New Trends of Gentiana Lutea Cultivation Gentiana Lutea L.

Hot Spots of Bitter Compounds in the Roots of Gentiana lutea L. subsp. aurantiaca: Wild and Cultivated Comparative

“…Even though the analysis of full root systems from cultivated gentian has shown a higher concentration of amarogentin in younger plants [40], our results suggest that the age of the plant is not the only factor influencing the concentration of amarogentin. Rather, the root system development and thus the share of the different tissues is a decisive factor.…”

“…In the analysis of cultivated gentian, it is possible to compare plants with the same age [38] or similar weight [39] but the root structure is typically highly variable. For comparing cultivated and wild gentian, analysing roots with similar diameters as completed by Barralis et al [40] is one of the most suitable approaches, although the age of wild gentian remains unknown.…”

Cultivation trials on Gentiana lutea L. in Southern and South-eastern Europe

“…lutea plantations are mainly established with a use of nursery plants, for whose production several methods were developed. Various authors (Barralis et al, 1986(Barralis et al, , 1978Franz and Fritz, 1978;Fritz et al, 1980) reported three methods, briefly explained in the text that follows. According to the first method, the water-soaked gentian seeds were mixed with the peat and left for 2 months at a temperature of about 2 • C. About 3 seeds are to be sown per one paper pot stuffed with substrate, which have to be left in controlled environment until the end of spring, until sprouting and initial seedlings growth complete.…”

“…Gentian can be also planted in double rows, 20-25 cm apart from each other, while the distance of plants in rows should be 15-20 cm; thus planting density of about 100,000 plants per ha it could be achieved (Barralis et al, 1986(Barralis et al, , 1978Franz, 2012). Cultivation trials in Italy were carried out with planting density of 40,000 (Barbaro et al, 2009), of 95,000 (Menghini et al, 1996) and of 100,000-71,400 or 99,000-107,000 plants per ha (Aiello and Bezzi, 1989;Bezzi and Aiello, 1993;Bezzi et al, 1997Bezzi et al, , 1996Bezzi et al, , 1986, while in Serbia, the distance between the rows was set to 70 cm (due to the most common machinery used for inter-row processing), and the distance in the rows was set to 20-30 cm, thus achieving a planting density of 47,000-71,000 plants per ha .…”

Herbicides for Gentians

“…However, there are few publications about the use of herbicides on this crop. Batt (1982) indicated that simazine was safe on gentian crops and Barralis et al (1978) found two amide herbicides (propachlor and diphenamid) to be safe on G. lutea. In a preliminary trial (Ingle unpublished) several herbicides (e.g.…”
