Marumi kumquat (Fortunella Japonica) is culture for its valuable nutritional value and medicinal importance in many regions of the world. The current study aimed to evaluate the effect of two types of media enriched with different concentrations of fructose and different plant growth regulators and different fructose concentration on in vitro propagation of Fortunella Japonica. The findings showed that the most effective treatment for explant surface sterilization was by using 0.1% HgCl2 for ten minutes which give best results for production contamination-free explants at the initiation cultures. At multiplication stage, WPM medium gave better results at all tested BA levels as compared with MS medium. No significant differences were showed by using BA alone or in combination with GA3 in the measured parameters. It has been observed that WPM medium supplemented with 0.5mgl-1 BA with the presence of 30mgl-1 fructose was able to give the highest shoot length (1.56cm) with maximum shoots number/explant 9.0 and highest leaves number/explant (21.0). The proliferated shoots were exposed to full strength MS medium salts supplemented with 2mgl-1 NAA which showed the highest ratio of rooting. In vitro rooted plantlets were gradually acclimatized and transferred to open air conditions, which recorded a high survive rate reached to 92%

Conditions for in vitro multiplication and flowering of Drosera spatulata plants were established. Shoot tips of greenhouse-grown plants were sterilized with 1% or 0.5% sodium hypochlorite. The influence of different media concentrations, hormone supplementation, and pH was investigated. Full MS medium without growth regulators was the best for regeneration and multiplication of plants. Regenerated shoots rooted spontaneously on medium without growth regulators and without transfer to additional medium. In 3 months, 100 to 200 plants were generated per explant. Flowering was induced on media supplemented with plant growth regulators. Plants were acclimatized on sterile peat.

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.

Jatropha (Jatropha curcas L.) is an oil bearing crop growing in tropical and subtropical parts of the world. The present study was undertaken to investigate the effects of different plant growth regulators on in vitro callus induction in physic nut (J. curcus). In the present study, it was observed that all the explants viz., leaf lamina, petioles, nodal segments and cotyledonary nodes showed good callus induction responses on various culture media thus tried. Leaf lamina and petioles showed 100.0% callus induction responses on different MS media supplemented with auxins and cytokinins alone or in combinations whereas, nodal segments and cotyledonary nodes showed maximum 89.6% and 83.9% callus induction respectively. The presence of 2, 4-D in culture media with auxins or cytokinins was essential for good callus growth. Among different explants tried, leaf lamina was the best responding explants and MS-13 media supplemented with 5×10-6 M NAA and 10-5 M 2, 4-D is the best callusing and growth supporting medium. However, the regenerative competence of the callus tissues can differ depending on the type of explants used because certain types of plant tissues have more favorable regeneration responses than others. Callus induction rate from all explant types was highest than other reports. The results obtained in the present study would facilitate the high callus induction and regeneration responses in J. curcus for its improvement using biotechnological tools.

<p><em>Beclardia macrostahya</em> is one of the rarest orchids in Mauritius. <em>In vitro</em> techniques are being used for mass propagating this orchid for subsequent restoration programs. Successful asymbiotic germination <em>of</em> <em>Beclardia macrostachya </em>was obtained through embryo rescue. Modified half MS media supplemented with 10% coconut milk was used as basal culture media and the effect of plant growth regulators at different concentrations on embryo development was assessed through qualitative and quantitative parameters. Diameter of embryos, length of protocorm-like bodies (PLBs) and length of developing shoots were calculated using digital photography. Maximal growth was obtained in treatments without any plant growth regulators and 0.5mg/l N<sup>6</sup> Benzyl Amino Purine (BAP). Higher levels of Thiadurazon/TDZ (0.3mg/l) and BAP (1.0 mg/l) though they stimulated embryo development faster, yielded higher level of necrosis later. The results also suggest that plant growth regulator treatments that stimulate fastest embryo development from immature embryos/ovules need not be reliable for further development to PLB and plantlet regeneration.</p>

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.

Oil palm (Elaeis guineensis Jacq.) has become the largest traded vegetable oil in the world due to its innumerable uses and its huge economic importance. Which increases the requirement of quality seedling but the conventional seed production limits the commercial seed production with its long germination period and low germination rate. In this context in vitro germination of zygotic embryo could be a promising alternative. Hence in this study the effect of culturing media, plant growth regulators and genotypes were assessed on in vitro regeneration and plantlet development of oil palm zygotic embryos. Zygotic embryos of four elite genotypes were cultured on MS, N6 and Y3 media, with or without plant growth regulators (NAA, BA and GA3-0.2mg/lt). There was no effect of culture media, plant growth regulators and genotypes on germination of zygotic embryos. Whereas on the growth and development of in vitro plantlets, there was a significant effect of culture media and genotypes. Where culture media N6 performs well and Y3 has shown more abnormality. In case of genotypes, genotypes G1 and G2 shown better performance when compared to genotypes G3 and G4. The effect of plant growth regulators on germination and plant growth was non significant.
