remarkable different between the growth of tree height,stem diameter and canopy diameter of Ikaika（333）and Kau（344）,Own Choice（O.C）,Makai（800）,and Keauhou（246）in its early years.The yield of the young tree of Ikaika（333）was extreme significant higher than that of Kakea（508）、Keauhou（246）、Kau（344）、Makai（800）and significant higher than that of own Choice（O.C）in cultivar comparison trial area,or higher than that of Kakea（508）、Keauhou（246）、Kau（344）、Makai（800）and lower that of own Choice（O.C）in the main Macadamia plant regions in China.Compared with the main grown regions in the world,the yield of Ikaika（333）per tree in China was the similar to that of South Africa and lower than that of Australia and America,the yield per area was obvious higher than that of South Africa,the same as that of Australia and a litter lower than that of Hawaii.Its kernel rate,kernel average weight and oil content were similar to those produced in Australia and Hawaii.Under the condition of 7～11 level wind,its wind resistance was obvious lower than that of own Choice（O.C）,obvious higher than that of Makai（800）and no remarkable difference with that of Keauhou（246）and Kau（344）.
