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 to crop plants. Understanding and manipulating of plant genetics was in its heyday during the Green Revolution brought about by Norman Borlaug. During this time, the molecule of heredity, DNA, was also discovered, which allowed scientists to actually examine and manipulate genetic information directly. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains
