Abstract excerpt

BACKGROUND: Pepper (Capsicum annuum L.) holds significant global importance as both a spice and a vegetable, extensively cultivated for its unique pungency, nutritional value, and diverse pharmaceutical uses. Being a warm tropical fruit vegetable, it is highly sensitive to heat stress (HS). However, temperature above 33 °C impairs its reproduction, subsequently impacting fruit yield and seed quality. Despite this...
