The study of natural essential oils as growth regulators of winter wheat

Abstract

Growth regulators are rather important for obtaining high yields of agricultural crops. Recently, more and more research on biologically active substances has been carried out among natural products, in particular, essential oils of plants. Our study is aimed at the search for winter wheat growth regulators among essential oils. In three-year field small-plot experiments, the growth-regulating activity of anise, fenchel and apricot oils was studied. When we treated the vegetating plants with the water emulsions of the above mentioned oils (dose – 30 g/ha) twice in the tillering and the flag leaf phases, the yield increase of Grom winter wheat variety was 8.6–10.8 %. The quality of seeds also improved: the protein content increased by 0.6-1.1 %, gluten by 1.8-2.7 %.

Toxicological, biological, and biochemical impacts of the egyptian lavender (Lavandula multifida L.) essential oil on two lepidopteran pests

“…EOs are aromatic and volatile substances with an oily consistency, extracted from different parts of the plant such as the leaf, stem, flower, bark and fruit (Ebadollahi et al 2021). They exhibit insecticidal (Abdelaal et al 2021), antifeedant (Valcárcel et al 2021), growth regulator (Dyadiuchenko et al 2020), and repellent (Lee 2018) effects. When judiciously incorporated as a component of a systems-oriented approach that underscores biological and cultural controls, essential oils present a diminished mammalian toxicity profile, minimal issues related to residues, and a reduced propensity for insect resistance in comparison to broad-spectrum insecticides (Raveau et al 2020).…”

“…For this purpose, they are diligently studying them as insecticides (Titouhi et al, 2017), herbicides (Dutra et al, 2020), fungicides (Amini et al, 2016), and acaricides (Ribero et al, 2019). It has also been proved that essential oils affect plant growth and development; that is why in an agrarian sector, they are used as inhibit ors (oils inhibit the germination of potato tubers during storage) (Shukla et al, 2019) and stimulate plant growth (Dyadiuchenko et al, 2020). Seed treatment with thyme essential oil increases the drought resistance of wheat (Ben-Jabeur et al, 2019).…”
