Effects of foliar spraying of l-phenylalanine and application of bio-fertilizers on growth, yield, and essential oil of hyssop [Hyssopus officinalis l. subsp. Angustifolius (Bieb.)]

Recent Development in Micropropagation Techniques for Rare Plant Species

“…Of the 12 tested variants of nutrient media, the highest percentage of rooting in vitro were found on the half MS and MS media—the percentage of rooting in both variants reached 40% ( Table 5 ). At the same time, our data contradict the results of other studies, where WPM (woody plant medium) and QL (Quorin and LePoivre) with the addition of NAA (1-naphthaleneacetic acid) at a concentration of 0.1 mg/L are indicated as the most effective variants of nutrient media for rooting in vitro H. angustifolius [ 59 , 60 ]. This may be due to the fact that some of researchers distinguish H. angustifolius as a variation of H. officinalis , rather than as a separate species, and most of the nutrient media are presented for H. officinalis [ 58 ].…”

“…The reasons for the rarity of H. angustifolius on the territory of the Rostov region include narrow ecological amplitude, low competitiveness, anthropogenic violations of habitats and collection as a valuable medicinal plant [ 3 , 50 , 51 ]. Many researchers distinguish H. angustifolius as a variation of H. officinalis , rather than as a separate species [ 58 , 59 ]. The H. officinalis and its related species are valuable medicinal plants [ 60 ].…”

Evaluation of the Conditions for the Cultivation of Callus Cultures of Hyssopus officinalis Regarding the Yield of Polyphenolic Compounds

“…Hyssopus officinalis callus cultures were used to obtain styrenes and triterpenes [15]. In accordance with previous results, laboratory samples of H. officinalis callus were obtained [16], the chemical composition of H. officinalis callus used for the biotechnological production of phenolic compounds was studied, and the optimal composition of nutrient media was determined. In [17], the sequence of histogenesis and organogenesis in the in vitro callus of nodal explants of H. officinalis was studied upon treatment with growth regulators.…”

Pruning intensity and amino acids tryptophan and glycine on growth and flowering of Jasminum sambac

“…The content of essential oil with all level of pruning except 40 cm was the highest with glycine, and in the level of 75 cm there is no significant difference between two amino acids (Table 2). Aghaei et al (2019) indicated that spraying of l-phenylalanine on hyssop increased growth and growth characteristics and essential oil of aerial parts of plants. They explained that the supplying of nitrogen through amino acids caused the increased activities of photosynthesis pigments and secondary metabolites such as essential oil.…”
