Chinese study finds aromas help plants resist cold weather
Aromatic plants not only have a sweet smell but also a strong tolerance to cold weather. A new Chinese study found that adding a floral scent to tea plants may help them withstand low temperatures.
Cold weather is an environmental stress factor that can limit the distribution, survival and growth of various plants. According to the study published in the scientific journal New Phytologist, increasing the concentration of aromatic substances in tea plants can enhance their resistance to cold temperatures.
Researchers from east China's Anhui Agriculture University have discovered that nerolidol, an aromatic substance accumulated in tea plants in cold weather, can be converted into a type of glucose by a key gene UGT91Q2. This type of glucose feeds the plant and is gradually converted into other nutrients that promotes plant survival and growth when the temperature drops, subsequently enhancing the plant's cold tolerance.
Song Chuankui, lead researcher, said the discovery of plants' cold resistance might have significant potential applications in the food and cosmetics sectors.
