摘要

本研究鉴定了对高粱化感作用具有显著耐受性的豌豆品种。选择9个品种,研究3种提取液浓度(1、5和10%)对杂草茎部和根部生物量对种子萌发和胚芽生长的影响。数据方差分析显示,提取物品种、类型和浓度对研究参数有显著影响(p <0.05)。只有提取物类型(根/地上生物量)对种子萌发的影响无统计学意义。从化感抑制指标RI的绝对值来看,不同品种的化感抑制程度分别为-0.30 ~ -0.04、-1.31 ~ -2.96和-0.47 ~ 0.02。利用ge -双图分析结果,表明Pulpudeva和Puldin品种具有较高的化感作用,而Denitsa和Vyatovo品种则较为敏感。Ran I, Mira, Musala和Vechernitsa占据中间位置。培育化感抗性品种是当前杂草控制策略的一个有希望的补充,特别是在有机生产中。

A study on the allelopathic tolerance of garden pea varieties to Sorghum halepense (L.) Pers. extracts
The present research study identified garden pea varieties with pronounced tolerance to the allelopatic action of Sorghum halepense. Nine varieties were selected to study the effects of shoot and root weed biomass, applied in three extract concentrations (1, 5 and 10%), on seed germination and initial germ growth. A variance analysis of data revealed significant influence (p <0.05) of three studied factors (variety, type and concentration of extracts) on the investigated parameters. Statistically insignificant was only the influence of extract type (root/aboveground biomass) on seed germination. Based on absolute values of the allelopathic indicator RI, which determines the degree of allelopathic inhibition in terms of germination, germ length and weight in different varieties, the variation was as follows: from -0.30 to -0.04, from -1.31 to -2.96 and from -0.47 to 0.02. The total effect of allelopathic action of S. halepense on all studied parameters, presented as a GGE-biplot analysis, defined Pulpudeva and Puldin varieties as exhibiting higher tolerance, in contrast to Denitsa and Vyatovo, which were sensitive. Ran I, Mira, Musala and Vechernitsa occupied an intermediate position. Cultivation of allelopathic tolerant varieties is a promising addition to the current weed control strategy, especially in organic production.
