| Abstract: |
| Taking a potato（Solanum tuberosum L.）cultivar named Holand-212 as the material, different PGRs (plant growth regulators) were sprayed under the condition of field cultivation to study the regulatory effect of spraying of PGRs on the quality of potato tubers by comparing the activities of invertase and amylase, and the content of sucrose, starch, reduced sugar and vitamin C, etc. The results show that: Diethyl aminoethyl hexanoate (DTA-6) has great influence on the activities of invertase, the content of vitamin C and s
oluble protein, while the other treatments have mild regulatory effect on potato tubers at the growth period. For the purpose of tuber quality, SOD mimics (SODM) can significantly increase the content of starch and sugar content of tubers, significantly decrease the content of hydroxybenzene, soluble protein and vitamin; Choline chloride (Cc) can significantly increase the content of soluble protein and vitamin, significantly reduce the content of starch, hydroxybenzene and sugar; DTA-6 treatment has little effect on the quality of potato tubers. |
