| 中文摘要: |
| 以Coolidge、Unique、Mammoth、Gemini和Triumph等5个费约果品种为材料，探究不同费约果品种对产量方面的差异，结果表明，5个费约果品种在树体生长情况上均有所不同，其中，叶面积指数、树冠体积在品种间存在显著差异（P<0.05），Mammoth叶面指数最大，Coolidge树冠体积最大；不同品种在花序数、开花数及单个花序开花数均存在显著差异，Triumph花序数最多为58.33，Unique开花数最多为986.33，Gemini单个花序的开花数最多为26.37；在不同费约果品种的新梢及结果枝长短组成比较中，5个费约果品种的中梢及长果枝（Gemini除外）均为主要组成部分；在不同费约果结果特性研究中，5种费约果的结果数、坐果率及单株产量上存在显著差异，其中，Unique结果数最大为489.67，Gemini坐果率最高为60.91%，是Mammoth的2.1倍，Unique单株产量最高为12455.01g，是Mammoth的3.67倍。在果实单果重上，不同品种间没有显著差异，其中，Coolidge单果重最高为25.85g。进一步研究，得出费约果的开花数与单果重呈现负相关，与单株产量呈现显著性正相关(p<0.05)。综合而言，Unique生长情况较好，坐果率仅低于Gemini，且开花数及单株产量显著高于其他四个品种。因此，Unique为绵阳地区的高产品种，具有推广价值。 |

| We studied five varieties to explore the yield differences among varieties of feijoa, including Coolidge、Unique、Mammoth、Gemini and Triumph. The result show that: the growth of every variety of fruit are different. Leaf area index and tree crown volume are significantly different among the five varieties(p<0.05),the lagrest Leaf area index is Mammoth,the lagrest crown volume is Coolidge; The inflorescences number, flowers number and single inflorescence flowers number are significantly diferencet among the five varieties. The inflorescences number of Triumph ,the flowers number of Unique,and the single inflorescence flowers number of Gemini is the lagrest,reaching to 58.33, 986.33, 26.37 respectively; Medium shoot and long fruit shoot are the main components in all varieties of feijoa except Gemini;The number of fruit, fruit rate and per plant yield are also significantly diferenct among the five varieties, the lagrest number of fruit is Unique,reaching to 489.67,the highest fruit rate is Gemini,up to 60.91%,about 2.1 times of Mammoth,the top per plant yield is Unique,up to 12455.01g ,about 3.67 times of Mammoth. There was no significant difference on the weight of single fruit among the five varieties,and Coolidge have the heaviest single fruit,about 25.85g. Further results indicated that The number of flowers was negatively correlated with the weight of single fruit, was positively correlated with the yield per plant(p<0.05). Overall, the growth of Unique is preferable,the fruit rate is the second highest next only to Gemini ,the flowers number and the yield per plant are significantly higher than other four varieties of feijoa.Therefore, Unique is high-yielding varieties around Mianyang area,and has great popularization value. |
