摘要：
The activity of a protein inhibitor of polygalacturonase (PIPG) was studied in potato tubers during storage and in potato leaves and stems during vegetation. The activity of PIPG in tubers varied between seasons. The activity of PIPG during dormancy changed depending on the storage stage and temperature. As a rule, it was higher in etiolated sprouts than in the tubers. The activity of PIPG was slightly higher in leaves of adult vegetating plants than in stems and decreased by the end of vegetation. These changes in the activity of PIPG are suggested to be associated with changes in the growth rate.
