The physiological and phenotypic response of Salvia aethiopis L. to herbicides

Salvia aethiopis is an aromatic species within the Lamiaceae family, used both as a herb and ornamental plant, yield quality of which, when cultivated on commercial basis, frequently affected by weed infestation. Therefore, application herbicide often required for production this species. Considering current study, pot experiment based upon completely randomized design, with three replications, was conducted to evaluate physiological growth response S. five commonly herbicides (bentazon, phenmedipham/desmedipham, metribuzin, oxyfluorfen oxadiargyl). These were applied at concentrations (0.75X, 1X 1.25X where X equal recommended dose herbicide). The data obtained from demonstrated that led increase in crop damage, minimum fluorescence (F0) malondialdehyde content (MDA) concomitant decrease maximum quantum efficiency PSΙΙ (FV/FM), (FM), SPAD value, relative water (RWC), plant height shoot root dry weight compared control. However, level response/tolerance dependent specific applied. Of selected herbicides, S.aethiopis has shown display most tolerance bentazon. As such, these indicate tested, bentazon should be preferred broad leafed control, during
