Accurate assessment of seed quality is vital for predicting crop performance and ensuring optimal storage. We demonstrate and compare three distinct approaches for assessing the seed viability: 1. Tetrazolium (TZ) Test (Chemical/Quick Test): Learn how to use th

Original video: https://youtu.be/-l02lNP1pO4 Delivered on: 29 MARCH 2023 This video provides a comprehensive guide to seed viability testing using the tetrazolium test (TZ test), a rapid and reliable method for assessing seed quality. 🌿 We'll explore the science behind seed germination and demonstrate the step-by-step procedure for conducting the TZ test. The food for the germinating seedling may be stored in part of the embryo itself, such as the fleshy cotyledons of a be
