This data article is referred to the research article entitled The role of ascorbate peroxidase, guaiacol peroxidase, and polysaccharides in cassava (Manihot esculenta Crantz) roots under postharvest physiological deterioration by Uarrota et al. (2015). Food Chemistry 197, Part A, 737-746. The stress duo to PPD of cassava roots leads to the formation of ROS which are extremely harmful and accelerates cassava spoiling. To prevent or alleviate injuries from ROS, plants have evolved antioxidant systems that include non-enzymatic and enzymatic defence systems such as ascorbate peroxidase, guaiacol peroxidase and polysaccharides. In this data article can be found a dataset called "newdata", in RData format, with 60 observations and 06 variables. The first 02 variables (Samples and Cultivars) and the last 04, spectrophotometric data of ascorbate peroxidase, guaiacol peroxidase, tocopherol, total proteins and arcsined data of cassava PPD scoring. For further interpretation and analysis in R software, a report is also provided. Means of all variables and standard deviations are also provided in the Supplementary tables ("data.long3.RData, data.long4.RData and meansEnzymes.RData"), raw data of PPD scoring without transformation (PPDmeans.RData) and days of storage (days.RData) are also provided for data analysis reproducibility in R software.
本数据文章参考了Uarrota等人（2015年）发表的题为《抗坏血酸过氧化物酶、愈创木酚过氧化物酶和多糖在采后生理劣变下木薯（Manihot esculenta Crantz）根中的作用》的研究文章。《食品化学》197卷A部分，第737 - 746页。木薯根采后生理劣变产生的胁迫会导致活性氧的形成，活性氧极具危害性且会加速木薯变质。为了预防或减轻活性氧造成的损伤，植物进化出了抗氧化系统，其中包括非酶促和酶促防御系统，如抗坏血酸过氧化物酶、愈创木酚过氧化物酶和多糖。在本数据文章中可以找到一个名为“newdata”的数据集，格式为RData，有60个观测值和6个变量。前两个变量（样本和品种）以及后四个变量，即抗坏血酸过氧化物酶、愈创木酚过氧化物酶、生育酚、总蛋白的分光光度数据以及木薯采后生理劣变评分的反正弦数据。为了在R软件中进行进一步的解释和分析，还提供了一份报告。补充表格（“data.long3.RData、data.long4.RData和meansEnzymes.RData”）中还提供了所有变量的均值和标准差，还提供了未经转换的采后生理劣变评分原始数据（PPDmeans.RData）和储存天数（days.RData），以便在R软件中进行数据分析的再现性研究。
