“…Auxins play important roles in plant growth and root development. The enhancement of hairy root growth and secondary metabolite concentration observed in this study is similar to the results of previous reports of enhanced growth and natural compound production after exogenous auxin treatments in hairy root cultures of Lippia dulcis 16 , Lobelia inflata 17 , Panax hybrid 18 and S. baicalensis 19 .…”

Brassicaceae (Cruciferae) is one of the 10 most economically important plant families and includes vegetables such as broccoli, brussels sprouts, cabbage, cauliflower, kale, radish and various mustards. Among the cultivated Brassicaceae, broccoli attracted attention after it was discovered that it contains high levels of isothiocyanate sulforaphane. Isothiocyanate sulforaphane, [4-(methylsulfinyl)butyl isothiocyanate], is produced from the breakdown of glucoraphanin, [4-(methylsulfinyl) butyl GSL] and has great potential anticarcinogenic properties. Sulforaphane is the most potent naturally occurring Phase II enzyme inducer and is considered to play an important role in the detoxification of xenobiotic compounds when assimilated with diet 1,2 .Vegetables from the Brassicaceae family are among the most commonly grown vegetables worldwide. The family includes cabbage, broccoli, cauliflower, kale, collards and Brussels sprouts. Brassica vegetables are rich in bioactive compounds, including polyphenols, tocopherols, ascorbic acid, carotenoids and glucosinolates [3][4][5] . Epidemiological data have

“…39 reported that exogenous IAA, IBA, or NAA auxins stimulate hairy roots growth in Nepeta cataria , and IBA at 0.5 mg · L −1 produced the highest levels of growth. Similarly, exogenous IAA or NAA increases biomass and lobeline production in hairy roots of Lobelia inflata 40 . Before our formal experiment was conducted, according to results from Guizhou Agriculture College and Jiangxi Forestry Institute Leaf Cutting Study Groups of Chinese fir 41, 42 , an L 16 (4) 4 orthogonal test design was carried out with auxin concentrations of 6-BA, NAA, and IBA at 0 mg · L −1 , 50 mg · L −1 , 100 mg · L −1 and 150 mg · L −1 .…”

In order to ascertain the optimal hormone combination for Chinese fir (Cunninghamia lanceolata) leaf cuttings, an L16(4)4 orthogonal test of 6-benzylaminopurine (6-BA), 1-naphthaleneacetic acid (NAA), and indole-3-butyric acid (IBA) (0, 10, 30, or 50 mg · L−1 of each exogenous hormone) immersion for 5, 10, 15, or 20 min was conducted. Callus initiation rate and rooting promotion rate were mainly affected by treatment time, root length increase by 6-BA concentration, and bud germination rate and plantlet formation rate by NAA concentration. The expected optimal combination for callus initiation rate was 50 mg · L−1 6-BA + 0 mg · L−1 NAA + 30 mg · L−1 IBA + 10 min; for rooting promotion rate, it was 0–10 mg · L−1 6-BA + 10 mg · L−1 NAA + 30 mg · L−1 IBA + 20 min; for bud germination rate, it was 50 mg · L−1 6-BA + 0–10 mg · L−1 NAA + 0–30 mg · L−1 IBA + 20 min; and for seedling formation rate for No. 4, it was 10 mg · L−1 6-BA + 10 mg · L−1 NAA + 0 mg · L−1 IBA + 20 min. Light microscopy image analysis revealed that a cluster of primordial cells was produced 40 days after cutting, and mastoid cells developed into peninsula cells in calli that were cultured for 50 days.

“…The type and working concentration of PGRs in the liquids applied depend on the plant species, the tissue or organ cultured, and the objective. These substances can influence plant physiology to change morphological (i.e., root biomass and architecture) and metabolic properties [2,3]. The commonly used PGRs are auxins, cytokinins, and gibberellins; some PGRs have as active ingredients biologically active substances synthesized by microorganisms, including fungi, such as micromycetes [3] or species of the genus Cylindrocarpon obtusiusculum Sacc.…”

Impact of Plant Growth Regulators to Development of the Second Generation Energy Crop Miscanthus × giganteus Produced Two Years in Marginal Post-Military Soil

et al. 2022

The impact of the plant growth regulators (PGRs) Stimpo, Regoplant, and Charkor on the production of the second-generation energy crop Miscanthus × giganteus on marginal post-military soil was investigated during two vegetation seasons. The land, previously a tank training polygon, has not been in use since 1990 and has become marginal. Biological parameters (stem, shoot, and root lengths) and dry biomass values were evaluated in relation to the applied treatments. The multivariate general linear model (M-GLM) results showed a positive influence of Charkor on M. × giganteus development; the effect was markedly higher in the second year of vegetation. The impact of Stimpo and Regoplant was less noticeable; nevertheless, certain combinations of treatments showed satisfactory results. The M-GLM approach detected the inter-influence of the main factors of the production process, i.e., PGRs, soil, and year of growing. The results showed the predominant influence of year, PGRs and combined factor PGRs × year on the biological parameters; the other studied factors and their combinations were not as effective. Further research should focus on verifying the field-scale results for the M. × giganteus plantation established in a post-military area and compare the lab and field studies.
