Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The main goal of this study was to develop an efficient micropropagation protocol for cannabis (Cannabis sativa L.) and to summarize the influence of plant growth regulators on cannabinoid production in various in vitro cultures. Three in vitro culture lines were obtained during cannabis micropropagation and referred to calli, shoots, and plantlets. Shoot multiplication was examined on apical segments isolated from in vitro seedlings and cultivated on solid MS/B medium supplemented with various concentrations (0.05-1.0 mg·L) of thidiazuron (TDZ). Callogenesis was induced from leaf explants of seedlings in the presence of 1.0 mg·L TDZ and 0.5 mg·L 1-naphthaleneacetic acid (NAA), while further biomass production was evaluated upon TDZ (0.5-2.0 mg·L). The shoot regenerative potential was assessed on various concentrations (0.1-1.0 mg·L) of indole-3-butyric acid (IBA). The HPLC-DAD analysis of cannabinoids revealed that cannabidiolic acid (CBDA), cannabidiol (CBD), cannabinol (CBN), ∆-tetrahydrocannabinol (∆-THC), and ∆-tetrahydrocannabinolic acid (∆-THCA) were the main identified cannabinoids in calli, shoots and regenerated plantlets. The superior production of Δ-THC was observed in multiple shoots cultured on 0.05 mg·L TDZ (49.23 mg·g), callus cultures treated with 1.0 mg·L TDZ (3.92 µg·g), as well in plantlets regenerated on hormone-free medium (80.1 mg·g). The Δ-THC content in the leaves of 6-month-old regenerated plantlets was significantly higher (1.6-fold) than that of the mother plant. Cannabinoid contents in the inflorescences of the mother plant were higher or even comparable to those observed for acclimatized plantlets. In conclusion, cannabis in vitro cultures could be proposed as promising systems for cannabinoid production.
