“…It could be concluded that hydrolates of this plant can be used as biological herbicide with T. aestivum and R. sativus. Furthermore, hydrosoluble compounds can improve the possibilities of applying them as bioherbicides in the future [84]. The effects of different concentrations of Ocimum basilicum hydrolate on germination rate and shoot and root length of O. basilicum and Chenopodium quinoa seeds have been investigated, too.…”

Hydrolates, also referred to as hydrosols, floral or distillate waters, as well as aromatic waters, are produced in the same isolation process with essential oils by steam distillation. A small amount of essential oil constituents is dissolved in hydrolates providing specific organoleptic properties and flavor, as well as biological activity which makes them useful as raw material in many industries. Their popularity is still on the rise, especially in aromatherapy. The objective in this review is to analyze the chemical compositions of hydrolates and their corresponding essential oils, as well as biological activity of hydrolates (antimicrobial, antioxidant and antiinflamatory) and potential uses, not only in food industry for flavoring, and preservation of fresh-cut fruits and vegetables, but also as functional (soft) drinks. However, hydrolates can be used in aromatherapy and cosmetics, as well as in organic agriculture and aquaculture.

“…This is most likely due to the high content of essential oils in the medicinal plants species [10]. Essential oils, which primarily are a mixture of VOCs have been studied for their weed control potential [11]. However, individual constituents of VOCs have been less studied for their potentials in alternative weed management strategies.…”

Evaluation of Biological Response of Lettuce (Lactuca sativa L.) and Weeds to Safranal Allelochemical of Saffron (Crocus sativus) by Using Static Exposure Method

et al. 2019

Safranal, the main volatile chemical of Saffron (Crocus sativus) was studied to estimate its allelopathic effects on the photosynthetic pigment chlorophyll, leaf electrolyte leakage, fresh weight, catalase (CAT), and peroxidase (POX) activity of the test plant Lettuce (Lactuca sativa). In this study, the effective concentration (EC50) of safranal on CAT was estimated to be 6.12 µg/cm3. CAT activity was inhibited in a dose-dependent manner by the increase in the safranal concentration while POX activity was increased. Moreover, Safranal caused significant physiological changes in chlorophyll content, leaf electrolyte leakage, and fresh weight of several weed species with Lolium multiflorum being the most sensitive. Furthermore, 5 µM Safranal showed significant inhibitory activity against dicotyledonous in comparison to the monocotyledons under greenhouse conditions. The inhibition of the CAT by safranal was similar to those of uncompetitive inhibitors, and therefore the decline in carbon fixation by plants might be the mechanism behind the inhibitory activity of safranal.

“…However, maximum inhibition was observed in case of Z. mays for both radicle and plumule length. This observation is not new as there are several reports in literature which indicate the growth retardatory effects of essential oils and their chemical constituents, especially the monoterpenes [8,15,20,21,22]. [23] assessed the activity of twenty seven monoterpenes against seed germination and early radicle growth of Raphanus sativus L. (radish) and Lepidium sativum L. (garden cress).…”

“…Release of essential oils and their constituent monoterpenes from aromatic plants affects the growth of other plants in their vicinity. There are a number of reports which highlight the importance of these essential oils as allelopathic agents [10,11,12,13,14,15]. In view of the above studies, it is worthwhile to assess the phytotoxicity of other monoterpenoids/constituents of essential oils so as to identify potential lead chemicals for synthesis of new herbicides.…”

The present study was conducted to evaluate the phytotoxic effect of eugenol, a monoterpenoid alcohol, on some crop species and to determine its anatomical implications. For this study, three crops viz., Zea mays, Phaseolus aureus and Oryza sativa were selected. A laboratory bioassay was carried out to assess the phytotoxicity of eugenol on the crop species in a dose-dependent manner. Eugenol inhibited the early growth of the crop species determined by its effect on the radicle and plumule length. The radicle and plumule length were found to decrease with increase in concentration of eugenol in all the three crop species. Significant inhibition was observed at higher dose of eugenol treatment. The radicle inhibition was more pronounced as compared to the plumule. Zea mays was found to be the most sensitive among the test plants. Further, significant alterations in the internal structure of roots of Zea mays as seen in the epidermal, cortical and vascular regions were observed due to eugenol treatment. Therefore, the phytotoxicity of eugenol towards crops is a significant step to determine its potential against weed species for its possible use as a bio-herbicide in the agro-ecosystems.
