INHIBITION OF WOUND INDUCED GLYCOALKALOID FORMATION IN POTATO TUBERS (Solanum tuberosum L.) BY ISOPROPYL‐N‐(3‐CHLOROPHENYL)‐CARBAMATE

摘要

ABSTRACTInhibitory effects of isopropyl‐N‐(3‐chlorophenyl)‐carbamate (CIPC), a sprout inhibitor, on wound induced glycoalkaloid formation of three cultivars of potato tubers were studied. Dipping of mechanically damaged Russet Burbank tubers and cut cubes in 100 and 1000 ppm CIPC emulsified water solution completely inhibited the wound induced glycoalkaloid formation. Dipping at 1 and 10 ppm CIPC resulted in 9–70 inhibition of glycoalkaloid formation. Fumigation of damaged Russet Burbank tubers and cut cubes with 100 and 1000 mg CIPC/m3caused 6–86 inhibition of wound induced glycoalkaloid formation. Fumigation at 10 mg CIPC/m3had no effect. CIPC has similar inhibitory effect of glycoalkaloid formation of damaged tubers of Red Pontiac and white Rose cultivars. CIPC treatment had no effect on existing glycoalkaloids and light induced glycoalkaloid formation pf po
