Practical application of the phasic development theory

Let’s take a look at the practical conclusions that follow from the theory of phasic development.

For vernalization of potato tubers are germinated (shoots height — 2-3 mm) at a temperature of 12-15 °C; tubers thereafter for 20-25 days are kept at the same temperature in the light. To make better use of room space, string tubers on wire or twine and hang on special racks. After pre-etch twine by 2-percent solution of formalin. Before vernalization, etch potatoes by immersing it in bags of 0.5-percent formalin solution for 5 minutes. Tubers that passed vernalization process have a strong green shoots (up to 0.5 cm), around which are the root points (germs). Taken from http://worldofschool.org

Vernalization of winter wheat is not applicable in production, since thus they lose the frost resistance; in addition, it is inappropriate to reduce the winter crop as winter wheat in many areas more productive than spring wheat: they make better use of the moisture of autumn-winter precipitation. However, vernalization of winter wheat is used by breeders to produce three or four generations of plants per year, when grown in greenhouses.
