Abstract
Abstract: The impact of elevated CO2 (eCO2 ) and elevated temperature (eT) on growth, phenology, yield, and quality has been widely investigated in field crops, but limited work has been done so far on the combined effect of eCO2 and eT on medicinal plants. Hence, a 2-year experiment was conducted at CSIR-Institute of Himalayan Bioresource Technology, Palampur, India, to study plant growth, biomass, and essential oil composition of mushkbala (Valeriana jatamansiJones) in response to elevated CO2 , temperature, and their combination with the regulation of fertilization. The growth and yield of V. jatamansiwere significantly affected by environmental conditions and fertilization. Root length and root volume were 16.85 and 48.99% higher in the combined eCO2 and eT conditions compared to the ambient conditions. Combined eCO2 and eT showed more positive effect on the stem, root and aboveground biomass as compared to leaf, and flower biomass, over the years. Fertilization improved the growth and biomass of plants compared to unfertilized pots. FACE + FATI positively affected V. jatamansi’s major essential oil compound patchouli alcohol, while fertilization showed a negative effect. Our results highlight the need for long-term studies on medicinal and aromatic plants due to changes in the growth and efficiency of crop. Graphic abstract: ![]()
