Effect of accumulated degree-hours on shoot fate: field studies for Actinidia species. Genotypes are numbered as follows: A. indochinensis (1), A. polygama (2), A. purpurea (3), A. chinensis (4), A. arguta (5), A. deliciosa (6), A. latifolia (7), A. eriantha (8), A. guilinensis (9). Controlled environment datum for “Hayward” (10) is from Seleznyova and Halligan (2006). Each symbol represents the natural logarithm of the total proportion of terminated (short and medium) axillary shoots from eight parent canes. Line represents a linear model, y = Ax, r² = 0·74, slope P = 0·0027 (A. polygama and “Hayward” not included for model fitting).
