Table 1. Eight parameters that describe when and where the stem bends. We note that the threshold κ_c=−0.04 for t_start^κ=min and s_start^κ=min is introduced to avoid fluctuation in κ=min being insensitive with −0.05, −0.06.

Quantity	Explanation	Range of values
t_start^θ=π/4	The first time when any position reaches θ=π/4	60–70
s_start^θ=π/4	The curvilinear coordinate of the position that first reaches θ=π/4	0.40–0.65
s^θ=π/4_300 min	The curvilinear coordinate of the position s (θ=π/4) at t=300 min	0.20–0.40
α′	The slope of (s/L₀, t) with 5 time points from time t_start^θ=π/4	−300–−1,200
t_start^κ=min	The first time when any position reaches κ<κ_c	40–70
s_start^κ=min	The curvilinear coordinate of the position that first reaches κ<κ_c	0.55–0.65
s^κ=min_300 min	The curvilinear coordinate of the position s (κ=min) at t=300 min	0.15–0.40
β′	The slope of (s, t) with 5 time points from time t_start^κ=min	−1,200–0
