Hi Everyone! Welcome To My Channel Ali Academy Biology Lectures • About This Video ........................ • In This Video Lecture You Will Learn Basic Concept Of Vernalization • Vernalization • is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually flower. The term is sometimes used to refer to the need of herbal (non-woody) plants for a period of cold dormancy in order to produce new shoots and leaves, but this usage is discouraged. • Many plants grown in temperate climates require vernalization and must experience a period of low winter temperature to initiate or accelerate the flowering process. This ensures that reproductive development and seed production occurs in spring and winters, rather than in autumn. The needed cold is often expressed in chill hours. Typical vernalization temperatures are between 1 and 7 degrees Celsius (34 and 45 degrees Fahrenheit). • For many perennial plants, such as fruit tree species, a period of cold is needed first to induce dormancy and then later, after the requisite period of time, re-emerge from that dormancy prior to flowering. Many monocarpic winter annuals and biennials, including some ecotypes of Arabidopsis thaliana and winter cereals such as wheat, must go through a prolonged period of cold before flowering occurs. • About This Channel..................... • I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources. • One-stop destination for all biology lectures. • _ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial • _ The videos are categories under various heading to make the students life simplified • Visit My Other Channel Playlist ..................... • NMDCAT PART 1: • New 1st Year Biology • NMDCAT PART 2: • New 2nd Year Biology • Class 11th Lectures: • New 1st Year Biology • Class 12th Lectures: • New 2nd Year Biology • Class 10th Lectures: • • Matric Biology • Subscribe My Channel: • / aliacademya7r • Social Link........................ • Instagram: • https://instagram.com/ranaalibiologis...
