this work describes the establishment of procedures to induce in vitro callogenesis from Poincianellapyramidalis (Tul.) L. P. Queiroz, Fabaceae, explants. Nodal, internodal and leaf segments were iso-lated from in vitro germinated seedlings and cultured in MS medium with 0, 2.5, 5 and 10 mg l−1of2,4-dichlorophenoxyacetic acid. After 30 days, the explants with induced callus showed a quadraticresponse for the segments nodal, internodal and leaf, with increasing the callus formation in 2,4-dichlorophenoxyacetic acid concentrations of 6.28, 6.49 and 4.91 mg l−1, respectively. In 30 days there wasa linear oxidation rise with the increase to the 2,4-dichlorophenoxyacetic acid. After 60 days, oxidationvalues were minimum, at 2,4-dichlorophenoxyacetic acid concentrations of 5.13 mg l−1(internodal) and3.98 mg l−1(leaf). The highest callus production was observed after 30 days in the presence of 6.09 mg l−1,5.82 mg l−1and 4.91 mg l−1of 2,4-dichlorophenoxyacetic acid in nodal, internodal and leaf segments,respectively. After 60 days these segments showed peaks of production at 7.0 mg l−1(nodal), 6.15 mg l−1(internodal) and 5.08 mg l−1(leaf) of 2,4-dichlorophenoxyacetic acid. For callus induction the intake of2,4-dichlorophenoxyacetic acid was essential. The greater intensity in callus formation was observed in4.91 mg l−1in leaf segments after 30 days. |

Panicum maximum is important for cattle production in tropical regions, and it responds well to nitrogen (N) fertilization. Many cultivars have exhibited potential for use in silvopastoral systems, although there is limited information on how different levels of N can influence plant growth and nutritive value under shading. Morphogenetic and structural traits, biomass production and nutritive value of two P. maximum cultivars (Tanzania and Massai) were investigated under three shading levels (0, 37 and 58%) and four N rates (0, 50, 100 and 150 mg N dm3). Plants were grown in pots under shade. Leaf and stem elongation rate and leaf blade length increased with shading and in response to N. Tiller density was reduced with shading, but showed a linear increase fashion with N under full sun and moderate shading. Under intense shading, the tillering showed a quadratic response to N. Plant biomass production increased linearly with N under full sun and moderate shade, but it increased quadratically under intense shade. Crude protein (CP) content increased with shade and N and was greater for Tanzania than Massai under shade. Contents of NDF and ADF were greater for Massai than Tanzania. Acid detergent insoluble protein was reduced in Tanzania under shade, but it increased for Massai. It is suggested that the positive shading effect on CP content may not result in increased nutritional value. Although N fertilization was important for increasing biomass production under full sun and moderate shade, it should be avoided under intense shading.
