Title: Seedling growth of understorey species of a southeast Brazilian tropical forest
Author: Valio, IFM
Abstract: Thirteen understorey species of a mesophyllous tropical forest were studied tinder two different photosynthetic photon flux densities (PPFD). Seedlings were grown in the glasshouse tinder 51% and 2.6% solar PPFD. Growth of the seedlings was evaluated by 1-) total height; 2-) leaf number; 3-) leaf dry mass; 4-) stem dry mass; 5-) root dry mass: 6-) stein length/mass; 7-) shoot/root mass; 8-) percent allocation to leaf stein and roots. For most of the parameters recorded, low PPFD drastically reduced growth. It seemed that the strategy of these understorey species was a reduction of growth under low PPFD saving energy for survival.
