Ethylene is a gaseous plant hormone that plays a crucial role in the growth, development, and responses of plants to various environmental stimuli. It is involved in processes such as fruit ripening, flower senescence, leaf abscission, and response to stress. Here’s an overview of the roles of ethylene in plant growth and development: 1. Fruit […]

Gibberellins (GAs) are a class of plant hormones that play a fundamental role in regulating several aspects of plant growth and development. They are involved in processes such as stem elongation, seed germination, leaf expansion, flowering, and fruit development. Here’s an overview of the roles of gibberellins in plant growth and development: 1. Stem Elongation […]

Auxins are a class of plant hormones that play a fundamental role in various aspects of plant growth and development. They are involved in processes such as cell elongation, apical dominance, root initiation, vascular tissue differentiation, and tropisms (growth responses to external stimuli). Here’s an overview of the roles of auxins in plant growth and […]

Cytokinins are a class of plant hormones that play a crucial role in regulating various aspects of plant growth and development. They are involved in cell division, shoot and root growth, chloroplast development, delay of senescence (aging), and other physiological processes. Here’s an overview of the roles of cytokinins in plant growth and development: 1. […]

Brassinosteroids (BRs) are a class of plant hormones that play a significant role in various physiological processes, including cell elongation, cell division, seed germination, flowering, and stress tolerance. They are structurally similar to animal steroid hormones. The application of brassinosteroids in agriculture has been explored to enhance plant growth, stress tolerance, and overall crop productivity. […]

Bioinsecticides are natural insecticides derived from natural materials, organisms, or substances based on biological processes. They are a type of pest control method used in agriculture and gardening to manage and control insect pests in an eco-friendly and sustainable manner. Bioinsecticides offer an alternative to synthetic chemical insecticides, aiming to reduce the environmental impact and […]

Maintaining a healthy and vibrant turfgrass involves a combination of proper cultural practices, regular maintenance, and effective problem prevention and management. Here are the key secrets to achieving and sustaining a beautiful turfgrass: 1. Soil Preparation and Testing: 2. Proper Watering: 3. Regular Mowing: 4. Fertilization: 5. Overseeding and Reseeding: 6. Weed Control: 7. Pest […]

Biofortification is a strategy aimed at improving the nutritional content of food crops by increasing the levels of essential vitamins, minerals, and other nutrients through agronomic practices, conventional plant breeding, or biotechnology. The goal is to address micronutrient deficiencies, also known as hidden hunger, which is a widespread public health issue, especially in developing countries. […]

Induced Systemic Resistance (ISR) is another significant defense mechanism in plants, akin to Systemic Acquired Resistance (SAR). Both ISR and SAR are forms of induced systemic resistance, and they play essential roles in a plant’s ability to defend against pathogens. However, they differ in terms of their activation mechanisms and signaling pathways. Here’s a detailed […]

Systemic Acquired Resistance (SAR) is a crucial defense mechanism in plants that provides resistance against a wide range of pathogens, including bacteria, viruses, fungi, and other pests. SAR is a type of induced systemic resistance, which means that it’s activated throughout the entire plant following an initial localized exposure to a pathogen or its elicitors […]
