| Summary: | Seasonal variations affect the rate of biomass accumulation in plants which is internally governed by biochemical metabolites. Studying the impact of atmospheric seasonal changes on biochemical parameters can improve our understanding of various plant species' physiological plasticity. Bamboos are a fast-growing group of woody grass species, widely distributed across tropical and sub-tropical regions of the world, and are an important species of the Indian subcontinent. Nevertheless, limited information is available on the seasonal response of biochemical's in bamboo species growing in ambient atmospheric circumstances. Therefore, we investigated the seasonal biochemical responses of Dendrocalamus strictus clones viz. Pantnagar (PNT) and Dhampur (DHM) to seasonal ambient atmospheric conditions. The concentrations of chlorophyll, protein, carbon, nitrogen, phosphorus, potassium, and magnesium in bamboo leaves were increased significantly (p < 0.025) in monsoon compared to summer and winter seasons. Carotenoid, total sugar and ascorbic acid contents were highest during winters and reduced significantly during monsoon. Proline content was highest in summer and reduced by 97% during monsoon, indicating effective adaptation to both clones' water-limited conditions. It was inferred that seasonal variation in atmospheric conditions significantly influenced the biochemical constituents of plants. This study provides a biochemical approach for screening potential bamboo species with adaptive nature for plantation purposes intended to mitigate climate change.
