Elevated temperature and carbon dioxide alters growth and leaf-chemical composition in two important neotropical crops, Coffee (Coffea arabica) and Cacao (Theobroma cacao)

This dataset contains data collected from a 6 month climate-controlled glasshouse experiment using coffee (Coffea arabica) and cacao (Theobroma cacao) seedlings subject to increases in temperature in the presence and absence of elevated [CO2]. Seedlings of each species were subject to temperatures of ambient +4 degrees celcius and increased [CO2] levels of 800ppm. Observations were taken throughout the duration of their growth, with destructive harvests occurring prior to treatment exposure, and at two subsequent harvest dates. By measuring parameters of height, partitioned biomass, gas exchange, leaf chemical compound composition and more, this dataset allows exploration of the effects and possible interactions of elevated temperature and increased [CO2] on the early growth, physiology and biochemistry these species. , Planting Material and Growing Conditions
Coffee (Coffea arabica L., Rubiaceae, cv. Bourbon) saplings (n = 100, approximately 3 months old), grown in plastic planting tubes (50 x 50 mm at top, 120 mm tall, 250 ml volume) were obtained from the Skybury nursery in the Atherton Tablelands. The saplings were grown from seeds planted in late August 2016 and had received only water during their development. Sixty coffee saplings, selected for physical homogeneity, were transplanted into 25 L pots on 3 December 2016, and each provided with 500 mL of liquid seaweed fertilizer (Seasol®) to reduce possible transplanting shock. Cacao (Theobroma cacao L., Malvaceae) seeds were obtained from the Goodman Cacao Estate in Killaloe, North Queensland, Australia. Ten ripe cacao pods were harvested from a single cacao tree (SG2 hybrid variety, Papua New Guinea origin), the seeds were extracted, de-pulped, and primed in water for 24 hours. Large, round and healthy seeds were planted into 25 L pots (n = 60) o..., , # Elevated temperature and carbon dioxide alters growth and leaf-chemical composition in two important neotropical crops, coffee (Coffea arabica) and cacao (Theobroma cacao)

## Description of the data and file structure

Five separate .csv files are provided describing growth, biomass partitioning, gas exchange, and leaf biochemistry in the studies coffee and cacao seedlings. These data were collected from a 6 month climate-controlled glasshouse experiment using coffee (Coffea arabica) and cacao (Theobroma cacao) seedlings subject to increases in temperature in the presence and absence of elevated [CO2]. Seedlings of each species were subject to temperatures of ambient +4 degrees celcius and increased [CO2] levels of 800ppm. Observations were taken throughout the duration of their early growth stages, with destructive harvests occurring prior to treatment exposure, and at two subsequent harvest dates a..., , **Changes after Oct 3, 2024:** Missing phenolics data set (Phenolic_Data.csv) has now been added.
