Plants adapt to climate change– researchers at Harvard are keen to know the real reason. Temperature irregularities have influenced many life forms greatly inclusive of plants and greens. Harvard researchers believe that many plants adapt to climate change strongly and thus, are carrying out studies on maple trees specifically. The two researchers namely Jake Grossman and Al Kovaleski carry out their studies in the area of Arboretum of Harvard University. And intend to know about how plants adapt to climate change by tracking the 60-million year evolution of maple trees. Maple trees originated in the east and now have a global presence, which certainly symbolizes some great form of adaptation.

Plants adapt to climate change-Cold Hardiness
“Cold hardiness” is a phenomenon with which, plants endure the chill of cold weather and scorch of the hot weather, explains these researchers. Harvard Gazette, conducted a dialogue with researchers to find out about their methodology for study and how plants adapt to climate change. Talking about evolution and adaptation, Grossman takes an instance of maple tree generations. A maple tree produces its very first daughter seed in about 10 to 30 years and maples have shown strong evolution for millions of generations. Thus, tracing back through these generations could also help researchers reach to grandmother of all maples, which in itself could be a great insight provider. Now, the difference in the temperatures of that time and the current time clearly shows the strong survival and evolution instincts of the maple breed.
Plants’ plasticity, climate change, and assisted migration:
Kovaleski talks about plasticity that makes plants adapt to climate change. He maintains that a lot of plants’ species adapt well to the changeability of the climatic conditions owing to this plasticity. But climatic stress has distressed umpteen number of plant species and has pushed them on the verge of losing this plasticity. Sadly enough, humans are oblivious to notice any such distressing changes in plants, but these need to be addressed at the earliest. Although, the detailed analysis of how plants adapt to climate change is for the year 2020 and the areas like New England, and the United States but phenomenon is generalized. Grossman talks about alleviating the climate change issue certainly by diminishing the carbon emissions, policy curating, and having sturdier plant species.
Assisted Migration:
An important procedure that researchers follow to help plants to adapt to climate change is “assisted migration”. They sow seeds or plant the plants’ saplings in the locations where they withstand the current temperature and also prepare themselves for future climatic changes. This gradually makes plants hardy enough to bear climatic fluctuations. Thus, the process of assisted migration is also intricately linked with the plasticity of plants.
Crossbreeding produces better crops and plants:
Cross-breeding is a tried and tested methodology adopted by conservationists, scientists and researchers worldwide. The plant of Southern high-bush blueberry is a classic example of hybrid and crossing populations. Well, the greatest advantage of the method is that it yields crops and plants that are better pest resistant, have better nutritional value, and also gives a greater produce. Now even for maple trees to produce a good quality and copious amount of syrup at a time, trees must be robust enough to endure extremely chilly nights and warmer days. Thus researcher is always on to produce a breed that not only gives syrup of premium quality but also yields great quantities. The aforementioned Harvard research shall also guide foresters, and organizers, to formalize, and prioritize plantation care.
Failing of a maple tree:
Researchers believe that as far as maple as a species is concerned, it is very unlikely to come to a sheer eradication in a short time. An individual tree on the contrary might die or fail under severe climatic stress or particular conditions. This would happen when the xylem, a complex tissue would fail to transport water to a maple tree’s branches and leaves, owing to the parched soil. And then the tree is likely to die to severe dryness and drought. But the extinction of an entire species is certainly an issue of hundreds and millions of years together unless humans exacerbate the climatic stress for plants. And that’s how smartly many species of plants adapt to climate change only to survive long enough.
