Kinetics of latex yeild (a), duration of latex flow (b), plugging index (c), TSC (d), sucrose content (e) and RSH content (f) in the latex of the mature virgin rubber trees treated with ethephon.

<p>The latex yeild and physiological parameters i.e., duration of latex flow, TSC, plugging index, sucrose content and RSH content were measured at 0, 8, 24 and 48 h after ethephon treatment. The values were shown as the means ± standard deviation (n = 3) for each including six trees. One-way ANOVA was performed using SPSS 19.0 software. The Student–Newman–Keuls test was used for multiple comparisons testing to investigate the significant differences between groups. Bars with different letters were significantly different at the <i>p</i> < 0.05 level.</p>
