Micro Propagation

Banana is important fruit crop in horticulture where it propagates through suckers which takes immense time for production and with low multiplication rate, to overcome these type of situation some protocols have been made such as the micro propagation where the tissue culture of banana is applied with help of plant growth regulators such as auxins and cytokinins are used at different concentration to attain the definite good results till now many studies had been done in the tissue culture of banana. In the present study it was observed that the explants cultured in MS medium containing 4 mg/l BAP + 0.5 mg/l IAA had highest number of shoot buds and number of shoots. Similar result was studied by Muhammad et al. (2007) where the highest multiplication ratio was observed at 4 mg/l BAP along with 1 mg/l IAA. Habiba et al. (2002) and Ahmed et al. (2014) reported that 4 mg/l BAP in combination with 2 mg/l IAA shown remarkable results.

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.

Banana (Musa spp.) is a large herbaceous perennial monocotyledonous and monocarpic plant. It belongs to the family Musaceae. Banana is one of the popular berry fruit which is available to every common person. Banana crop is mostly cultivated through sword suckers, for ease production some in vitro propagation methods came into existence like tissue culture technology. Some of them are micro propagation, clonal propagation etc, For in vitro growth of the excited tissues, plant growth regulators have been considered as one of the most significant factor. Most commonly, auxins and cytokinins are used in the growth and development of the banana explants. The plant growth regulators are required in different concentrations along with Murashige and Skoog media for the best shooting and rooting of the explants.

Ginger (Zingiber officinale Roscoe) var. Bentong is a monocotyledon plant that belongs to the Zingiberaceae family. Bentong ginger is the most popular cultivar of ginger in Malaysia, which is conventionally propagated by its rhizome. As its rhizomes are the economic part of the plant, the allocation of a large amount of rhizomes as planting materials increases agricultural input cost. Simultaneously, the rhizomes’ availability as planting materials is restricted due to the high demand for fresh rhizomes in the market. Moreover, ginger propagation using its rhizome is accompanied by several types of soil-borne diseases. Plant tissue culture techniques have been applied to produce disease-free planting materials of ginger to overcome these problems. Hence, the in vitro-induced microrhizomes are considered as alternative disease-free planting materials for ginger cultivation. On the other hand, Bentong ginger has not been studied for its microrhizome induction. Therefore, this study was conducted to optimize sucrose and plant growth regulators (PGRs) for its microrhizome induction. Microrhizomes were successfully induced in Murashige and Skoog (MS) medium supplemented with a high sucrose concentration (>45 g L−1). In addition, zeatin at 5–10 µM was found more effective for microrhizome induction than 6-benzylaminopurine (BAP) at a similar concentration. The addition of 7.5 µM 1-naphthaleneacetic acid (NAA) further enhanced microrhizome formation and reduced sucrose’s required dose that needs to be supplied for efficient microrhizome formation. MS medium supplemented with 60 g L−1 sucrose, 10 µM zeatin and 7.5 µM NAA was the optimum combination for the microrhizome induction of Bentong ginger. The in vitro-induced microrhizomes sprouted indoors in moist sand and all the sprouted microrhizomes were successfully established in field conditions. In conclusion, in vitro microrhizomes can be used as disease-free planting materials for the commercial cultivation of Bentong ginger.

Amygdalus Communis

The Almond (Amygdalus communis) is one of the most important and oldest commercial nut crops, belonging to the Rosaceae family. Almond has been used as base material in pharmaceutical, cosmetic, hygienically and food industry. Propagation by tissue culture technique is the most important one in woody plants. In the current research, in vitro optimization of tissue culture and mass production of almond was investigated. In this idea, explants of actively growing shoots were collected and sterilized, then transferred to MS medium with different concentrations and combinations of plant growth regulators. The experiment was done in completely randomized blocks design, with 7 treatment and 30 replications. After 4 weeks, calli induction, proliferation, shoot length and number of shoot per explants were measured. Results showed that the best medium for shoot initiation and proliferation was MS + 0.5 mg/l IAA (Indol-3-Acetic Acid) + 1 mg/l BA (Benzyl Adenine). Autumn was the best season for collecting explants. The shoots were transferred to root induction medium with different concentrations of plant growth regulators. The best root induction medium was MS + 0.5 mg/l IBA (Indol Butyric Acid).

Surface Sterilization

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%

Both greenhouse-grown white ash plants derived from tissue culture and rooted microshoots in high humidity trays were inoculated with 11 tumor-inducing Agrobacterium strains. Eight strains stimulated mutative gall formation. Plants inoculated with strain A281 exhibited a higher frequency of callus formation (greenhouse-22.2%; microshoots-18.8%) than other strains at the site of the wound. Therefore, strain A281 was used to inoculate seed and seedling explants in vitro. Explants were placed on MS medium containiner no plant growth regulators and inoculated at 0, 3, 5, 7, or 10 days after initiation. Plants inoculated at 10 days showed a higher frequency of callus formation (16.4%) than with earlier inoculations. Also, rewounding of the explant at inoculation resulted in a higher frequency of callus formation (11.3%) compared to not rewounding the explant (3.9%).

ABSTRACT: The aim of the study was to develop optimum composition of plant growth regulators in media for the propagation and rooting of shoots of stevia (Stevia rebaudiana Bertoni) in in vitro cultures. Single-node shoot fragments obtained from plants propagated on MS medium were placed onto media supplemented with: BAP, 2iP and KIN at concentrations: 0.5, 1, 2 and 5 mg∙dm-3, whereas at the rooting stage with addition of: IAA, IBA and NAA at concentrations 1, 2, 4 and 8 mg∙dm-3. The highest number of shoots and leaves was reported for plants propagated on MS medium enriched with 0.5 mg∙dm-3 BAP. The greatest number of the longest roots was developed by stevia on the MS medium enriched with 1 mg∙dm-3 IAA.
