    Phyton-International Journal of Experimental Botany, Vol.93, No.3, pp. 427-444, 2024, DOI:10.32604/phyton.2024.046271

    Abstract An effective in vitro propagation protocol was designed for Lavandula angustifolia Miller, a medicinal aromatic plant that is a prominent source of volatile organic compounds (VOCs). Murashige and Skoog media were supplemented with various concentrations of Plant Growth Regulators (PGRs), and the growth parameters of the nodal segments were examined. Nodal explants formed callus when they were supplemented with 2 mg/L of 6-Benzylaminopurine (BAP). The superior hormonal concentration of Murashige and Skoog (MS) media for the proliferation of shoots from callus cultures (39.33%) was 5 mg/L of 2-Isopentenyl adenine (2iP), and the favorable media for the growth… More >

    Phyton-International Journal of Experimental Botany, Vol.93, No.2, pp. 277-289, 2024, DOI:10.32604/phyton.2024.046989

    Abstract Tilia amurensis is an economically valuable broadleaf tree species in Northeast China. The production of high-quality T. amurensis varieties at commercial scales has been greatly limited by the low germination rates. There is thus a pressing need to develop an organogenesis protocol for in vitro propagation of T. amurensis to alleviate a shortage of high-quality T. amurensis seedlings. Here, we established a rapid in vitro propagation system for T. amurensis from mature zygotic embryos and analyzed the effects of plant growth regulators and culture media in different stages. We found that Woody plant medium (WPM) was the optimal primary culture medium for… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.10, pp. 2331-2348, 2022, DOI:10.32604/phyton.2022.021273

    Abstract Aconitum vilmorinianum, a well-known traditional Chinese herb, is recently being threatened by overexploitation and environment disturbance. This study was conducted to provide propagation methods through in vitro germination and explant cultivation. Germination was stimulated up to 66.00% on Murashige and Skoog (MS) medium containing 2.0 mg L−1 6-benzylaminopurine (BAP), 0.1 mg L−1 1-napthaleneacetic acid (NAA), and 30 g L−1 sucrose. Three bacteria (Pantoea agglomerans, Erwinia persicina, and Pseudomonas tolaasii) would be responsible for consistent contamination during germination. The latter two were effectively eradicated after disinfected. The influence of explant types and hormone combinations on direct and indirect organogenesis was evaluated in the… More >

    Phyton-International Journal of Experimental Botany, Vol.90, No.3, pp. 1003-1013, 2021, DOI:10.32604/phyton.2021.012862

    Abstract Agave guiengolaGentry is an endemic plant from a very small locality in Oaxaca, Mexico. Its conservation status is fragile and can rapidly worsen. Because of its scarcity, this agave has been used solely for ornamental purposes, but it could have other uses if more plants were available. In vitro propagation by enhanced axillary sprouting from stem segments was attained using Murashige and Skoog Basal Medium (MS) as well as basal medium supplemented with cytokinins 6-Benzylaminopurine (BA) or 6-(γ,γ-Dimethylallylamino)purine (2iP). The best treatment for shoot induction in semisolid medium consisted in MS supplemented with 2 mg l–1 BA, obtaining… More >

    Organogenesis and plant regeneration of Arachis villosa Benth. (Leguminosae) through leaf culture


    BIOCELL, Vol.33, No.3, pp. 179-186, 2009, DOI:10.32604/biocell.2009.33.179

    Abstract With the aim of developing an efficient plant regeneration protocol, leaflet explants of three accessions of Arachis villosa Benth. (S2866, S2867 and L97) were cultured on basic Murashige and Skoog medium supplemented with different combinations of plant growth regulators: α-naphthalenacetic acid, indole-3-butyric acid, 6-benzylaminopurine, kinetin and thidiazuron. The accession L97 was the only one able to differentiate buds through indirect organogenesis. The most suitable combination for bud regeneration was the basic medium added with 13.62 μM thidiazuron and 4.44 μM 6-benzylaminopurine. These results show the important role of the genotype in morphogenetic responses and the organogenetic effect of More >

    Inhibitory effect of jasmonic acid and ethylene on epicotyl growth and bud induction in the maritime pine, Pinus pinaster Soland. in Ait


    BIOCELL, Vol.33, No.3, pp. 141-148, 2009, DOI:10.32604/biocell.2009.33.141

    Abstract Two independent parameters, epicotyl height (cm) and number of induced buds were studied on Pinus pinaster explants to analyse the effects of three phytohormones (6-benzylaminopurine, jasmonic acid, ethylene) which were combined or not in 11 different treatments. Epicotyle length diminished significantly in relation to the control medium (medium without exogen phytohormones) in presence of jasmonic acid, 6-benzylaminopurine or Ethephon (which is converted to ethylene in plants) in any of treatments. Concentrations of 100 μM of jasmonic acid and Ethephon had a greater inhibitory effect than the treatments with 10 μM. In addition to that, jasmonic acid… More >

    Brief Note : Hydrogen peroxide in micropropagation of Lilium. A comparison with a traditional methodology


    BIOCELL, Vol.30, No.3, pp. 497-500, 2006, DOI:10.32604/biocell.2006.30.497

    Abstract The micropropagation of Lilium longiflorum requires adequate equipment which may not be afforded by small laboratories or producers. In this work we compared traditional methodology with a protocol that included easily available elements to sterilize materials and culture media, together with addition of hydrogen peroxide (H2O2 ) into the nutrient media as chemical sterilizer. A series of H2O2 concentrations (0.005, 0.010, 0.015 and 0.020% p/v) was used to control contamination during in vitro establishment and subsequent cultivation; the explant organogenic response was also examined and compared to the traditional micropropagation technique. The level of culture contamination was within… More >

    BIOCELL, Vol.28, No.1, pp. 13-20, 2004, DOI:10.32604/biocell.2004.28.013

    Abstract An efficient clonal propagation procedure for six rice varieties cultivated in Argentina was developed by using shoot tip cultures, and the genetic stability of the micropropagated plants was verified by isozyme analysis. One week old seedlings obtained on MS medium were sectioned and subcultured on MS medium (0.75% agar) supplemented with different combination and concentrations of cytokinins (BAP and KIN) and auxins (2,4-D and NAA). After four weeks of culture, multiple shoots were obtained. The best response was observed on MS supplemented with BAP 5 mg l-1. Shoot clumps were multiplied in MS liquid medium containing More >
