【摘要】 |
|
The effects of regulators on the respiratory enzymes of Qiyuesu’s pear branches during dormant period were studied. The results showed that enzyme activities of SDH, G-6-PDH and 6-PGDH were increased by 0.02？mmol/L SA and 120？mg/L GA3. The enzyme activities of phosphohexoisomerase were reduced by 0.02？mmol/L SA and 120？mg/L GA3. Compared with the control, the PGI activity was reduced by 20.5% and 13.6% using 0.02？mmol/L SA and 120？mg/L GA3. Similarly, the SDH activity was increased by 6.1% and 29.2%, respectively. Likewise, the activity of G-6-PDH and 6-PGDH was increased by 93.9% and 24.8%. Changes of respiratory enzymes were consistent with respiratory pathway of regulators, which indicated that SA and GA3 were helpful to break the dormancy by enhancing activities of SDH, G-6-PDH and 6-PGDH. |
