Integrated wheat management strategies can affect grain yield and flour end-use properties. However, the effect of integrated management and its interaction with environmental factors on the phenolic acid profiles of wheat has not been reported. The phenolic acid profile has become another parameter for the evaluation of wheat quality due to its potential health benefits.
Year × location × management and year × management × genotype interactions were significant for the total phenolic content (TPC) of wheat samples. The year × location × management × genotype interaction was significant for the concentration of trans-ferulic acid and several other phenolic acids. Field management practices with no fungicide application (e.g., farmer's practice, enhanced fertility) may lead to increased accumulation of phenolic compounds, especially for WB4458, which is more susceptible to fungi infection. However, this effect was also related to growing year and location. Higher soil nitrogen content at sowing also seems to affect the TPC and phenolic acid concentration positively.
Wheat phenolic acid profiles are affected by genotype, field management, environment, and their interactions. Intensified field management, in particular, may lead to decreased concentration of wheat phytochemicals. The level of naturally occurring nitrogen in the soil may also affect the accumulation of wheat phytochemicals. © 2021 Society of Chemical Industry.
综合小麦管理策略会影响谷物产量和面粉的最终使用特性。然而，综合管理及其与环境因素的相互作用对小麦酚酸谱的影响尚未见报道。由于其潜在的健康益处，酚酸谱已成为评估小麦品质的另一个参数。
年份×地点×管理以及年份×管理×基因型的相互作用对小麦样品的总酚含量（TPC）具有显著影响。年份×地点×管理×基因型的相互作用对反式阿魏酸和其他几种酚酸的浓度具有显著影响。不使用杀菌剂的田间管理措施（例如农民的做法、提高肥力）可能会导致酚类化合物积累增加，尤其是对于更易受真菌感染的WB4458而言。然而，这种影响也与种植年份和地点有关。播种时较高的土壤氮含量似乎也对总酚含量和酚酸浓度有积极影响。
