• Plant Growth Promoters are those substances used for better management of Nutrients and Plant growth. These Plant Growth Promoters play a major role in seed germination, fruit ripening, enhances uptake of nutrients, boost protein synthesis, augment immunity and helps to withstand stress conditions, reduce flower and fruit drop and help in better plant growth.
• Commonly plant growth regulators are auxins, cytocinin, gibberellins, ethylene etc.
Effect of Amino Acids On Plants
The requirement of amino acids in essential quantities is well known as a means to increase yield and overall quality of crops.
Amino Acids are also supplied to plant by incorporating them into the soil. It helps in improving the micro flora of the soil thereby facilitating the assimilation of nutrients.
Amino Acids help to increase chlorophyll concentration in the plant leading to higher degree of photosynthesis. This makes crops lush Green
Increase crop yield and quality. Even though plants have the inherent capacity to biosynthesize all the amino acids needed from nitrogen, carbon oxygen and hydrogen, the biochemical process is quite complex and energy consuming. As such, the application of amino acids such as those contained in HYT Nutrition allow for the plant to save energy on this process, which can be dedicated to better plant development during critical growth stages.
Amino acids are fundamental ingredients in a protein’s biosynthetic process and nearly twenty amino acids types are involved in biosynthetic processes. Studies have shown that amino acids can directly or indirectly in a plant’s physiological activities.
Amino acids are applied through foliar feeding, absorbed through the plant’s stomata or via the root area when incorporated into the soil. This also helps improve micro flora, which in turn, facilitates the nutrient assimilation.
The term auxin is derived from the Greek word auxein which means to grow. Compounds are generally considered auxins if they can be characterized by their ability to induce cell elongation in stems and otherwise resemble indoleacetic acid (the first auxin isolated) in physiological activity. Auxins usually affect other processes in addition to cell elongation of stem cells but this characteristic is considered critical of all auxins and thus “helps” define the hormone.
The following are some of the responses that auxin is known to cause
• Stimulates cell elongation
• Stimulates cell division in the cambium and, in combination with cytokinins in tissue culture
• Stimulates differentiation of phloem and xylem
• Stimulates root initiation on stem cuttings and lateral root development in tissue culture
• Mediates the tropistic response of bending in response to gravity and light
• The auxin supply from the apical bud suppresses growth of lateral buds
• Delays leaf senescence
• Can inhibit or promote (via ethylene stimulation) leaf and fruit abscission
• Can induce fruit setting and growth in some plants
• Involved in assimilate movement toward auxin possibly by an effect on phloem transport
• Delays fruit ripening
• Promotes flowering in Bromeliads
• Stimulates growth of flower parts
• Promotes (via ethylene production) femaleness in dioecious flowers
• Stimulates the production of ethylene at high concentrations
• Cytokinins are compounds with a structure resembling adenine which promote cell division and have other similar functions to kinetin. Kinetin was the first cytokinin discovered and so named because of the compounds ability to promote cytokinesis (cell division).
• Though it is a natural compound, It is not made in plants, and is therefore usually considered a “synthetic” cytokinin (meaning that the hormone is synthesized somewhere other than in a plant). The most common form of naturally occurring cytokinin in plants today is called zeatin which was isolated from corn (Zea mays).
A list of some of the known physiological effects caused by cytokinins are listed below. The response will vary depending on the type of cytokinin and plant species.
• Stimulates cell division.
• Stimulates morphogenesis (shoot initiation/bud formation) in tissue culture.
• Stimulates the growth of lateral buds-release of apical dominance.
• Stimulates leaf expansion resulting from cell enlargement.
• May enhance stomatal opening in some species.
• Promotes the conversion of etioplasts into chloroplasts via stimulation of chlorophyll synthesis.
• Gibberellins are classified on the basis of structure as well as function. All gibberellins are derived from the ent-gibberellane skeleton.
• The structure of this skeleton derivative along with the structure of a few of the active gibberellins are shown above. The gibberellins are named GA1….GAn in order of discovery.
• Gibberellic acid, which was the first gibberellin to be structurally characterised , is GA3. There are currently 136 GAs identified from plants, fungi and bacteria.
Dolomite: Soil conditioner
• Dolomite is natural soil conditioner and help stabilizing soil pH to optimum level as well as revitalize plant for maximum yield generation, better macro irrigation system and superior resistant against pest.
• Dolomite, a citric acid inherent properties is being used in agriculture to supply magnesium, MgO in place of kieserite via slow release (moisture reaction) method benefiting plants for long periods.
