Abstract
Objetivou-se com este trabalho avaliar o desenvolvimento das mudas de Schinus terebinthifolius e Clitoria fairchildiana sob condiç��es de sombreamento e pleno sol. As mudas foram cultivadas sob sombrites de 70% e 50% de luz e sob luz plena. O experimento foi conduzido em DBC com 4 repetições de 20 mudas. Foram avaliados a altura do caule e o diâmetro do colo a cada vinte e um dias. Ao final do experimento foram realizadas as avaliações de peso seco total (PST-g), área foliar (AF-dm²), razão de peso foliar (RPF -g/g); e peso específico de folha (PEF -g/ dm²). As sementes de aroeira do campo e do sombreiro apresentaram 70% e 85% de germinação, respectivamente. S.terebinthifolius tolera bem um sombreamento moderado (70% de luz), sendo seu cultivo a pleno sol o mais indicado, pois é quando as mudas atingem menor altura (32,93 cm), diâmetro médio de 7,15 mm, maior PST (74,66 g); menor PEF (0,025); as mudas de C.fairchildiana sob condições de pleno sol não se desenvolveram satisfatoriamente, embora a altura não tenha variado entre os níveis de luz (16,39 cm), apresentaram menor diâmetro (5,32 mm), menor PST (26,22 g), menor AF (32,98 dm²) e maior PEF (0,4).
The objective of this work was to evaluate the development of S. terebinthifolius and C. fairchildiana seedlings under shade and full sunlight conditions. The seedlings were cultivated under 70% and 50% sunlight and full sunlight. The experiment was carried out in a randomized block design with four replications of twenty seedlings. Stem height and collar diameter were evaluated every 21 days. At the end of the experiment total dried weight (TDW-g), leaf area (LA-dm²), leaf weight rate LWR-g/g) and leaf specific weight (LSW-g/dm²) were also evaluated. The seeds of S.terebinthifolius and C. fairchildiana showed a germination of 70% and 85% respectively. S. terebinthifolius tolerated moderate shade (70% sunligth) however, full sunlight seemed to be most appropriate. C. fairchildiana seedlings did not develop in a satisfactory manner under full sunlight. Although the stem height did not vary among light levels (16.39 cm), the seedlings showed lower diameter (5.32mm), lower total dried weight (26.22), lower leaf area (32.98 dm²) and higher leaf specific weight (0.4).
