Comparative Studies on Growth & Biochemical Characteristics of Gerbera Grown on Semi-Solid and Liquid Media




I,in order to excel in Plant Biotechnology, joined this prestigious university as a trainee under the guidance of Mr. Sunil D. Purohit for micro-propagation of plants and their phylogenetic analysis using molecular markers.

In present piece of work, base cultures of Gerbera grown on Agar Gelled semi-solid media were sub-cultured on Agar gelled semi-solid media and Glass bead/liquid media and their growth and biochemical characteristics were studied in two sets after every 15 days.

  • Conclusion Shoots of Gerbera grew much better in liquid phase provided with Glass Beads as compared to those grown on semi-solid media. In addition to better shoots, higher shoot length and more number of leaves with greater surface area were shown in Gerbera grown in liquid media. Higher concentration of Protein and Carbohydrate content in the shoots grown on liquid phase medium with glass beads which showed best growth facilitated by better absorption of nutrients and higher metabolic activity under hydrated condition. Liquid medium is better than semi-solid medium during in-vitro cultivation. The plantlets produced on liquid medium possessed better quality in all respects than the semi-solid ones. Bac

  • Gerbera plant: Gerbera is a genus of ornamental plants fromthe sunflower family (Asteraceae). It was named in honour ofGerman Botanist and naturalist Traugott Gerber (1749) whotravelled extensively in Russia and was a friend of CarlousLinnaeus.Kingdom: Plantae(Unranked): Angiosperms(Unranked): Eudicots(Unranked): AsteridsOrder: AsteralesFamily: AsteraceaeSubfamily: MutisioideaeTribe: MutisieaeGenus: Gerbera
  • 6-Benzylaminopurine, benzyladenine or BAP is afirst-generation synthetic cytokinin thatelicits plant growth and developmentresponses, setting blossoms and stimulating fruitrichness by stimulating cell division. It is aninhibitor of respiratory kinase in plants, andincreases post-harvest life of green vegetables.6-Benzylaminopurine was first synthesized andtested in the laboratories of plantphysiologist Folke K. Skoog.Molecular formula C12H11N5Molar mass 225.25 g mol−1Appearance White to off-white powder Bac
  • FRESH WEIGHT:Plant samples (shoot clusters with leaves) were weighed on the balance after removing any adhering agar. Bac
  • DRY WEIGHT:Plant samples (shoot clusters with leaves) were wrapped in filter paper and kept in oven at 60°C for 12 hours. Dry samples were allowed to equilibrate to room temperature and humidity conditions and weighed to obtain dry weight. Bac
  • PERCENT DRY WEIGHT:Percent dry weight of the plant samples was calculated by the following formula:Percent Dry Weight = Bac
  • Kimberly Wong Stomata Leaf Peel1. Count A fresh leaf and a bottle of nail varnish was taken.2. 2 squares (about 1cm2) on each side (2 on the bottom and 2 on the top) were painted.3. Those patches were allowed to dry.4. A second layer was applied when the first one was completely dry.5. While waiting for the nail varnish to dry, a microscope was taken and adjusted (it was made sure that the light was dim)6. Using forceps, a strip of nail varnish was peeled off from the upper epidermis and observed under 10x.7. The number of stomata were counted when the patch was in focus.8. Steps 6-8 were repeated with a strip of nail varnish from the lower epidermis. Bac
  • The amount of chlorophyll was determined with the help of following formulaChlorophyll ‘a’ mg gˉ¹ fresh leaf =Chlorophyll ‘b’ mg gˉ¹ fresh leaf =Chlorophyll ‘c’ mg gˉ¹ fresh leaf = a = length of light path in the cell (1 cm) V = volume of extract in ml (final volume) w= fresh weight of the sample (leaf) in g.
