From: Characterization of sugarcane (Saccharum spp.) leaf senescence: implications for biofuel production
Three-dimensional plot of macronutrients content in the ‘between-leaves’ gradient and in the ‘in-leaf’ senescence gradient of the sugarcane cv. RB867515. Nitrogen (a), phosphorus (b), potassium (c), calcium (d), magnesium (e) and sulfur (f) were tested. The “leaf” axis represents the sugarcane leaves numbering system according to Kuijper [26]. Asterisk in the figure indicates statistical difference: **p ≤ 0.01, *p ≤ 0.05, and ns non-significant. The ANOVA and p values significant are available in the Additional file 2. DM dry mass
