Role of genetic diversity and salicylic acid in drought stress memory of tall fescue.

ABSTRACT: Understanding the concequence of drought stress memory and its interaction with genetic diversity and pollination system is critical for improving resilience in turf and forage grasses like tall fescue. With global warming and the predicted occurrence of frequent drought stresses in the future, little is known about these effects, especially on morphological traits, physiological responses, root characteristics, and spectral reflectance indices (SRIs). This study addresses the knowledge gap by evaluating the effects of drought memory in tall fescue using four parental clones (two drought-sensitive and two drought-tolerant), which were manually controlled to produce four selfed (S₁) and four open-pollinated (OP) genotypes. Over two years, these genotypes were exposed to five mois
