e1“The effects of water deficits on plant morphology and biochemistry were analyzed in two photoperiodic strains of field-grown cotton (Gossypium hirsutum L.)”
e3“Gross photosynthesis decreased from 0.81 to 0.47 milligram CO(2) fixed per meter per second and the average midday water, osmotic, and turgor potentials decreased to -2.1, -2.4, and 0.3 megapascals, respectively”

- Intervention effect Paraquat resistance decreased in cotton strain T25 following irrigation.
- Intervention effect Glutathione reductase activities remained elevated in cotton strains T25 and T185 after the irrigation treatment.
