Abstract
Primary roots of pea (Pisum sativum L. cv. Taichung No. 11) were treated with 0, 10 and 50 mg dm−3 paclobutrazol [(2RS, 3RS)-1-(4-chlorophenyl)-4, 4-dimethyl-2-(l,2,4-triazol-l-yl)pentan-3-ol] for 1 h at 48 h after germination. Paclobutrazol treatment inhibited root extension, promoted swelling (cell expansion was radial rather than longitudinal), and increased cell volume and the activity of catalase and peroxidase enzymes. Paclobutrazol also decreased root respiration and ethylene production. However, under non-stressed conditions, paclobutrazol treatment did not affect soluble carbohydrate content, water potential, osmotic potential or water loss. Under osmotic stress with polyethylene glycol (PEG), paclobutrazol diminished the increase of water potential and decreased the rate of water loss caused by the imposed stress, but had no effect on osmotic potential. Catalase and peroxidase activity were increased in osmotically-stressed roots of treated plants.
