Fig. 1From: Hydrogen cyanamide breaks grapevine bud dormancy in the summer through transient activation of gene expression and accumulation of reactive oxygen and nitrogen speciesMorphological and anatomical changes in grapevine buds during dormancy break. Percentages of budbreak after 192 h of treatment with P, HC, PHC, or water as a control (n = 10, bar: standard deviation) (A). Changes in bud length after PHC treatment at 0, 6, 12, 24, 48, 96 and 192 h (n = 10, bar: standard error) (B). Longitudinal sections of grapevine floral bud development during release of dormancy after PHC treatment: (a) 0 h, (b) 6 h, (c) 12 h, (d) 24 h, (e) 48 h and (f) 96 h. ip: inflorescence primordium (C).
