Tropofit

Tropofit - a variable climate plant, where periods of favorable conditions for plant growth occur cyclically. Tropophytes can survive both harsh winters and hot summer.

Tropophytes can survive unfavorable periods of development by adapting their habit and life activity to them. In cold and temperate climates, winter is unfavorable for plants, due to both low temperatures and physiological drought (when water is frozen, it is impossible to get water). For the winter, plants of this climate are retired. In warm climate areas, where drought prevails during the summer, cooler seasons are more favorable for plants, so the plants growing there go into a rest during a hot and dry summer.

Tropophytes adapt in different ways to cyclical seasonal changes. Some, called annual plants, only grow for a few months from spring to autumn, during which time they release seeds. Before winter they die, but their seeds survive, from which new plants grow in spring. Perennials overwinter in the form of rhizomes, tubers, bulbs or reduced aboveground leaf rosettes. The majority of perennial plants in temperate climate for the winter shed leaves, thus limiting transpiration, the buds of new leaves overwinter in buds, protected by scales. There are also fewer species of evergreen plants that do not drop leaves in autumn. They have xeromorphic leaves with a special structure. These include, for example, pin trees, various types of blueberries and others.
