Description

The plant growth regulative application of Paclobutrazol [ (2RS, 3RS) -1- (4-chlorophenyl) -4, 4-dimethyl-2- (1H-1, 2, 4-triazol-1-yl) pentan-3-ol] was investigated in several species of turfgrass (Table 1.) .<BR>Test plants of turfgrass are shown in table 2. It was observed thet the sensitivity of the plant growth retardants to the various kinds of turfgrass used in this experiment differs according to species.<BR>With a concentration of 10-4-10-3Mol. or above, Paclobutrazol showed a tendency to inhibit germination (table 3) .<BR>As concerns the effects of the Paclobutrazol treatment on the growth in elongation of the roots in the first stage of germination, it was discerned that it promoted an increase in the number of roots at a concentration of between 10-7Mol. and 10-11Mol. (Table 5) . In the case of a high concentration of 10-9Mol. or above, it showed a tendency to inhibit the growth in elongation of the turfgrass (Table 4) .
