Read MoreThis lesson is about seed germination, the process of seeds growing into plants. In this lesson, we''ll go over the steps of germination, and what factors influence how seeds germinate.
Read MoreType # 1. Plant Layout: Plant layout means the disposition of the various facilities (equipments, material, manpower, etc.) and services of the plant within the area of the site selected previously. Plant layout begins with the design of the factory building and goes up to the loion and movement of a work table.
Read MorePlant breeding can be defined as an art, a science, and technology of improving the genetic make up of plants in relation to their economic use for the man kind. or Plant breeding is the art and science of improving the heredity of plants for the benefit of mankind. or Plant breeding deals with the genetic improvement of crop plants also known as
Read MorePlant reproduction is the process by which plants generate new individuals, or offspring. Reproduction is either sexual or asexual. Sexual reproduction is the formation of offspring by the fusion of gametes .Asexual reproduction is the formation of offspring without the fusion of gametes.
Read MoreVegetative reproduction from a stem usually involves the buds. Instead of producing a branch, the bud grows into a complete plant which eventually becomes selfsupporting. Since no gametes are involved, the plants produced asexually have identical genomes and the offspring form what is known as a clone.
Read MorePlant reproductive system, any of the systems, sexual or asexual, by which plants reproduce. In plants, as in animals, the end result of reproduction is the continuation of a given species, and the ability to reproduce is, therefore, rather conservative, or given to only moderate change, during

Read MoreThese steps make up the ''front end'' of the nuclear fuel cycle. After uranium has spent about three years in a reactor to produce electricity, the used fuel may undergo a further series of steps including temporary storage, reprocessing, and recycling before wastes are disposed. Collectively these steps are known as the ''back end'' of the fuel cycle.
Read MoreADVERTISEMENTS: Let us make an indepth study of the introduction, process and types of plant succession. The process of plant succession consists of nine steps. The nine steps are: (1) Nudation (2) Migration (3) Germination (4) Ecesis (5) Colonisation and Aggregation (6) Competition and Coaction (7) Invasion (8) Reaction and (9) Stabilisation.

Read MorePlants have . It''s true. While it may only be a vaguely similar process to the participated in by humans and animals, plants engage in sexual reproduction quite often. There is a series of steps that plants go through to create offspring. It isn''t the most romantic process, but it
Read MoreJul 04, 2019 · Did you know that plants can be cloned? Yes you can make duplie plants for your garden by taking cuttings. The new plant will have identical properties to the original plant and you can repeat this process lots of times. For many plants, the steps are simple and only takes minutes to do.
Read MoreJul 31, 2018 · How to Repot a Plant. Step 1: Choose a larger pot. The main reason for repotting is because the plant has begun to outgrow its current home. You will want to give the roots plenty of room so they can support the beautiful part of the plant you get to enjoy. Make sure the new pot is not only wider, but also deeper.
Read More1 Extraction of Natural Products from Plants – An Introduction Hans J ö rg Bart 1.1 Introduction The history of the extraction of natural products dates back to Mesopotamian and Egyptian times, where production of perfumes or pharmaceutically active oils and waxes was a major business.
Read MoreLeaf Cuttings. Some, but not all, plants can be propagated from just a leaf or a section of a leaf. Leaf cuttings of most plants will not generate a new plant they usually produce only a few roots or just decay. Because leaf cuttings do not include an axillary bud, they can be used only for plants that are capable of forming adventitious buds.

Read More4.2 The science behind Golden Rice. Modifying crops to produce the Bt toxin (Section 3.1) was, in some ways, relatively simple. The toxin is a single protein and can therefore be produced as a result of the insertion of a single gene into the plant''s genome.
Read MoreAdult plants can be produced within a short period of time. Many plantlets can be produced without seeds. Healthy and disease free plants can be propagated by this technique. Endangered plants can be preserved or conserved by this technique. Basic steps of plant tissue culture and its importance

Plant breeding is an art because selection of superior plant requires human skill, imagination and experience. Science development of superior varieties involves genetic principles, sequential steps and experimentation to genetic makeup of crop plant.
Read MoreSelection is the most ancient and basic procedure in plant breeding. It generally involves three distinct steps. First, a large number of selections are made from the genetically variable original population. Second, progeny rows are grown from the individual plant selections for observational purposes.
