In vitro culture systems based on liquid culture media are considered to be more effective than semisolid culture medium systems. Liquid culture media systems provide better nutrient availability for plant tissues, easier culture handling, and the potential for scaling up and automation. However, in vitro liquid culture requires more careful handling due to the potential for contamination and the possibility of negative effects, such as hyperhydricity or vitrification, that hinder the growth and development of the plant material. Temporary immersion bioreactors have emerged as a workable alternative for capturing the benefits of liquid media, though semisolid systems are still traditional. Many studies have shown that silicon (Si) is a beneficial plant nutrient. Silicon might have a positive effect in both semisolid and liquid in vitro systems. The objective of this study was to evaluate the effect of silicon on the micropropagation and acclimatization of banana plants cultivated in vitro by comparing liquid temporary immersion bioreactor technology and semisolid traditional culture systems. Different silicon concentrations (0 and 1 mL L-1) and culture systems (liquid temporary immersion bioreactor and semisolid traditional culture) were evaluated over a 36-day period. The growth characteristics plant size, fresh and dry weight, and number and length of leaves and roots were evaluated. After the 36-day in vitro growth period, plants were transferred to a greenhouse for acclimatization and were evaluated after 30 days for the same growth characteristics used in the in vitro studies. The temporary immersion bioreactor system resulted in greater growth of banana plants compared to the traditional semisolid system. Temporary immersion bioreactors also showed a positive interaction with Si and resulted in higher values for all growth characteristics in the acclimatization phase.

Psychotria ipecacuanha, is a plant species with known medicinal properties that is critically endangered due to overexploitation of natural populations. Although the difficulties in conventional propagation by seed and by vegetative propagation are generally understood, the present study enhances our knowledge by describing efficient plant regeneration and root induction protocols for P. ipecacuanha while comparing alkaloid content (emetine and cephaeline) in in vitro-derived tissues. Stem node explants were cultured on MS medium MS supplemented with indolbutiric acid (IBA) in semi-solid media and the RITA® temporary immersion bioreactor. The highest root formation (81%) was in MS + 1.5 mg L−1 IBA in the bioreactor. After 24 months of acclimatization, the plants cultivated in MS + 0.50 and 1.0 mg L-1 of IBA had the highest number of roots (3), with mean values of 10.47 and 9.40 cm, respectively. The cultures coming from 1.0 mg L−1 and 0.5 mg L−1 IBA in the bioreactor contained higher cephaeline content, with a relative area of 14.2 and 14.9%, respectively. For emetine, the 1.0 mg L−1 IBA cultures in the bioreactor, 0.5 mg L−1 IBA and MS0 cultures contained higher content than the other treatments, with a relative area of 10.2, 10.2 and 10.1%, respectively.

This article describes the performance of nodal segments from Habanero pepper (Capsicum. chinense) during shoot induction and elongation under different semisolid and liquid culture conditions with various degrees of ventilation in which they were exposed to different levels of immersion and growth regulators. The ethylene content in non-ventilated containers, the age of the explant donor plants as well as the effect of thidiazuron and paclobutrazol on shoot induction and of gibberellic acid and AgNO3 on shoot elongation were also evaluated. A temporary immersion bioreactor (BioMINT™) was used for the multiplication and elongation of isolated shoots with very good results. We report an efficient protocol for the in vitro propagation of Habanero pepper that produces plants with a high survival rate when transplanted to soil.

Ornamental pineapple is a hard plant with significant landscaping value. Typically, conventional propagation is performed by clump division with low yields, and may even spread diseases. Plant tissue culture is viable, yielding plants with a high phytosanitary and genetic quality over a short time period. This study aimed to verify the in vitro multiplication of ornamental pineapple plants (Ananas comosus var. bracteatus L.) in different micropropagation systems, in association with BAP concentrations. Plants with about 2 cm were used, transplanted to the different treatments: bioreactor, natural ventilation and conventional micropropagation, combined with 3 BAP concentrations (0, 1 and 2 mg L-1). The basic medium used consisted of MS salts. The highest number of shoots and in vitro culture growth were obtained with the use of bioreactor and culture medium containing 2 mg L-1 BAP. The temporary immersion bioreactor allows air renewal inside the bottles, leading to a better performance of in vitro cultivation of ornamental pineapple, when compared to conventional micropropagation.

Summary Embryogenic callus of sago (Metroxylon sagu Rottb.) has been grown on three systems of in vitro culture i.e. agar-solidified medium, liquid medium, and temporary immersion system (TIS) medium to observe and compare the development of embryogenic callus over one passage of six weeks.  A-half gram of embryogenic callus was cultured on a modified MS medium containing 10 mg/L   2,4-D and 0.1 mg/L kinetin. For histological studies, embryogenic callus was fixed in FAA and embedded in paraplast wax. Serial sections were stained with safranin 1% and observed microscopically. By the end of culture period, the development of embryogenic callus in TIS medium was relatively better than those of the other two media.  Fresh weight of callus in liquid medium and TIS increased by 6.5-fold, while on agar-solidified medium increased by 5.4-fold in six weeks.  About 40% of callus in liquid medium and TIS and 20% of callus on agar solidified medium have changed into somatic embryos at globular stage. Histology structure of embryogenic callus of the three systems of in vitro culture shows different pattern. On agar-solidified medium, secondary callus and friable embryogenic callus that consist of meristematic cells were formed. In contrast, more embryogenic cells were formed in liquid medium and TIS to support maturation process to somatic embryos. Therefore, temporary immersion system and liquid medium are recommended for maturation of embryogenic callus, whereas agar-solidified medium is for proliferation of embryogenic callus of sago.  Ringkasan Kalus embriogenik sagu (Metroxylon sagu Rottb.) telah ditumbuhkan pada tiga sistem kultur in vitro yaitu medium padat, medium cair, dan medium dengan sistem perendaman sesaat (SPS) untuk mempelajari dan mem-bandingkan perkembangan dari kalus embrio-genik selama periode enam minggu. Setengah gram kalus embriogenik dikulturkan pada medium MS modifikasi yang mengandung  2,4-D 10 mg/L dan kinetin 0,1 mg/L.  Untuk studi histologi, kalus embriogenik difiksasi dengan FAA dan embedding menggunakan lilin paraplast. Irisan diwarnai dengan safranin 1% dan diamati menggunakan mikroskop. Pada akhir periode kultur, pertumbuhan kalus pada medium dengan SPS lebih baik dibandingkan dengan medium cair dan padat. Bobot basah kalus pada  medium cair dan SPS meningkat 6,5 kali sedangkan pada medium padat meningkat 5,4 kali dalam waktu enam minggu. Sebanyak 40% kalus pada medium cair dan SPS serta 20% kalus pada medium padat berubah menjadi embrio somatik fase globuler. Struktur histologi kalus embriogenik pada ketiga jenis sistem kultur in vitro menunjukkan pola yang berbeda. Pada medium padat terjadi pembentukan kalus sekunder dan kalus embriogenik remah yang terdiri atas sel-sel meristematik. Sebaliknya pada medium cair dan SPS pembentukan sel embriogenik lebih banyak yang menunjang proses pendewasaan menjadi embrio somatik. Oleh karena itu, medium cair dan SPS direkomendasikan untuk pendewasaan kalus embriogenik, sedangkan medium padat untuk proliferasi kalus embriogenik sagu.

The aim of the present research was to verify the in vitro growth of orchids in different systems of micropropagation, being cultivated in a bioreactor, with natural ventilation and conventional systems. Cattleya walkeriana plants were obtained from the germination of seeds in culture medium. After 8 months, seedlings with 1 cm of length were placed in a culture vessel according to the treatments, which counted with two micropropagation systems (conventional and natural ventilation) in three media of culture (liquid, solid with 5 or 6g L-1 of agar). Two additional treatments in bioreactor of temporary and continuous immersion were performed. The design was entirely randomized (ERD), consisting of a 2x3 factorial with two additional treatments, totaling 8 treatments with three repetitions. The temporary immersion bioreactor promoted a bigger growth of the aerial part and of the root system, bigger accumulation of dry mass and better control of water loss by the plants. The temporary immersion bioreactor is the best micropropagation system for the C. walkeriana growth in vitro.
