Alkalitrophy – Definition & Meaning

Alkalitrophy is a term used to describe the growth of plants in alkaline soils. This condition can be challenging for many plants, as the high pH levels can limit nutrient uptake and cause toxicity. In this article, we will explore the definition and meaning of alkalitrophy, its origin, associations, synonyms, antonyms, and example sentences.


Alkalitrophy is defined as the ability of plants to grow in alkaline soils with a pH of 7.5 or higher. This condition is often associated with arid and semi-arid regions where rainfall is low, and the soil is naturally alkaline.


The term alkalitrophy is derived from the Greek words “alkali” meaning “salt” and “trophos” meaning “nourishment.” The condition was first described by botanists in the early 20th century who noticed that certain plants could thrive in alkaline soils.

Meaning in different dictionaries

The term alkalitrophy is not commonly found in most dictionaries. However, some online dictionaries define it as the ability of plants to grow in alkaline soils. Other dictionaries may not have an entry for the term.


Alkalitrophy is often associated with plants that are adapted to arid and semi-arid environments. These plants have evolved to tolerate high pH levels and low nutrient availability. Some examples of plants that exhibit alkalitrophy include cacti, succulents, and certain grasses.


There are several synonyms for alkalitrophy, including alkaline tolerance, alkali resistance, and alkaline adaptation. These terms all refer to the ability of plants to grow in alkaline soils.


The antonyms of alkalitrophy are acidotrophy and acid tolerance. These terms describe the ability of plants to grow in acidic soils with a pH of 5.5 or lower.

The same root words

The root words of alkalitrophy are “alkali” and “trophos.” Other words that share these roots include alkaline, alkali metal, trophic level, and trophoblast.

Example Sentences

  1. The cactus is an excellent example of a plant that exhibits alkalitrophy, as it can grow in the alkaline soils of the desert.
  2. Some plants have developed unique adaptations to survive in alkaline soils, such as the ability to store water in their leaves or roots.
  3. Farmers in arid regions often struggle with alkalitrophy, as the high pH levels can limit crop yields and nutrient uptake.
  4. Researchers are studying the genetic mechanisms behind alkalitrophy in hopes of developing more alkaline-tolerant crops for agricultural use.
