“…Fakhari et al. [ 29 ] found that Lavender EO contained 35.3% linalool and only 13.4% linalyl acetate, followed by lavendulyl acetate, 1,8-cineol, α-terpineol, lavendulol and geranyl acetate. A similar monoterpene such as linalool, linalyl acetate and 1,8-cineole was identified in EC Italian Lavender [ 30 ].…”

“…Previous studies on P effect on secondary metabolites and essential oil production found a variety of responses to increased P application. P increased essential oil production in Cymbopogon nardus , Olearia phlogopappa (Dragar and Menary, 1995), cannabis (Coffman and Gentner, 1977), dragonhead (Said-Al Ahl and Abdou, 2009), and basil (Ichimura et al, 1995). Essential oil content was not affected by P in sage (Rioba et al, 2015) and basil (Ichimura et al, 1995) and by a moderate P application in cannabis (Bernstein et al, 2019b) and was reduced in Olearia phlogopappa (Dragar and Menary, 1995).…”

An increase in THCA and CBDA concentrations as a response to P deficiency are unlikely to be a direct effect of P on the biochemical pathways due to the crucial role of P in cannabinoid biosynthesis (Fellermeier et al, 2001;Flores-Sanches and Verpoorte, 2008;Sarma et al, 2020).…”

Environmental conditions, including the availability of mineral nutrients, affect secondary metabolism in plants. Therefore, growing conditions have significant pharmaceutical and economic importance for Cannabis sativa. Phosphorous is an essential macronutrient that affects central biosynthesis pathways. In this study, we evaluated the hypothesis that P uptake, distribution and availability in the plant affect the biosynthesis of cannabinoids. Two genotypes of medical “drug-type” cannabis plants were grown under five P concentrations of 5, 15, 30, 60, and 90 mg L–1 (ppm) in controlled environmental conditions. The results reveal several dose-dependent effects of P nutrition on the cannabinoid profile of both genotypes, as well as on the ionome and plant functional physiology, thus supporting the hypothesis: (i) P concentrations ≤15 mg L–1 were insufficient to support optimal plant function and reduced photosynthesis, transpiration, stomatal conductance and growth; (ii) 30–90 mg L–1 P was within the optimal range for plant development and function, and 30 mg L–1 P was sufficient for producing 80% of the maximum yield; (iii) Ionome: about 80% of the plant P accumulated in the unfertilized inflorescences; (iv) Cannabinoids: P supply higher than 5 mg L–1 reduced Δ9-tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) concentrations in the inflorescences by up to 25%. Cannabinoid concentrations decreased linearly with increasing yield, consistent with a yield dilution effect, but the total cannabinoid content per plant increased with increasing P supply. These results reveal contrasting trends for effects of P supply on cannabinoid concentrations that were highest under <30 mg L–1 P, vs. inflorescence biomass that was highest under 30–90 mg L–1 P. Thus, the P regime should be adjusted to reflect production goals. The results demonstrate the potential of mineral nutrition to regulate cannabinoid metabolism and optimize pharmacological quality.

“…Total plant extract yield and polygodial yield of T. lanceolata declined significantly at the highest level of applied P. Average percentage oil yield also declined with higher levels of P fertilizer in the Tasmanian native Oleariaphlogopappa (22). Oil composition responses to nutritional levels in other species have been varied.…”

Perennial horticulture centre, tasmanian institute of agriculture, university of tasmania, hobart, tasmania, australia ABSTRACT Developing systems for the commercial production of native plant species is required to ensure a sustainable supply of quality material. The aim of this study was to examine the influence of key nutrients on the early establishment of Tasmannia lanceolata for potential plantation production of leaves from which polygodial is extracted. Treatments of N, P and K fertilizers were imposed on a single clone in a pot trial with a factorial design. Levels of all other essential nutrients were kept constant. The highest application level of N (20 mM, 2.32% N in leaves) achieved the highest level of polygodial as a percentage of dry matter. The highest P (2 mM, 0.42% P in leaves) and K (12 mM, 1.73% K in leaves) treatments produced a noticeable decline in total polygodial yield, with mediumlevel treatments of both nutrients producing the highest levels of polygodial. The implications of these findings for the production of commercial quantities of T. lanceolata leaf material are discussed.
