Drought deciduous

In botany, deciduous is a description of plants that carry out a process which lead to the loss of leaves during a certain time annually.

Cold deciduous plant species focus on conserving its nutrient to survive through the extreme conditions in winter.

Conversely, evergreen plant species carry out abscission in a smaller scale continuously in any seasons throughout the year.

Mechanisms that trigger leaf drop is a process which includes physiological and chemical pathways happening within the plants.

Carotenoids are the pigmentation that is responsible for the yellow or brown colour of the leaves as they started to lose the presence of chlorophyll.

Deciduous plant will undergo the process of abscission either seasonally or due to external stress caused by the environment.

Many deciduous plant species make use of their leafless period efficiently by triggering reproductive processes such as flowering.

[9] One of the most differentiating characteristics of these plants is featuring roots that penetrate much deeper into the ground[10] allowing evergreens to gain access to water source from underground and survive through a dry season.

[11] Plant species that possess features that appear to be in between of evergreens and deciduous can be categorised as semi-deciduous, semi-evergreen depending on their annual abscission and flowering patterns.

[13] Deciduous plants have a higher photochemical efficiency when compared to evergreen species during times when it has leaves during spring and summer.

[16] Drought deciduous plants species are often found in SAST ecosystems as they have higher tolerance to unpredicted external stress factors.

Drought deciduous plants are very commonly found near the borders of deserts or along the coastal areas in the Northern Americas.
