Resumo: Lianas são dominantes em clareiras naturais ou originadas por ação antrópica e tal distribuição nos dá indícios que esta forma de vida necessita de alta irradiância para o seu crescimento e desenvolvimento. Lianas enraízam-se no solo e usam outras plantas, especialmente árvores para o seu... Ver mais
Abstract: The lianas are copious in natural and man-made clearings and it appears that these forms of life require high irradiance for development and growth. Lianas are rooted in the soil and use other plants, especially trees as support. Since these plants begin their growth on the forest floor,... Ver mais
ar red, with responses that included reductions in leaf area and leaf number, increases in petiole length, reductions in specific leaf area and leaf area ratio when compared with plants growing in neutral shade (i.e. shade without altered quality). Also, a shift in allocation to stem mass over leaf... Ver mais

ar-red in Canavalia. Gouania showed significantly greater growth in height that was paralleled with increases in internode length under shade with low red

ar-red at 1,8% of PAR, but patterns of allocation were not affected by altered spectral quality. Under natural conditions (closed canopy and clearings), Canavalia responded to deep shade with characteristics that promoted increases in photosynthetic tissues in detriment to support tissues, for...

These two lianas species are found in places of high irradiance e.g. Forest edge, but this specific... Ver mais
