Deciphering the Germination Behavior of Sesame Cultivars: The Interplay of Hydrothermal Time Model Parameters and Seed Fatty Acid Profiles.

ABSTRACT: Seed germination is a critical developmental stage susceptible to environmental factors, such as temperature and soil water potential, which directly influence germination percentage and rate. To gain deeper insight into these interactions, this study re-analyzed data from a previously published germination experiment involving six distinct sesame (Sesamum indicum L.) cultivars with varied fatty acid profiles. Germination was recorded across eight constant temperatures (10-45 °C) and seven water potential levels (0 to -1.2 MPa), using thermal time, hydrotime, and hydrothermal time models. No germination occurred at -1.0 or -1.2 MPa. The highest thermal time constant, θT(g), was observed at -0.8 MPa across all cultivars, and germination rates declined as water potential decreased. Hi
