  1. Experiment No 1 In vitro seed germination

  2. Overview 1 2 Experiment Material and Chemicals Introduction Procedure Objective 3 4 5

  3. Introduction

  4. In vitro • More detailed or more convenient analysis of the components of an organism that have been removed from the intact organism is called as in vitro. • Common examples of in vitro experiments include work that uses cells derived from multicellular organisms (cell culture or tissue culture) • Advantages and disadvantages of In vitro studies.

  5. Examples of In vitro Experiments • Polymerase chain reaction • Protein purification • In vitro fertilization • In vitro diagnostics Capsule Dissolution Time: In Vitro Dissolution in 37C (98°F) Water

  6. Germination • Germination is the process by which plants, fungi and bacteria emerge from seeds and spores, and begin growth. • Germination can imply anything expanding into greater being from a small existence.

  7. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. Mixed bean sprouts

  8. Seed Germination • Seed germination is the growth of an embryonic plant contained within a seed; it results in the formation of the seedling. • Empty and Dormant seeds • Role of certain hormones in seed dormancy • Self-incompatibility

  9. Factors affecting germination • Water • Oxygen • Temperature • Light or darkness • Germination rate and Germination capacity

  10. In vitro seed germination In vitro seed germination is the process of germination of embryo of seed in lab by providing favorable conditions for growth as living system.

  11. Experiment for In vitro Seed Germination

  12. Apparatus and Chemicals • Petri dishes • Flask • Autoclave • Laminar flow • Aluminum foil • Forceps • Digital Balance • HgCl2 • Agar

  13. Layout and protocol of the Experiment

  14. Seed Preparation Soaking of seeds Distilled water is used Autoclave to avoid contamination Preparation of Agar Agar +Tap water Do not dip into HgCl2 overnight Laminar flow hood is used Surface Sterilization of seeds HgCl2 is used

  15. Propagation of seed germination Washing of seeds Use of Laminar flow hood+ hands should be washed properly Seed coat is removed Provide favorable conditions for growth Transfer of seeds in test Petri dishes Agar+ prepared seeds Placement in growth room

  16. Protocol • Soak seeds in distilled water for 2-3 hours. • In order to prepare plain agar dissolve 1 gram of agar is in 100 ml of tap water and autoclave it with other necessary apparatus in autoclave at 120c for 20 min. • Take all apparatus in laminar flow to avoid contamination. • For surface sterilization of seeds dip them into HgCl2 solution for few seconds.

  17. Wash them 2-3 times and then remove seed coats. • Place those seeds in test tube with the help of forceps, in which solidified agar media is present. • Plug them and cover lower tide with aluminum foil and place them in growth room for a day and check the growth of roots and shoots.
