Intermediate disturbance hypothesis - Wikipedia

This is because the amounts of salt will stress the plant’s ability to maintain homeostasis, and plant growth will consequently be lower.

Plant senescence is the study of aging in plants. It is a heavily studied subject just as it is in the other kingdoms of life. Plants, just like other forms of organisms, seem to have both unintended and programmed aging. Leaf senescence is the cause of in deciduous trees.

The 1.78 cm decrease in the plants growth between the plants with 0 grams of salt added clearly proves that the hypothesis was correct.

There is a speculative on how and why a plant induces part of itself to die off. The theory holds that leaves and roots are routinely pruned off during the growing season whether they are annual or perennial. This is done mainly to mature leaves and roots and is for one of two reasons; either both the leaves and roots that are pruned are no longer efficient enough nutrient acquisition-wise or that energy and resources are needed in another part of the plant because that part of the plant is faltering in its resource acquisition.

Conversely, the perennial strategy may sometimes be the more effective survival strategy, because the plant has a every spring with growing points, roots, and stored energy that have survived through the winter. In trees for example, the structure can be built on year after year so that the tree and root structure can become larger, stronger, and capable of producing more fruit and seed than the year before, out-competing other plants for light, water, nutrients, and space.

The benefit of an annual strategy may be genetic diversity, as one set of genes does continue year after year, but a new mix is produced each year. Secondly, being annual may allow the plants a better survival strategy, since the plant can put most of its accumulated energy and resources into production rather than saving some for the plant to overwinter, which would limit seed production.

Some plants have evolved into , dying off at the end of each season and leaving seeds for the next, whereas closely related plants in the same family have evolved to live as . This may be a programmed "strategy" for the plants.
