Potassium Release and Seed Vigour in Germinating Bean (Phaseolus vulgaris L.) Seed as Influenced by Temperature over the Previous Five Generations

摘要: grown at each of the four temperatures for one generation, resulting in 16 lines. The latter treatment was called Final Temperature Treatment. seed examined using a test based on leaching potassium from imbibing seeds, which correlates better with field performance than germination tests. A also carried out. Seed weight decreased increasing Temperature, embryo unaffected, and Previous Treatment had no effect these parameters. little consistent K+ loss after 24 h or 72 leaching, but there large significant due to Leaching considerably less 27/22 °C lines, this unaffected by greatest cultivar Apollo. In Treatments inconsistent, cv. Apollo higher percentage high vigour seedlings By growing plants generations °C, produced greater potential vigour.
