The aim of the current research was to find the best plant growth regulators for the multiplication of Sarracenia purpurea. Murashige and Skoog medium (MS) was prepared with macronutrients and micronutrients at 1/3 strength, full strength vitamins, supplemented with 30 g/l sucrose and 5 g/l phytagel and autoclaved. After cooling 0.5 mg\l α-naphthaleneacetic acid (NAA), 5 mg\l 6-benzyladenine (BA) or 0.5 mg\l NAA + 3 mg\l BA were added. Young S. purpurea plants were selected and transferred to media with or without plant growth regulators and cultured for 12 weeks. At the end of this time frame number of roots, root length (cm) and number of shoots were evaluated and differences were analysed by the analysis of variance and interpreted using the Tuckey test. The largest number of roots grew in medium supplemented with 0.5 mg\l NAA but the the absence of plant growth regulators increased their length. The best conditions for shoot multiplication were provided by supplementing 1/3MS with 5 mg\l BA.

This research was conducted to study the effect of some plant growth regulators on in vitro shoots multiplication of stevia (Stevia rebaudiana Bertoni). The experiments included tests of various combinations of KIN with IBA or IAA in the shoot multiplication. Results indicated that KIN at 1.0 mg. L-1 plus 0.3 mg. L-1 of IBA produced the highest number of shoots (3.5 shoots) while KIN at 1.5 mg. L-1 plus IBA at 1.0 mg. L-1 produced the lowest shoot length (1.14 cm).  Hormone free medium produced the highest rate of the leaves number reached 28.56 leaves. KIN and IBA interaction increased fresh and dry weight significantly.   Treatment contained 2.0 mg -1 KIN plus 0.3 mg. L-1 IBA produced the highest fresh weight (1.739 g) while 0.5 mg. L-1 KIN and 0.3 mg. L-1 IBA produced the highest dry weight (0.822 g). As for the effect of interaction between the IAA and KIN it was significant in the number of shoots formed. Interaction between 1.0 mg. L-1 KIN with 0.1 mg. L-1IAA produced the highest number of shoots (3.8 shoots). Shoots length reached 8.10 cm in the media with 0.3 mg. L-1 IAA only. The highest fresh weight (1.267 g) was achieved with the interaction between 1.0 mg. L-1 KIN and 0.3 mg. L-1 IAA while 0.5 mg. L-1IAA without KIN produced the highest dry weight reached 0.138 g.  Shoots multiplication was improved by incorporation of the cytokinin TDZ in culture media. Shoots number, fresh and dry weights were increased significantly by adding 0.05 mg. L-1 of TDZ at present of 0.3 mg. L-1 of IBA giving 6.6 shoots, 0.974 g and 0.144 g respectively while shoots length decreased significantly as media without TDZ produced the highest shoots length reached 9.32 cm. The above results can adopt for the successful in vitro shoot multiplication of Stevia plants.

Gerbera plant Gerbera jamesonii is classified according to the flower colors to four strains: white, yellow, pink and purple. Capitulum and scape explants were tested on MS medium in half or full salts strength, supplemented with different combinations of plant growth regulators cytokinins kintin (Kin) and benzel adinine (BA), auxin indolacitic acid (IAA). Results revealed that the capitulum showed better response to shoot formation 64.13% whereas the scape did not show response. Yellow flowers showed higher response in shoot formation 37.5% than other strains. growth regulators combination BA and IAA (3.0 + 0.1) mg/L respectively showed better response for shoot multiplication. Auxin IBA (0.5) mg/ L gave better rooting percentage 60% than other auxins IAA and NAA all concentrations. The acclimatization of the gerbera was 78.59%.

Propagation Methods

Vitis amurensis ‘Cheongsan’ is a plant with high economic value in both medical and agricultural applications. However, its utilization has been restricted owing to difficulties encountered when applying traditional mass propagation methods, requiring instead application of in vitro propagation methods for their mass scale production. Hence, this study was conducted to find the optimal plant growth regulators for shoot multiplication and root induction during in vitro propagation. Among the three cytokinins used at multiple concentrations for culture initiation and shoot multiplication, the most positive response was found with MS medium containing 5.0 μM 6-benzyladenine (BA), compared to more modest responses from other types of cytokinin, such as kinetin (KIN) and thidiazuron (TDZ). For root induction, medium supplemented with α-naphthaleneacetic acid (NAA) produced a callus and inhibited shoot growth in explants, whereas indole-3-butyric acid (IBA) and indole-3-acetic acid (IAA) did not create any significant problems, but did display differences in root induction efficiencies. Generally, root induction responses with IBA were better that those with IAA. The maximum rooting rates were observed without callus formation and no shoot growth inhibition from explants grown on media supplemented with 0.67 μM IBA. Further, inter-simple sequence repeat (ISSR) analyses revealed that micropropagated plantlets generated in medium supplemented with 5.0 μM BA and 0.67 μM IBA did not lead to genetic variation. Therefore, the application of the in vitro propagation method developed in this study could be used on a commercial scale and will offer opportunities to strengthen the industrial use of V. amurensis ‘Cheongsan’.

The present study was conducted to improve upon the micropropagation protocol of Rose cultivars by modification of the MS medium through variations in sucrose and agar concentrations thereby enhancing the shoot multiplication and rooting efficiency of the nodal explants. High sucrose concentrations and low agar concentrations favoured shoot mutiplication during the in vitro stages. Enhanced multiplcation and growth was observed on sub culturing the mother explants with regenerated shoots on fresh MS medium containing sucrose (3.5%, w/v) and agar (0.6%, w/v), supplemented with lower concentrations cytokinin combination of BAP and KN (2.5 mgl-1+1.5 mgl-1) respectively. Half strength MS medium containing sucrose (2.0%, w/v) and agar (0.3%, w/v) with NAA and BAP (2.0 mgl-1+0.5 mgl-1) in combination was most effective for rooting.

AbstractThe purpose of the presented study was to determine the best mineral composition of media and plant growth regulators in the micropropagation of the ‘Gisela 5’ (Prunus cerasus×P.canescens) dwarf sweet cherry rootstock. Nodal explants from young healthy shoots were excised and cultured on Murashige and Skoog medium without growth regulators.In vitroraised shoot tips were transferred to three culture media including Murashige and Skoog (MS), Driver and Kuniyuki (DKW) and Lloyd and McCown (WPM) containing benzyl adenine (BA) (0.5, 1 or 2 mg·l−1) in combination with kinetin (Kin) at 0 or 0.5 mg·l−1. WPM and DKW media were proving to be the most effective, resulting in a higher percentage of shoot multiplication and shoot number as compared to MS. BA in concentration 2 mg·l−1resulted in the highest number of microshoots per explant (3.1). For rooting, 0, 0.5, 1 or 2 mg·l−1indole-3-butyric acid (IBA) on MS, DKW and WPM media were tested. WPM medium containing 2 mg·l−1IBA was most effective for rooting (93.7%) in comparison to MS (53.1%) and DKW (14.0%). Rooted plantlets were successfully hardened and established in pots.
