Development of plants and its connection with the growth

The development of the plant is the way of the necessary qualitative changes of the cells’ content, which runs the plant from reproducing cell (zygote, spore, organism itself) to single or multiple formation of new reproductive cells.

Individual development of the plant, as well as its growth takes place in close cooperation with the environmental conditions.

Growth and development — are not identical processes. From the formulated definition of the development and growth, it is clear that the growth and development — are not equal phenomena. Differentiation of the concepts of growth and development has played a positive role. But, being not identical, growth and development, however, are closely connected with each other, and, of course, growth is one of the properties of the plants. Observed relations between the growth and the development stack in four cases:

  • rapid growth (increase in weight) and slow development, the slow movement of the plants to the seed formation;
  • slow growth and accelerated development;
  • rapid growth and rapid development;
  • slow growth and slow development.

From these actual cases, observed in nature, can be seen that the speed of development, i.e., flow rate of qualitative changes that lead to the formation of new seeds, depends not only on the speed of plant’s mass accumulation. There are cases when the plant accumulates a negligible amount of weight, but it moves quickly to the formation of flowers and seeds (diagram 208). For example, if the millet is sown in early spring, when the days are still relatively short, it will very soon throws a broom and begins to blossom. Taken from http://worldofschool.org

Diagram 208. Cotton. Plants were grown under different conditions. Left: rapid growth, but slow development (not yet in bloom). In the center: the rapid growth and rapid development (has formed flowers and capsules). Right: slow growth and rapid development (has formed flowers and capsules)

On the other hand, the Jerusalem artichoke or ornamental plant perilla that cultivates in gardens, do not bloom in the northern and middle belt of US because of too long duration of the day.

These examples are sufficient to show the differences between plant growth and development.
