Auxin

coleoptile produces a chemical called auxin • auxin is a hormone that stimulates the cells below the tip (called the zone of elongation) too expand, up to three times their original length • exposure to light inhibits the production of auxin (it alters an oxidation process to change it into something useless) • So on the side of the plant light shines on, much less auxin is produced. On the side with less light, more is able to be produced • all the auxin produced travels down the plant into

Abscission is the process by which a plant drops one or more of its parts including leaves, fruits, flowers or even seeds. Plants may undergo this process of abscission in the purpose of either to discard its part that is no longer necessary, such as a leaf during autumn, or a flower following fertilisation or even for the purposes of reproduction. Most deciduous plants drop their leaves by abscission before winter, whereas evergreen plants abscise their leaves continuously. Another form of abscission

The Effect of Gibberellic Acid on Wild Type and Rosette Brassica rapa Plants Intro This experiment was performed to test two hypotheses concerning the plant hormone gibberellic acid and a mutant rosette shaped phenotype of the plant Brassica rapa. This experiment was done in order to test the effects o gibberellic acid on plants and its effect on rosette shaped complexes. The two hypotheses in this experiment are as follows: Hypothesis number one states that Gibberellic acid allows for stem elongation

signals released by a tissue and delivered to a receptor tissue. Auxin is the hormone most commonly found in plants. Auxin regulates and aids in the development of plants (Kazan 2013). The acid growth hypothesis states that an acidic ph will enhance the effects of auxin in seed development and plant growth. Radish seeds were planted in acidic soil and administered natural and synthetic auxin in order to test for the effect of synthetic auxin in an acidic soil on plant growth. The reason for this experiment

The increasing in the world’s population nowadays has lead to the increase in the demand for food. It is being a priority for the crops and food industries to find a solution to this matter in order to produce high amount of food and provide good quality food for the consumers. This is where the technology of plant tissue culture steps in. As Lineberger (n.d) mentions, plant tissue culture can contributes to the agriculture industry in the future and give advantageous to the growers because the mass

control. The synthetic auxin found in SUPERthrive, indole-3-bytric acid, may be a key player in the benefits of SUPERthrive, if there are any. For example, indole-3-acetic acid (IAA), the main auxin in higher plants, has been found to have positive effects on plant growth and development. Auxin is able to stimulate differential growth, specifically in response to gravity or light stimuli. Another important aspect of auxin is its ability to detect developmental defects caused by auxin deficiency. With SUPERthrive

The article explores the possibility of plants that we consume such as vegetables, fruits or other edible plants, containing remaining hormones that may have both positive and negative impacts on our health. Recent studies have indicated that there may be a connection between our gut microbes stimulating the creation of molecules in response to the remnants of hormones in plant matter. Positive impacts look at ABA-rich foods as a way to protect against and fight off cancers cells, and also to regulate

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

ETYMOLOGY OF ANDROGRAPHIS PANICULATA A. paniculata is a large genus of herbs found in the Indo-Malaya, Africa, Brazil and also the central of America Northward into Mexico (Alagesaboopathi, 2000). It is an annual plant which grows to the height of 1 – 3 ft. It is one of the most widespread plants used in the Unani and Ayurvedic traditional medicines. It is an erect and branched plant with lanceolate green leaves (Rammohan, 2009) 2.2. DISTRIBUTION OF ANDROGRAPHIS PLANT A. paniculata consists of 28

Discussion Shoot regeneration using TDZ and BAP Recently, many research groups have been involved in establishing reliable regeneration procedures for agronomically and industrially important plants, because it would be a primary step to facilitate introduction of genes and improvement of the crops. In vitro regeneration system is the first step towards transformation and once successfully attempted, can pave the way for the development of genetically transformed plants with desired traits (Pérez-Molphe-Balch
