摘要：[目的]分析云南保山‘次郎’甜柿果实主要矿质元素与果实品质关系,筛选影响不同果实品质的主要矿质元素,为南方甜柿园精准施肥提供科学依据。[方法]利用相关分析和通径分析方法,分析云南保山19个柿园‘次郎’甜柿果实9种矿质营养元素与6种果实品质指标间的相关性和通径系数。[结果]表明:甜柿果实单果质量与果实氮、钙、镁元素含量极显著负相关,果实硬度与果实钙元素含量显著正相关,可溶性固形物与果实氮、钙、铜、锌元素含量极显著负相关。通径分析结果,氮、钙元素对单果质量的直接负作用达到显著水平,直接通径系数为-0.4200、-0.3860;钙元素对果实硬度的直接正作用最大,直接通径系数为0.3630,对果形指数的直接负作用最大,直接通径系数为-0.4050;可溶性固形物受钙和氮元素的显著直接负作用影响,直接通径系数分别为-0.6670、-0.3670;维生素C含量受磷元素显著直接负作用影响,直接通径系数为-0.4950,受果实钙、钾元素直接正作用影响,直接通径系数分别为0.4280、0.3940;类胡萝卜素含量受果实钾元素极显著直接负作用影响,直接通径系数为-0.7770,受氮、磷、锰元素显著直接正作用影响,直接通径系数分别为0.4520、0.4210、0.3920。[结论]甜柿果实氮、磷、钾、钙元素与果实品质关系密切,其中磷、钾元素与果实维生素C、类胡萝卜素含量关系密切,而氮元素对单果质量及可溶性固形物存在直接负作用。钙元素与单果质量、果形指数、可溶性固形物、维生素C、果实硬度均密切相关。云南保山柿园甜柿生产中,需降低氮肥施用,科学协调磷、钾、钙肥施用,以实现甜柿的优质高效生产。
[Objective] To investigate the relationship between mineral elements contents and fruit quality of Diospyros kaki Thunb. ‘Jiro’ fruit. [Method] The correlation and path coefficient of nine mineral elements and six fruit quality indexes were analyzed on nineteen D. kaki Thunb. ‘Jiro’ orchards in Baoshan City, Yunnan Province.[Result] The fruit weight was extremely significant and positively correlated with the N, Ca and Mg contents. The fruit firmness was significantly and positively correlated with the Ca content, the soluble solids was significantly and negatively correlated with the N, Ca, Cu and Zn contents. Path analysis further demonstrated that the N and Ca contents had the significantly direct-negative effect on fruit weight(path coefficient-0.420 0 and-0.386 0). The Ca content had the greatest direct-positive effect on the firmness(0.363 0), and the greatest direct-negative effect on fruit shade index(-0.405 0). The soluble solid content was significantly and direct-negatively affected by the Ca and N contents(-0.667 0 and-0.367 0). Vitamin C content was significantly and direct-negatively affected by the P content(-0.495 0), direct-positively affected by the Ca and K contents(0.428 0 and 0.394 0). The carotenoid content was extremely significant and direct-negatively affected by the K content(-0.777 0), significantly and direct-positively affected by the N, P and Mn contents(0.452 0, 0.421 0 and 0.392 0). [Conclusion] The N, P, K and Ca contents of persimmon fruits are closely related to fruit quality. The P and K are significantly related to Vitamin C and Carotenoid contents. The N had direct-negative effect on the fruit weight and soluble solid content. Calcium is significantly related to fruit weight, fruit shape index, Vitamin C content, soluble solid content and fruit firmness. Reducing N application and rationalizing the proportion of P, K, Ca nutrient elements will benefit the high quality D. kaki Thunb.‘Jiro’ production in Baoshan City, Yunnan Province.
