Cytokinin
Cytokinin is the dispatcher hormone that signals the hormone events controlling cell division and differentiation: • Cytokinin is primarily produced in root tip. • Cytokinin movement upward in the plant stimulates shoot formation and branching. • Cytokinin acts to...
Heat Blast on Canola
What is "Heat Blast"? Heat Blast is a combination of hot days (28ºC and up) and warm nights (16ºC and up). Canola generally relies on cooler nights to recover from the heat during the day, when the temperatures stay high at night this gives the canola no recovery...
What is Abiotic Stress?
Every seasoned producer knows there are a small number of factors in crop production that can be controlled, and a seemingly endless number of factors that cannot. Seed selection, timing of application, rate applied are all controllable decisions on the farm....
What are PGRs?
PGR stands for Plant Growth Regulator. Plant Growth Regulators (PGRs) are often known as plant hormones (also called phytohormones). They are signaling molecules produced within plants that occur in extremely low concentrations. Plant hormones control all aspects of...
Nutrient Hormone Interactions
Now that we have a baseline of knowledge in plant hormones, we will now discuss the interactions between different nutrients, and how those combinations influence the production of hormones within the plant. Plant hormone levels are also affected by nutrients:...
Abscisic Acid – The Terminator
Introduction to Plant Hormones: Abscisic Acid - The Terminator The final tour of the macro hormones brings us to Abscisic acid, the dormancy hormone. We will also discuss the importance for these hormones, to be in balance for full genetic expression in the plant....
Ethylene – The Regulator
Introduction to Plant Hormones: Ethylene - The Regulator Over the last three weeks we have gone over the macro-growth hormones, essential for the production of new cells and plant growth. This week and next week we will discuss the two macro-stress hormones: ethylene...
Gibberellic Acid – The Sizer
Introduction to Plant Hormones: Gibberellic Acid - The Sizer The past 2 weeks we feature the two other macro-growth hormones, Auxin and Cytokinin. This week we feature Gibberellic acid, the sizer. The interaction of these 3 hormones are essential to cell development,...
Auxin – The Activator
Introduction to Plant Hormones: Auxin - The Activator Continuing with our hormone feature, this week we highlight the activator hormone Auxin. One of the macro-growth hormones, Auxin, works with cytokinin and gibberellic acid as the foundational building blocks of new...
Cytokinin – The Dispatcher
Introduction to Plant Hormones: Cytokinin - The Dispatcher Plants have hormones just like humans. Plants produce and emit hormones based on the environment and physiological processes that are occurring at any given time throughout the plant life cycle. Each week we...
