Understanding Plant Growth Regulators Plant growth regulators (PGRs) are chemical compounds used to control plant growth and development. They can regulate processes such as flowering, rooting, and fruit development. These regulators are either naturally occurring or synthetic, with varied roles in enhancing plant health and productivity. The Role of Exogenous Application Exogenous application refers to … Read more
New research reveals how silicon-induced polyamines improve citrus growth and reduce oxidative stress under waterlogging conditions A breakthrough study published in Scientia Horticulturae sheds new light on the role of polyamines (PAs) and silicon nanoparticles (SiNPs) in helping citrus plants withstand waterlogging-induced hypoxic stress, a major concern in fruit crop production. Citrus plants, known for … Read more

Auxin-Like Substances Pioneered Parthenocarpic Fruit Development in Tomatoes Gustafson (1936) was a pioneer in demonstrating that applying auxin-like substances to the stigmas of tomatoes and other plants could induce parthenocarpy, leading to fruit development without fertilization. His subsequent work in 1937 further supported the idea that pollen grains contain plant hormones, likely auxins, which stimulate … Read more
Auxin and Gibberellins Introductions In plant biology, auxins and gibberellins are two hormones that play significant roles in various plant growth processes, including fruit set in tomatoes. Understanding how these hormones interact or cross-talk, provides valuable insights for agricultural practices that optimize crop yields. The Role of Auxin in Fruit Set Auxin, primarily synthesized in … Read more
Introduction to Reactive Oxygen Species (ROS) in Plants Reactive Oxygen Species (ROS) are a group of highly reactive molecules derived from the reduction of molecular oxygen. In the context of plant biology, ROS play a dual role, acting both as signaling molecules and as potential agents of cellular damage. The production of ROS in plants … Read more
Overview of Brassinosteroid Biosynthesis Brassinosteroids are a class of plant hormones that play a crucial role in regulating various physiological processes essential for plant growth and development.
