摘要
在尼泊尔 Chitwan 的 Bharatpur-5 进行了一项试验,以评估草莓的质量参数,从而筛选出有前景的高价值品种。试验由八个品种 "佛罗里达美人、佛罗里达节日、甜美感觉、红宝石宝石、伊利亚娜、冬星、冬拂晓和 Nyho(对照品种)"作为处理,采用单因子 RCBD,四次重复。不同品种的果实在各自的生理成熟期采收,提取新鲜果汁进行定性分析。定性分析结果表明,Nyho 品种的 TSS 最高(9.88 °Brix),而 Florida Festival 品种的 TSS 最低(6.58 °Brix)。Elyana 果实的 TA 值最高(0.93 %),维生素 C 含量最高(75.57 毫克/100 克),而 Sweet Sensation 果实的 TA 值最低(0.71 %),Nyho 果实的维生素 C 含量最低(59.89 毫克/100 克)。在草莓品种的抗氧化性方面,Elyana 的抗氧化性较好(81.33%),而 Nyho 的抗氧化性最低(63.23%)。Nyho 果实中的酚含量最高(0.64 毫克 GAE/克),而 Winter Star 果实中的酚含量最低(0.24 毫克 GAE/克)。在测试品种中,Nyho 的甜度和香气最高,而 Elyana 和 Sweet Sensation 在营养属性方面更胜一筹。
Evaluation of Chemical Attributes of Low Chilling Strawberry (Fragraria ananassa) Varieties in Chitwan, Nepal
An experiment to evaluate the qualitative parameters of strawberries to select the promising and high-value varieties was conducted in Bharatpur-5, Chitwan Nepal. The experiment comprises eight varieties ‘Florida Beauty, Florida Festival, Sweet Sensation, Ruby Gem, Elyana, Winter Star, Winter Dawn, and Nyho (check variety) as treatments, laid out in a single factorial RCBD with four replications. The fruits of different varieties were harvested at their respective physiological maturity and fresh juice was extracted for qualitative analysis. The qualitative analyses revealed that the maximum TSS (9.88 °Brix) was recorded in the Nyho variety while the minimum TSS (6.58 °Brix) was recorded in Florida Festival. The maximum amount of TA (0.93 %) and the highest Vitamin C (75.57 mg/100 g) was recorded in fruits of Elyana while the minimum TA (0.71 %) in Sweet Sensation and the lowest amount of Vitamin C (59.89 mg/100 g) was recorded in Nyho. In the case of antioxidant properties of evaluated strawberry varieties, Elyana was found to be superior (81.33 %) while the lowest antioxidant properties were observed in fruits of variety Nyho with a value of 63.23 %. The maximum phenols content (0.64 mg GAE/g) was found on harvested fruits of Nyho while the minimum phenols content (0.24 mg GAE/g) was recorded in fruits of the Winter Star variety. Among the tested varieties, sweetness and aroma were the highest in Nyho while Elyana and Sweet Sensation were superior in nutritional attributes.
