Abstract
Evidence relating improved performance of endophyte-infected perennial ryegrass during drought to plant physiological responses is equivocal. Hume et al. (1993) reported no effect of endophyte on ryegrass osmotic potential during moderate water deficit. Although evidence has shown that improved persistence of endophyte-infected tall fescue during drought is related to desirable physiological responses (West & Gwinn 1993) such evidence is sparse for ryegrass. This study aimed to compare physiological responses of “Grasslands Nui” (“Grasslands Pacific” for Exp. 2) ryegrass infected or free of “wild-type” Neotyphodium lolii endophyte, during water deficit.
