Snow pea relationship—and are therefore a useful companion plant, especially useful to grow intercropped with green, leafy vegetables that benefit from high nitrogen content in their soil. Snow peas can be grown in open fields during cool seasons and can thus be cultivated during winter and spring seasons. Storage of the pea with films of polymethylpentene at a temperature of 5 °C and a concentration of oxygen and carbon dioxide of 5 kPa augments the shelf life, internal and external characteristics of the plant. Austrian scientist and monk Gregor Mendel used peas which he called "Pisum saccharatum" in his famous experiments demonstrating
Plant genetics an English translation. Mendel died in 1884. The significance of Mendel's work was not recognized until the turn of the 20th century. Its rediscovery prompted the foundation of modern genetics. His discoveries, deduction of segregation ratios, and subsequent laws have not only been used in research to gain a better understanding of plant genetics, but also play a large role in plant breeding. Mendel's works along with the works of Charles Darwin and Alfred Wallace on selection provided the basis for much of genetics as a discipline. In the early 1900s, botanists and statisticians began to examine the segregation ratios
