a Distribution of lignin in developing culms of S. tootsik. Lignin content was determined by thioglycolic acid method [24]. See Table 1 for sampling details. b Rate of lignification in S. tootsik culms. Lignification rate (% d−1) was calculated as follows: v n = (C n+1 − C n )/(D n+1 − D n ), where v n is lignification rate of nth sampling, C n is average lignin content (%) of all internodes investigated at nth sampling, and D n is data of nth sampling. Data were plotted as (x, y) = (v n , D n ). Data are mean ± SD of three biological replicates
