Abstract
Abstract Phenolics are the most widely distributed class of plant secondary metabolites and higher plants are able to produce several thousand different phenolic compounds. It has been reported that phenolics are more resistant to decomposition due to the negative impact on the microorganisms involved. Therefore, it may be hypothesized that the higher content of phenolics in plant tissue may cause slower decomposition rates and potentially higher carbon sequestration in the soil. The primary goal of this study was to evaluate and compare the content of phenolics in seven common macrophytes in the Czech Republic. Aboveground biomass was sampled in June 2016 at seven different localities and phenolics concentrations determined by spectrophotometric methods according to the Folin-Cioacalteau method ranged from 9.02 to 28.39 g kg−1 dry biomass weight (DW). Several plants were also harvested in August, October and December in order to follow a seasonal pattern. According to the results it seems that surveyed macrophytes vary widely in phenolics concentrations in relation to sampled site, harvesting time, plant species, and plant parts as well.
酚类物质是植物次生代谢产物中分布最广泛的一类,高等植物能够产生数千种不同的酚类化合物。据报道,由于对相关微生物的负面影响,酚类物质更不易分解。因此,可以假设植物组织中酚类物质含量较高可能会导致土壤中分解速度较慢和潜在的碳固存量较高。本研究的主要目的是评估和比较捷克共和国七种常见大型植物中酚类物质的含量。2016年6月,在7个不同的地点采集了地上生物量,根据Folin-Cioacalteau法分光光度法测定的酚类物质浓度为9.02 ~ 28.39 g kg−1干生物量(DW)。为了遵循季节性模式,一些植物也在8月、10月和12月收获。结果表明,所调查的大型植物中酚类物质的含量与取样地点、采收时间、植物种类和植物部位有关。
