The influence of mineral fertilizers on seed productivity and quality of obtained seeds of lemon balm (Melissa officinalis L.) was studied in the field small-scale experiment under conditions of unstable moistening of the Mordovia Republic. As a result, it was found that seed productivity varied depending on weather conditions and the types of fertilizers introduced. It was shown that the maximum productivity of Melissa officinalis plants was on the variant with the use of phosphorus-potassium fertilizers at a dose of P60K90 (71.2±78.5 g/m2 in 2017 and 48.8±4.3 g/m2 in 2018), while it exceeded the control variant by 74-91 %. The total germination of seeds of Melissa officinalis practically did not change over the years, and was in the range of 37-39 %. Separation of seeds according to the degree of aging allowed to increase germination 11.4-13.3 %.

The aim of the present study was to investigate the susceptibility of bacteria that play a role in respiratory tract and skin infections to the essential oils of catnip (Nepeta cataria), lemon catnip (N. cataria var. citriodora) and lemon balm (Melissa officinalis) with regard to their chemical composition. In addition, we wanted to assess whether antibiotic-resistant and -sensitive strains differ in their susceptibility to the oils and if there are cross resistances between standard antibiotics and essential oils. To evaluate the safety of topical application, cytotoxicity of the oils was studied in human keratinocyte and bronchial epithelial cell lines and irritation threshold concentrations were determined in ovo using the HET-CAM-test. The composition of the essential oils was analyzed by GC and GC-MS. Their MICs and MBCs were determined by a broth microdilution method against both reference strains from culture collections and clinical isolates with different susceptibility to standard antibiotics. Cytotoxicity was assessed by the MTT assay. Except for P. aeruginosa (MIC ≥2%), all reference strains tested were susceptible to catnip and lemon balm oils with MIC values ranging from 0.016 % to 0.25% (v/v). The clinical isolates were as susceptible to the oils (± 1 serial dilution) as the corresponding reference strains, regardless of their origin and resistance to standard antibiotics. The oils were cytotoxic to both keratinocytes and bronchial epithelial cells at CC50 values from 0.0012% to 0.015% (v/v). Lemon balm oil, whose main components were monoterpene aldehydes, exhibited the highest antibacterial and cytotoxic activity, followed by lemon catnip oil, which contained mainly monoterpene alcohols, and catnip oil, which was characterized by nepetalactones. Our results provide a rationale for the use of catnip, lemon catnip and lemon balm oils in the complementary topical treatment of respiratory tract infections, as the oils show a high antibacterial activity against respiratory tract pathogens, including clinical isolates with reduced susceptibility to standard antibiotics. However, cytotoxicity must be considered in topical therapy.

Ten culinary and ornamental herbs were evaluated for time and quality of rooting of tip cuttings. The taxa included in the study were oregano (Origanum vulgare), lemon thyme (Thymus ×citriodorata), applemint (Mentha suavolens), Persian catnip (Nepeta ×faassenii), lemon balm (Melissa officinalis), southernwood (Artemisia abrotanum), caraway thyme (Thymus herba-barona), hyssop (Hyssopus officinalis), `Blue Wonder' catnip (Nepeta `Blue Wonder'), pineapplemint (Mentha suavolens var. variegata). Four replicates of each species were used. The cuttings, untreated and rooting hormone treated, were placed under intermittent mist, then cuttings potted when a 1- to 1.5-inch root ball had developed. Most of the stock suffered from some chlorosis during rooting; southernwood cuttings particularly displayed severe chlorosis which was overcome with 2 weeks of constant-feed fertilizer after potting. Oregano displayed the best results, rooting in seven days with or without treatment. It produced a sellable 4-inch pot in 31 days from sticking the cuttings. Lemon thyme, applemint, Persian catnip, and lemon balm all rooted in 14 days if treated. No difference was observed in days to rooting between treated and untreated lemon thyme. Untreated cuttings of lemon balm, applemint, and Persian catnip rooted in 25 to 30 days. Treated applemint cuttings not only rooted more quickly but produced a marketable 4-inch pot in significantly less time. Southernwood and caraway thyme rooted in 25 days, with no significant difference between treated and untreated cuttings. Hyssop, pineapplemint, and `Blue Wonder' catnip took about 30 days, also with no significant difference between treated and untreated cuttings.
