| Summary: | In the global warming scenario, temperatures are increasing specially in the Mediterranean area, where
pepper is grown. Pepper optimal temperatures range is 20 °C to 30 °C. When temperatures increase
above 32 °C pepper suffers fruit set damage that results in lower production. Grafting has been proven
an effective technique to overcome abiotic stresses. Hence suitable pepper rootstocks could be
employed to face heat stress. In previous studies, several pepper accessions were tested for heat stress
tolerance. In this experiment, the ungrafted variety (V) and the variety grafted onto tolerant (V/TR) and
sensitive (V/SR) pepper accessions were used to study heat stress alleviation strategies.
