“…Electronic nose sensors do not require chemical reagents, have good sensitivity and specificity, provide rapid repeatable (precise) results, and allow non-destructive sampling of gas odorants or analytes [388]. Furthermore, e-noses generally are far less expensive than analytical systems, easier and cheaper to operate, and have greater potential for portability and field use compared with complex analytical laboratory instruments [90].…”

Electronic-nose (e-nose) instruments, derived from numerous types of aroma-sensor technologies, have been developed for a diversity of applications in the broad fields of agriculture and forestry. Recent advances in e-nose technologies within the plant sciences, including improvements in gas-sensor designs, innovations in data analysis and pattern-recognition algorithms, and progress in material science and systems integration methods, have led to significant benefits to both industries. Electronic noses have been used in a variety of commercial agricultural-related industries, including the agricultural sectors of agronomy, biochemical processing, botany, cell culture, plant cultivar selections, environmental monitoring, horticulture, pesticide detection, plant physiology and pathology. Applications in forestry include uses in chemotaxonomy, log tracking, wood and paper processing, forest management, forest health protection, and waste management. These aroma-detection applications have improved plant-based product attributes, quality, uniformity, and consistency in ways that have increased the efficiency and effectiveness of production and manufacturing processes. This paper provides a comprehensive review and summary of a broad range of electronic-nose technologies and applications, developed specifically for the agriculture and forestry industries over the past thirty years, which have offered solutions that have greatly improved worldwide agricultural and agroforestry production systems.

“…It is noticeable, in this PCA plot, that the high dispersion of the lampante oil data (already detected in the membership grade functions generated by the fuzzy filtering) may prevents a reliable classification. In order to overcome this inconvenience, artificial neural network was used as it is suitable to deal with complex data and it has proven to be useful when analysing sensor responses in classification and regres- sions tasks [3]. A multilayer perceptron (MLP), considered as one of the most common artificial neural network architectures, was designed to distinguish lampante and non-lampante VOOs.…”

“…Including well-designed electrophysiological and behavioural bioassays can provide essential additional information about bioactive compounds that cannot or can barely be detected in chemical analyses. In future studies biosensing techniques including electronic noses [203][204][205][206] might add to classical chemical analyses of…”

The relatively new research field of Chemical Ecology has, over the last two decades, revealed an important role of plant-produced volatile organic compounds (VOCs) in mediating interactions between plants and other organisms. Of particular interest are the volatile blends that plants actively emit in response to herbivore damage. Various efforts are underway to pinpoint the bioactive compounds in these complex blends, but this has proven to be exceedingly difficult. Here we give a short overview on the role of herbivore-induced plant volatiles in interactions between plants and other organisms and we review methods that are currently employed to collect and identify key volatile compounds mediating these interactions. Our perspective on future directions of this fascinating research field places special emphasis on the need for an interdisciplinary approach. Joint efforts by chemists and biologists should not only facilitate the elucidation of crucial compounds, but can also be expected to lead to an exploitation of this knowledge, whereby ecological interactions may be chemically manipulated in order to protect crops and the environment.
