Abstract

Common environmental stimuli detected by living things include light, temperature and a variety of chemical signals some of which are closely related to physical-mechanical stimuli. Sound is one of the physical signals affecting plant life and the mechanism whereby plants perceive and react to sound stimuli is not currently well known. Sound waves and therefore sonication, are a form of abiotic stress for plants. Mint (Mentha piperita) is an important crop that produces volatile oils which are used extensively in pharmaceutical and nutraceutical products. Mint plants (10-week-old) cv. Granada was planted in four different sound chambers and subjected to different sound conditions. The experiment was carried out for 30 days. In each chamber, spe- cific sound areas were formed by sending signals with different dB levels (95, 100 and 105 decibel (db)) together with the chosen reference value was 1000 Hertz (Hz). Plant height, stem diameter, number of leaves, fresh and dry root weights and fresh and dry foliage weights were examined to evaluate the effects of different applications. In addition to the morphological data, the plant nutrient elements and essential oil yields were analyzed. Based on the results, plant height varied between 20 and 43 cm and the essential oil yield ranged between 0.76 and 2.17 %. In our study, sound applications at different SPLs affected the growth and nutrient element intake in mint plants negatively; however, at 95 dB, essential oil yields were affected positively.

摘要

生物检测到的常见环境刺激包括光，温度和各种化学信号，其中一些与物理机械刺激密切相关。声音是影响植物生命的物理信号之一，而植物感知和响应声音刺激的机制目前尚不为人所知。声波和声波处理是植物非生物胁迫的一种形式。薄荷（薄荷））是一种重要的农作物，其产生的挥发油被广泛用于医药和营养产品。薄荷植物（10周龄）。格拉纳达被种植在四个不同的音室中，并经受着不同的声音条件。实验进行了30天。在每个室内，通过发送具有不同dB级别（95、100和105分贝（db））的信号以及选定的参考值为1000赫兹（Hz）来形成特定的声音区域。检查植物高度，茎直径，叶数，鲜重和干燥根重以及鲜重和干燥叶重，以评估不同应用的效果。除形态数据外，还分析了植物营养元素和精油产量。根据结果​​，株高在20至43厘米之间变化，精油产率在0.76至2.17％之间。在我们的研究中，不同声压级的合理应用对薄荷植物的生长和营养元素的摄入有负面影响。但是，在95 dB时，精油产量受到积极影响。
