Age- and genotype-specific circadian leaf movements in tomato and banana. Circadian rhythms of leaf pitch movements (θ_p) of (A) leaves of different ages of tomato plants (cv Ailsa Craig) at a different plant age (7 and 8 leaves on average) (n = 10) and (B) of leaves of different ages in three distinct tomato accessions (cv Ailsa Craig, Severianin and Cuba Plum) (n = 10). Leaf 4 was the oldest true leaf, followed by leaves 5 and 6. Shaded polygons represent the 90% confidence interval. C, Circadian rhythms of the pitch movement of the leaf petiole (θ_p) and midrib (θ_m) and the roll movement of the leaf lamina (ϕ_l) of single leaves of three banana genotypes (Leaf 3 M. balbisiana, Leaf 4 M. acuminata ssp. banksii, and Leaf 2 M. acuminata ssp. malaccensis). Data in (C) were centered to the starting angle. Lines in (A and B) represent average leaf angles ± the confidence interval. Shaded areas represent the dark period (12 PM to 8 AM for tomato (A and B), 7 PM to 7 AM for banana (C)).
