Climate Change causing Flowers To Change Their Colors

It is observed that many life forms have adapted new faces and colors or changed in consequence of Climate change.  Climate change has effectively influenced biological lives. Plants and flowers are going to change their colors. This seems exciting about the changing of colors but who knows,  it’s going to badly impact the flowers’ life. Global warming and depletion of ozone is a major reality about today’s climate. Depletion of ozone causes excessive UV radiation on Earth. This has affected the ecological world. Flowers have changed colors in response to the excessive UV radiation. This has gradually impacted the nature of plants and flowers.

Ozone Depletion Impact on Climate Change

Ozone is a layer of gaseous molecules. It is found in Earth’s stratosphere, located between 12 to 50 kilometers above the earth’s surface. This absorbs UV radiation coming from the sun to earth. The amount of Ozone has been rapidly decreasing in the earth’s atmosphere since 1970. So that plants are more exposed to UV radiations than ever before. Recent research about the penetration of UV radiation in plants tissues declared that plants undergo internal anatomical and pigmentation changes. Similarly, these changes result in different plant responses in the form of UV pigments. Climate change is also due to this extra UV radiation on earth. Simply the plants need sunlight to grow but excessive sunlight will surely have a negative impact on them. 

Research On Flowers’ Pigmentation 

According to the research of scientists from  Clemson University, flowers have been changing their colors of petals during the past 75 years. This is due to the rising temperatures and altering UV radiations. He researched about 1200 plant specimens, with 42 different species from three continents. He analyzed between 1947 to 2017, using UV-sensitive cameras. Then he checked out the level of floral pigmentation of these specimens. The results showed that changes in floral pigmentation accelerated after the latter half of the 20th century. Moreover, the average changes in flower petals occurred about 2% each year from the past seven decades. However, the rising temperatures and ozone depletion is continuously increasing levels of pigmentation in plants for no reason. 

Changing in Plants and Flowers 

Two of the flower species ( A-C and D-F ) exhibited varied floral pigmentation. Higher UV radiation formed a darker color of petals. These changes could not be clearly visible to the human eye. All the petals are not equally affected but some. 

Flowers have undergone significant change due to the environmental effects. Also, the flowers may not look totally different. Among the tested, most of them exhibit reduced plant growth (reduced in height, dry weight, leaf area, etc.), photosynthetic functionality, and flowering. Photosynthetic functionality could be reduced due to the immediate effects on the metabolic system in plants, or indirectly on stomatal function.

Plants may also respond by accumulating UV-absorbing compounds in their outer tissue layers. In a recent study, Brassica campestris found to be more sensitive to UV radiation,it will have increased leaf thickness by 45% as well as increasing UV-B screening pigments by 21% relative to controls. Part of chlorophyll  (per leaf area) measured as chlorophyll fluorescence, would be decreased. 

According to the research of Barnes in 1990 the enhanced UV-B radiation can cause changes in the growth form of plants without necessarily decreasing plant production. These changes include reduced leaf length, increased branching, an increased number of leaves. 

No doubt the flowers are the beauty of the planet. They have a great impact on human life. The different colors of flowers mean different feelings to the human mood. The red color of the rose keeps different meanings than a yellow rose. Yellow roses are believed to be given to friends while red roses are for loved ones. The changing and damage of these colors will have a lot of impact on the planet.
