Crescimento inicial de mudas de Schinus terebinhtifolius e do Phyllostachys aurea em vertissolos com diferentes características físicas e químicas

Abstract

The Vertisols are mineral soils clayey with high fertility, contain Horizonte Bv with typical features (slickensides); present handling difficulties, thus limiting the use by agriculture. The development of plant species in these soils can be quite variable due to variation of its physical and chemical characteristics, being a limiting factor to the development of plants in a Degraded Areas Recovery program. This study evaluated the effect of chemical and physical characteristics of two Vertisols in the initial development of two species bamboo (Phyllostachys aurea ex Carrière Rivière & C. Rivière) and mastic (Schinus terebinhtifolius Raddi). The study was conducted in a greenhouse in a randomized design factorial 2 X 2, with 6 repetitions. Were made biometric evaluations as height, stem diameter, number of leaves and chlorophyll a and b content of each plant. After 30 days, the plants were targeted in roots, stems and leaves and certain dry weight and nitrogen content. The soils were analyzed chemically and physically the end of the study. The mastic and bamboo plants showed differing performance when exposed to two Vertissolos with different properties.
