Description
This data was collected as part of the research on the drought and heat stress on the African eggplant to describe the effects of the stress combination on this crop. The data was collected at East Malling, UK, and comprises harvest data, physiological measurements, and nutritional quality data.

Data collection method
SPAD was measured three times a week at midday using a MultispeQ V2.0 device loaded with the Photosynthesis RIDES 2.0. Leaf expansion rate was collected 3 times a week by measuring by measuring the length and maximum width of two leaves. On the last day of the experiment, a leaf sub-sample representing a mix of developing and developed leaves was removed from the plant, placed in liquid nitrogen straight after recording its combined weight, and stored at -80°C for biochemical analysis. The rest of the leaves and stems were weighed separately, after measuring leaf number, stem diameter and plant height, and oven-dried at 80°C until reaching a constant weight. Leaf electrolyte leakage was recorded on the last day of the experiment by placing 5 leaf discs in distilled water and recording the electrical conductivity (EC1) of the solution 24 h after collection using a LAQUAtwin EC-33 meter (Horiba, Kyoto, Japan). A second measure (EC2) was taken after the discs were boiled for 60 min and EL = EC1/EC2. Leaf chlorophyll content was measured by placing 2 lif discs in 10 ml of cold ethanol and measuring the absorbance of the supernatant after 48 h (Ultrospe III, Pharmaci LKB). Calculation were based on the method described by Wintermans and De mots (1965). Total carbohydrates were measured following the method of Dubois et al. (1956) and total proteins following Bradford (1976). Total antioxidants were measured following the TEAC protocol of Re et al. (1999) and total phenols were measured following the method of Singleton et al. (1999). Leaf nutrient concentrations were measured in an ICP-MS following an acid digestion (Thermo-Fischer Scientifi iCAP-Q). A FlashEA 1112 elemental analyser was used for leaf nitrogen content.
