Abstract

Navadna konoplja (Cannabis sativa L.) je enoletna dvodomna rastlina, zaradi večjih pridelkov in enakomernega dozorevanja pa se žlahtnjenje usmerja v vzgojo enodomnih sort. Pomembno je poznavanje razlik med industrijsko in indijsko (medicinsko) konopljo, ki ju uvrščamo v isto botanično vrsto. Med številnimi zdravilnimi učinkovinami, ki se oblikujejo v smolnih žleznih trihomih ženskih socvetij, so številni kanabinoidi, tudi najbolj znana kanabinoida delta-9-tetrahidrokanabinol (Δ9THC) in kanabidiol (CBD). Poznamo več kemotipov konoplje, ki se razlikujejo po deležu kanabinoidov. Poleg sorte vplivajo na vsebnost kanabinoidov tudi rastne razmere, starost in del rastline, čas žetve in način spravila. Vsebnost kanabinoidov je ponavadi večja, če so rastline izpostavljene stresu. Na povečano tvorbo kanabinoidov vplivajo sušne razmere in vsebnost hranil, še posebej dušika v tleh. Temperatura vpliva na vsebnost kanabinoidov posredno, saj vpliva na vlažnost tal. Ob močnih padavinah se tvori manj kanabinoidov. Na cvetenje in vsebnost kanabinoidov vplivata tudi dolžina osvetlitve in spekter svetlobe. Raziskovalci menijo, da lahko s preučevanjem vpliva rastnih razmer na vsebnost kanabinoidov v prihodnje dobimo rezultate, s pomočjo katerih bo večji pridelek za medicino pomembnih smol, v kateri so poleg kanabinoidov tudi terpeni in številne fenolne snovi.

Secondary title: Influence of growth conditions on cannabinoid content in hemp (Cannabis sativa L.) with emphasis on CBD and THC
Secondary abstract: Hemp (Cannabis sativa L.) is an annual dioecious plant. Today, breeding of monoecious varieties is common due to higher yields and uniform ripening. It is important to know the differences between industrial hemp and medicinal cannabis, which are botanically classified as the same species. Among many active substances that are formed in the glandular trichomes of female inflorescences there are many cannabinoids, including the most known cannabinoids delta-9-tetrahydrocannabinol (Δ9THC) and cannabidiol (CBD). There are more different chemotypes of hemp which differ in the proportion of cannabinoids. Besides variety, growing conditions, age, part of the plant, harvesting time and method of harvesting also influence the cannabinoid content. Cannabinoid content is generally higher in plants under stress conditions. Increased cannabinoid production is due to drought and nutrient content in the soil, especially to nitrogen content. Temperature affects the cannabinoid content indirectly through soil moisture. In case of heavy precipitation, fewer cannabinoids are formed. The flowering time and consequently the formation of cannabinoids are also influenced by time of exposure to the light and by the light spectrum. Researchers believe that in the future we may obtain the results which can help us increase the yield of medicinally important resins which, besides cannabinoids, contain terpenes and a number of phenolic compounds.
