Abstract
Texas wintergrass (Stipa leucotricha Trin. & Rupr.) is an important cool-season, perennial forage grass in Texas. Seed handling problems and a limited knowledge of germination and establishment requirements have severely limited its use in revegetation programs. This study was designed to characterize floret morphology and investigate the effects of different temperature × water potential regimes on germination responses of chasmogamous and basal axillary cleistogamous florets from 2 Texas wintergrass populations in central Texas. Germination responses were evaluated at polyethylene glycol-induced water potentials of 0, -0.25, -0.50, -0.75, and -1.0 MPa under alternating temperature
