Vernalization
Learninsta presents the core concepts of Biology with high-quality research papers and topical review articles. Vernalization Besides photoperiod certain plants require a low temperature exposure in their earlier stages for flowering. Many species of biennials and perennials are induced to flower by low temperature exposure (0°C to 5°C). This process is called Vernalization. … [Read more...] about Vernalization

Plant Growth Regulators Plant Growth Regulators (chemical messenger) are defined as organic substances which are synthesized in minute quantities in one part of the plant body and transported to another part where they influence specific physiological processes. … [Read more...] about Plant Growth Regulators
Characteristics of Growth
Learninsta presents the core concepts of Biology with high-quality research papers and topical review articles. Characteristics of Growth Growth increases in protoplasm at cellular level. Stem and roots are indeterminate in growth due to continuous cell division and is called open form of growth. The primary growth of the plant is due to the activity of apical … [Read more...] about Characteristics of Growth
