Boron (B) is an essential micronutrient for plants, and it plays a crucial role in various aspects of plant growth and development, including pollen development and germination. Here’s an overview of the role of boron in pollen development and germination: 1. Pollen Development: 2. Pollen Germination: 3. Fertilization and Seed Formation: 4. Enzyme Activation and […]

The discovery of boron as an essential plant nutrient is a fascinating journey that began in the early 20th century. Here’s a historical overview of how boron’s significance as a plant nutrient was uncovered: 1. Early Observations and Plant Growth Studies: 2. Frank De Haan’s Research (1923): 3. Adolf Mehner’s Studies (1923): 4. Discovery and […]

Bacillus microorganisms, specifically certain strains of the genus Bacillus, are widely used in agriculture due to their beneficial effects on plants, soil, and pest management. These microorganisms offer a range of advantages and applications in sustainable and eco-friendly agricultural practices. Here are some key uses of Bacillus microorganisms in agriculture: 1. Biofertilizers: 2. Plant Growth […]

Beneficial microorganisms, often referred to as plant growth-promoting microorganisms (PGPM), play a crucial role in enhancing plant growth, nutrient availability, and overall soil health. These microorganisms can form symbiotic relationships with plants or directly influence soil conditions, leading to improved crop productivity and sustainability in agriculture. Here are various types of beneficial microorganisms and their […]

Silica (Si) is not considered an essential nutrient for all plants, but it is beneficial and plays a significant role in the growth and development of many plant species. Silica is primarily absorbed by plants in the form of silicic acid (Si(OH)4) through the roots. Once absorbed, it accumulates in plant tissues as amorphous silica, […]

Zinc (Zn) is an essential micronutrient for plants, meaning it’s required in smaller quantities compared to macronutrients but is equally vital for plant growth and development. Zinc is a cofactor for numerous enzymes and is involved in various physiological and biochemical processes within plants. It plays a critical role in many aspects of plant growth, […]

Plant essential nutrients are the elements or compounds that are necessary for the growth, development, and reproduction of plants. These nutrients are required in varying amounts and play vital roles in various physiological and biochemical processes within plants. Essential nutrients are usually categorized into two main groups based on the quantity in which plants need […]

Jasmonic and salicylic acids (JA and SA) are plant phytohormones that play key roles in resistance/tolerance to biotic and abiotic stresses and interact with the other families of phytohormones to modulate growth and development. Understanding these PGRs and their roles has given modern agriculture new tools to fight diseases and pests, reduce the build-up of […]

Brassinosteroids (BRs) are growth hormones from the steroid family that are found in all plant species. They have a high-growth promoting activity, particularly in pollen and anthers, and take their name from the pollen of canola (Brassica napus), where they were initially discovered. BRs are involved in the control of cell division, elongation and differentiation […]

Manganese (Mn) is an essential micronutrient that while needed in small amounts, plays a key role in photosynthesis. Mn sparks the photosynthesis process by splitting water after Photosytem II (PSII) fixes light to initiate the conversion of CO2 and water into carbohydrates. Manganese deficiency is widespread in Canadian Prairies and Eastern Canada, reducing growth and […]
