Abstract

In this paper the authors present the results of the effect of the macronutrients nitrogen, phosphorus and potassium in the increase of fiber length and the thickness of the cell wall in Pinnus elliottii. The statistical analyses shows that higher levels of N seemed to decrease both length of fiber elements and the thickness of the wall. The effect of P and K were not well defined.
