【摘要】 为筛选云南省保山市山区适宜栽培的甜樱桃品种，丰富当地水果产业结构，以7个南方主栽甜樱桃品种为试验材料，通过观测物候期、测定生长及果实品质指标，结合差异分析、相关性分析及主成分分析进行综合评价。结果表明：花期以布鲁克斯最早、萨米脱最晚（相差约2周），果实成熟期以美早最早、萨米脱最晚（相差约3周）；生长指标中单株产量变异系数最大（42.9%），果实指标中糖酸比变异系数最大（43.0%）；品种与15个性状均呈极显著正相关，果实形态性状与叶片大小关联性密切；生长性状4个主因子、果实品质4个主因子累计解释率分别为83.83%、88.98%，综合排名显示，布鲁克斯生长特性最优、美早果实品质最优。依据综合分析结果，推荐美早、布鲁克斯、双罗为保山市山区西邑乡适宜栽培的甜樱桃品种。更多还原

【Abstract】 To screen out suitable sweet cherry cultivars for cultivation in the mountainous areas of Baoshan City,Yunnan Province, and enrich the local fruit industry structure, a comprehensive evaluation was conducted using 7 major sweet cherry cultivars cultivated in southern China as test materials. The evaluation was carried out by observing phenological periods, determining growth and fruit quality indicators, combined with difference analysis,correlation analysis and principal component analysis. The results showed that ‘Brooks’ had the earliest flowering period and ‘Summit’ had the latest(with a difference of about 2 weeks), while ‘Tieton’ had the earliest fruit ripening period and ‘Summit’ had the latest(with a difference of about 3 weeks). Among the growth indicators, the coefficient of variation of yield per plant was the largest(42.9%), and among the fruit indicators, the coefficient of variation of sugar-acid ratio was the largest(43.0%). There was an extremely significant positive correlation between cultivars and 15 traits, and fruit morphological traits were closely correlated with leaf size. The cumulative explanatory rates of4 main factors for growth traits and 4 main factors for fruit quality were 83.83% and 88.98% respectively. The comprehensive ranking indicated that ‘Brooks’ had the optimal growth characteristics and ‘Tieton’ had the optimal fruit quality. Based on the results of comprehensive analysis, ‘Tieton’, ‘Brooks’ and ‘Shuangluo’ are recommended as suitable sweet cherry cultivars for cultivation in Xiyi Township, the mountainous area of Baoshan City.更多还原
