摘要：

为深入探究认证情况与种植区域对江苏省粳稻品质的影响，本研究选取绿色认证及常规种植的南粳46和南粳9108为试验材料，在苏南、苏中、苏北水稻主产区采集样本，以稻米外观、蒸煮食味及营养品质指标为主要评价依据，运用主成分分析（PCA）方法评估绿色认证稻米品质特征。结果表明，绿色认证南粳46和南粳9108蛋白质含量较常规种植分别显著下降14.5%和6.1%。种植区域极显著影响粳稻直链淀粉含量。其中，苏南种植的南粳46直链淀粉含量较苏中种植提高12.9%；苏中种植的南粳9108直链淀粉含量较在苏北种植提高7.6%（P<0.01）。绿色认证、不同种植区域以及不同粳稻品种对稻米氨基酸与有益矿物质含量均无显著影响。主成分分析结果揭示了绿色认证粳稻品质具有区域特异性。与常规种植相比，苏南种植区域绿色认证的南粳46蛋白质含量降低20.7%，食味值提高16.0%；苏中种植区绿色认证的南粳9108垩白度降低13.5%。本研究结果可为绿色稻米产业高品质发展提供参考依据。

Abstract:

To thoroughly investigate the effects of certification status and planting regions on the quality of japonica rice in Jiangsu Province, this study selected Nangeng 46 and Nangeng 9108, which were cultivated under both green certification and conventional planting methods, as the research objects. Samples were collected from the rice-growing regions of Southern Jiangsu, Central Jiangsu, and Northern Jiangsu, respectively. The principal component analysis method was employed to assess and evaluate the appearance quality, cooking and eating quality, as well as nutritional quality of the rice. The research results indicated that the protein content of green-certified Nangeng 46 and Nangeng 9108 decreased by 14.5% and 6.1% compared with that of rice grown under conventional methods, respectively. The planting region had a highly significant impact on the amylose content of japonica rice. For instance, the amylose content of Nangeng 46 planted in Southern Jiangsu increased by 12.9% compared with that in Central Jiangsu; the amylose content of Nangeng 9108 planted in Central Jiangsu increased by 7.6% compared with that in Northern Jiangsu(P<0.01). In terms of amino acid and beneficial mineral content, there were no significant differences among certification status, planting regions, and rice varieties. The results of the principal component analysis showed that the quality of green-certified japonica rice had stronger regional specificity. In Southern Jiangsu, the protein content of green-certified Nangeng 46 decreased by 20.7% compared with Nangeng 46 grown under conventional methods, but its taste value increased by 16.0%; in central Jiangsu, the chalkiness degree of green-certified Nangeng 9108 decreased by 13.5% compared with Nangeng 9108 grown under conventional methods. The findings of this study provide valuable reference for the high- quality development of the green rice industry.
