The present study aims to evaluate different techniques for breaking the dormancy of <em>R. tomentosa</em> seeds. A randomized design was used to evaluate different techniques for breaking the dormancy of <em>R. tomentosa</em> seeds, including de-operculum, chemical scarifications, and exogenous gibberellic acid (GA<sub>3</sub>), in both laboratory conditions at ambient temperature (25 ± 2 °C) and field conditions. The characteristics of <em>R. tomentosa</em> fruit and seeds were assessed. The average mass, width, and length of fruits were 1.90 g, 13.78 g, and 15.27 g, respectively. The average seed/ripe fruit contained 57 seeds, and the mass of 1000 seeds was 2.64 g. Seed viability (100 %) was achieved in the treatment with 0.075 % tetrazolium at 45 °C for 3 h, but a germinated seed was only 13.00 %. The study of breaking seed dormancy in laboratory conditions revealed that de-operculum significantly enhanced seed germination up to 83.00 % within 15 days, compared with control treatment of 13.00 % within 34 days (p ≤ 0.01). In contrast, 10 % KNO<sub>3</sub> for 24 h under field conditions resulted in the highest seed germination rate of 91.00 % within 34 days, while de-operculum treatment showed 63.00 % of seed germination within 15 days. In addition, the seed water imbibition rate between control and de-operculum seeds was evaluated. The results demonstrated that the control seeds absorbed water more slowly than the de-operculum seeds, indicating that de-operculum promoted faster germination. The findings concluded that breaking seed dormancy is important for <em>R. tomentosa</em> seed germination. De-operculum and KNO<sub>3</sub> were discovered to be effective ways of breaking seed dormancy in <em>R. tomentosa</em>.</p></div>","PeriodicalId":15136,"journal":{"name":"Journal of Applied Research on Medicinal and Aromatic Plants","volume":"42 ","pages":"Article 100558"},"PeriodicalIF":3.9,"publicationDate":"2024-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141292236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was conducted in the North-western Himalaya of India to understand the reproductive biology, breeding system and pollination ecology of <em>D. hatagirea</em>; an endemic and critically endangered orchid. It is a perennial herb that grows along the altitudinal gradients of 2100–3107 m.a.s.l. and overcomes harsh winters through underground perrenating tubers. The flowering commences from May to July and the flowers are completely zygomorphic with male and female reproductive organs fused to constitute gynostemium. Analysis of variance (ANOVA) show significant statistical difference (p < 0.05) between the floral traits for most of the characters. Each flower bears two dark green colored pollinaria with an average of 212.14 ± 14.4 pollinia. Pollen occur as tetrads and polyads in massulae and their viability was greater than 95 ± 4.2 %. Stigma receptivity was confirmed on the day of anthesis and reaches its peak on 5–6th day. Cruden outcrossing index (5), asynchronous anthesis, conspicuous inflorescences, nectaries, presence of rostellum and herkogamy points towards outcrossing nature while pollen ovule ratio (1.27 ± 0.4) and the greater value of self-incompatibility (0.9) reflect that plants are potent cross-breeders. Pollination treatments significantly impacted seed set in <em>D. hatagirea</em> (one-way ANOVA; <em>F</em> = 23.14; p = 0.001) with an average seed set of 92.75 % ± 0.95 for manual xenogamy (p < 0.01), 89.5 % ± 2.38 for geitonogamy (p < 0.01) and 17 % ± 2.2 for bagged inflorescences (p<0.05).

This work is aimed to study the chemical composition of essential oils (EOs) of lavandin from clones ´Grosso´ and ´Super´ cultivated in Spain. For this purpose, 215 EOs, obtained by steam distillation between 2016 and 2022 in agricultural farms located in 13 provinces of Spain, were analyzed by gas chromatography (GC) in three public R&D centers: the Regional Institute for Agrifood and Forestry Research and Development of Castilla-La Mancha (IRIAF), the Agrarian Technological Institute of Castilla y León (ITACyL) and the Agrifood Research and Technology Center of Aragon (CITA). The chemical composition of the EO of lavandin showed great inter- and intra-varietal variability, with the main compounds being linalool, linalyl acetate, camphor and 1,8-cineole. The results showed that the contents of camphor and 1,8-cineole were higher in ´Grosso´ (7.2% <em>vs</em> 5.0% and 5.7% <em>vs</em> 3.8%, respectively), while those of linalool and linalyl acetate were higher in ´Super´ (35.8% <em>vs</em> 34.2% and 33.7% <em>vs</em> 27.2%). Among minor compounds, the lavandin 'Super' exhibited a higher content of β-Z-ocimene and β-E-ocimene, and a lower content of terpinen-4-ol compared to 'Grosso´. Additionally, eleven compounds of lavandin 'Grosso' were compared within the ranges established by ISO 8902:2009 standard, revealing that only 18% of the samples complied with it for all of these compounds. In this sense, the contents of α-terpineol, linalool and lavandulyl acetate were above the upper limit of the standard in respectively 49%, 23% and 21% of the samples. On the contrary, 36% of the samples for β-Z-ocimene and 32% for linalyl acetate were below the range of this regulation. Unfortunately, these discrepancies with the ISO regulation exclude numerous EOs from the market despite their value in different sectors like perfumery, cosmetics, aromatherapy, phytosanitary or pharmacy.

It is a fast-growing herbaceous annual with high nutritional relevance. The present work was designed to determine the effect of six soluble salts (NaCl, Na<sub>2</sub>SO<sub>4</sub>, KCl, CaCl<sub>2</sub>, CaCO<sub>3</sub>, and MgCl<sub>2</sub>) on germination of <em>P. oleracea</em> seeds. The effect of salinity was tested on final germination percentage (FGP%), and germination tolerance index (GTI%) using five concentrations (0, 200, 300, 400, and 600 mM) of each salt. In addition, laboratory experiments were conducted to assess the effects of salinity on germination recovery from high saline conditions (600 mM). Salinity level and salt composition significantly influenced germination attributes. <em>P. oleracea</em> seeds were non-dormant, exhibited approximately 100% germination in distilled water. Both FGP and GTI gradually decreased with increasing salinity. This study showed that seeds of P. oleracea can germinate under 300 mM in all tested salts. The salts causing germination inhibition exhibited specificity, with an increasing trend observed in the following sequence: MgCl<sub>2</sub> > Na<sub>2</sub>SO<sub>4</sub> > NaCl > KCl > CaCl<sub>2</sub> > CaCO<sub>3</sub>.
