MORPHOANATOMY LEAF OF CUPUASSU PLANT ESTABLISHED FOR DIFERENT METHODS OF SPREAD AND SHADOWING

ABSTRACT

The objective of this study was to evaluate the effect of shadowing and propagation methods in morphoanatomy and establishing cupuassu. The field experiment was conducted in a randomized complete block design with four replications of 10 plants each. For growth analysis was used to plot sub - divided (five times - plot, three levels of shading - subplot and four methods of propagation - sub - subplots). For evaluation of biometrics plant was used scheme subdivides plot with shading in the plot and subplots propagation methods; and the analysis morphoanatomic considered the randomization in blocks of shading. Analyses of growth were performed every 90 days and morphoanatomical at 15 months after planting. The thickness of the spongy parenchyma was higher in shaded leaves by 50 % screen; other features morphoanatomic suffered no significant influence of shading levels. Seedlings with initial development in nurseries reached higher relative growth rate and absolute. The highest relative growth rates and absolute were obtained in culture under 50 % screen, followed by the consortium (45 %). The worst performers in all traits were observed in plants grown in full sun.
