RT Journal Article SR Electronic T1 Changes in the Pattern of Isoperoxidases in the Dormant Canes of Thompson Seedless Grapes JF American Journal of Enology and Viticulture JO Am J Enol Vitic. FD American Society for Enology and Viticulture SP 137 OP 138 DO 10.5344/ajev.1978.29.2.137 VO 29 IS 2 A1 Kochhar, S. A1 Kochhar, V. K. A1 Khanduja, S. D. YR 1978 UL http://www.ajevonline.org/content/29/2/137.abstract AB Peroxidase activity was low in the canes of Thompson Seedless vines at mid-dormancy and increased considerably at bud burst. Increase was brought about earlier and was greater in thioureatreated canes than in untreated canes. Some isoperoxidases present during dormancy disappeared, and two new isoenzymes appeared with the break in dormancy. These isoenzymes appeared earlier in the thiourea-treated canes.
