The discovery of the endocannabinoid system has raised public interest in the medicinal use of cannabis, phytocannabinoids, and synthetic cannabinoids, which has always been closely regulated due to ...their psychotropic effects and potential abuse. The review takes a quick look at the current legal framework in the European Union, which regulates cannabis use and cultivation for medicinal purposes in line with the United Nations Conventions on the production, trade, and use of cannabis, phytocannabinoids, and synthetic cannabinoids. And while the EU legislation precisely defines requirements and marketing authorisation procedures for medicinal products for all EU member states, there is no common regulatory framework for magistral and officinal preparations containing cannabinoids, as they are exempt from marketing authorisation. Instead, their regulation is left to each member state, and it is quite uneven at this point, mainly due to cultural and historical differences between the countries, leading to different access to non-authorised medicinal products. Therefore, to meet great public interest, harmonised approaches on cannabinoid-containing products without marketing authorisation would be welcome to level the playing field in the EU.
Cultivated plants generally are a poor source of dietary selenium (< 0.1 mg/kg wet weight). In this work the influence of sodium selenate on selenium distribution in the chicory (Cichorium intybus ...L.) cultivars ‘Anivip’ and ‘Monivip’ was studied in an aeroponic system in a greenhouse. The plants roots were moistened every fifteen minutes with a Resh nutrient solution with added selenium (10 mg L-1) in the form of sodium selenate. The content of total selenium in chicory roots and leaves was studied after different periods of time and different temperatures of exposure to the selenium enriched nutrient solution. In two separate experiments chicory was treated with selenium enriched nutrient solution for 40 days at 10 °C in the slow growing phase, and for 5, 7 and 10 days at 20 °C in the developmental phase at the beginning of formation of the flower stem. The concentration in leaves increased with time during plant growth, and in Se treated groups was 370 and 139 mg kg-1 in ‘Anivip’ and 460 and 205 mg kg-1 in ‘Monivip’ leaves after 40 and 10 days of exposure, respectively. A smaller increase in selenium content was obtained in roots, namely to 73 and 46 mg kg-1 in ‘Anivip’ roots and to 87 and 46 mg kg-1 in ‘Monivip’ roots after 40 and 10 days of exposure, respectively. All results are expressed on a lyophilised matter basis. In long and short term treatment, the selenium content in ‘Monivip’ cultivar was higher than in ‘Anivip’. No visible toxic effects on the chicory plants were observed.
Gojene rastline so skromen vir selena (<0,1 mg/kg). Raziskovali smo vpliv selenata na privzem selena in njegovo porazdelitev v radiču (Cichorium intybus L.) kultivarjev ‘Anivip’ in ‘Monivip’. Rastline so bile gojene aeroponično v rastlinjaku. Korenine rastlin smo škropili s Reshevo hranilno raztopino, ki je vsebovala 10 mg Se(VI) L-1 v obliki natrijevega selenata, vsakih petnajst minut. Naredili smo dve pilotni študiji. V prvi študiji so bile rastline, ki so ob začetku poskusa imele 6 listov, izpostavljene 40 dni hranilni raztopini, ki je vsebovala Se(VI) pri temperaturi 10 °C, v drugi pa 5, 7 in 10 dni pri temperaturi 20 °C in v razvojni fazi tik pred cvetenjem. Vsebnost Se je bila večja v listih kot v koreninah in je naraščala s časom izpostavljenosti. Masni delež selena v listih kultivarja ‘Anivip’ se je povečal od 55 na 139 mg kg-1 med petim in desetim dnevom izpostavljenosti, v kultivarju ‘Monivip’ pa od 78 na 205 mg kg-1. Vsebnost Se v koreninah je tudi naraščala, vendar so bile razlike med kultivarjema manjše. Pri 40 dnevni izpostavljenosti je bil masni delež Se 370 mg kg-1 v listih in 73 mg kg-1 v koreninah kultivarja ‘Anivip’ ter 460 mg kg-1 v listih in 87 mg kg-1 v koreninah kultivarja ‘Monivip’. Vsi rezultati so izraženi na liofilizirano snov. Tako pri dolgi kot pri kratki izpostavljenosti rastlin hranilni raztopini s selenom je bila vsebnost Se v kultivarju Monivip večja kot pri kultivarju Anivip. Na rastlinah nismo opazili znakov zastrupitve.
Influence of carbon dioxide concentration during compost and casing soil overgrowth, inoculum rate, casing soil depth and mixing on Agaricus blazei fruiting bodies yield was determined. Compost ...composed of chicken manure and wheat straw which is used for commercial button mushrooms cultivation in Slovenia showed to be appropriate for A. blazei fruiting bodies production. Out of the parameters tested in our experiments, casing soil depth and inoculum rate had the biggest positive effect on fruiting bodies production. For A. blazei fruiting bodies production higher rates of inoculum and at least 8.5 kg of commercial casing soil per square meter of compost surface should be used. Higher carbon dioxide concentrations shoved to be beneficial for attaining higher yields of A. blazei fruiting bodies.
Raziskovan je bil vpliv koncentracije ogljikovega dioksida med preraščanjem komposta in krovne prsti (pokrivke), količine glivnega vcepka primešanega kompostu ter količine krovne prsti in mešanje le-te po preraščanju s podgobjem na obrod gob Agaricus blazei. Kompost pripravljen iz kurjega gnoja ter pšenične slame, ki ga izdelujejo ter na območju Slovenije uporabljajo za komercialno gojenje šampinjonov, se je izkazal kot primeren za gojenje gob vrste A. blazei. Med testiranimi parametri gojenja sta na povečanje pridelka vplivali predvsem količina krovne prsti in koncentracija glivnega vcepka vmešanega v kompost. Za uspešno gojenje je potrebno uporabiti vsaj 8,5 kg komercialne krovne prsti na kvadratni meter komposta. Višje koncentracije ogljikovega dioksida in pokrivke pozitivno vplivajo na obrod gob.
