(agricultural Wealth Network) one is the physiological effect. The photosynthetic rate of treated leaves, petioles and shrinking stems increased by 30.8%. The gibberellin content in the plant decreased and the abscisic acid content increased, indicating that the plant growth was inhibited. The second is the biological effect. The rapeseed stem treated with paclobutrazol has strong dwarf root, the length control rate of the shrinking stem segment is up to 362%, the rhizome diameter and root dry weight are increased by 15% and 36% respectively, and the leaf has compact tissue structure and strong drought resistance. The rape seedlings cultivated with paclobutrazol survived quickly and developed early. The third is the yield effect. Rape was treated with paclobutrazol to increase the yield by 10% to 20%, and more than 30% in the year of severe freezing injury.
