The successful production of maize is fundamentally determined by a good choice of tillage type. Options include conventional tillage based on soil rotation, as well as a more recent conservation approach. Our aims were to determine the stress physiological effects of the plant remains left behind by different tillage procedures on the juvenile maize plants, combined with the effects of fungicide treatment on the seeds. These effects were followed and investigated by means of biophoton emission measurement, an in vivo and non-invasive imaging technique, along with chlorophyll content estimation, as well as microbial- and polymerase chain reaction-based identification of fungi presence. Our results confirmed the response reactions of maize triggered by a soil covering plant remains on the initial development and physiological involvement of maize. The positive effects of seed treatment on initial development are manifested only at the final stage of the experiment. The fungal microbiological analysis confirmed the dominant presence of necrotrophic parasites on plant residues, the stress-inducing properties of which were possible to monitor by biophoton emission. Furthermore, the presence of spp. was confirmed by PCR analysis from samples treated with plant residues.
玉米的成功生产从根本上取决于对耕作类型的良好选择。选择包括基于轮作的传统耕作，以及一种更新的保护性耕作方法。我们的目的是确定不同耕作程序留下的植物残体对玉米幼苗的胁迫生理影响，以及杀菌剂处理种子的影响。通过生物光子发射测量（一种体内非侵入性成像技术）、叶绿素含量估计以及基于微生物和聚合酶链反应的真菌存在鉴定来跟踪和研究这些影响。我们的结果证实了土壤覆盖植物残体对玉米初始发育和生理参与所引发的玉米反应。种子处理对初始发育的积极影响仅在实验的最后阶段显现。真菌微生物分析证实了植物残体上坏死营养型寄生虫的优势存在，其胁迫诱导特性可通过生物光子发射进行监测。此外，通过对用植物残体处理的样品进行PCR分析，证实了 spp. 的存在。
