Influence of photosynthetic photon flux density on growth and transpiration in seedlings of Fagus sylvatica.
Beech seedlings (Fagus sylvatica L.) were grown in various combinations of three photosynthetic photon flux densities (PPFD, 0.7, 7.3 or 14.5 mol m(-2) day(-1)) for two years in a controlled environmental chamber. Dry mass of leaves, stem and roots, leaf area and number of leaves, and unit leaf rate were affected by both previous-year and current-year PPFD. Number of shoots and length of the ma...
متن کاملInfluence of site conditions on the survival of Fagus sylvatica seedlings in an old-growth beech forest
Following a full mast production in autumn 1995 in the old growth beech forest of la Tillaie, France, cupules, live and dead yearling seedlings were counted in September 1996 in 40 plots, embracing a wide range of ecological conditions. The influence of geomorphology and forest stage on mast production and on seedling establishment and survival was studied. Maximum seedling abundance did not oc...
متن کاملEffect of photosynthetic photon flux density on carboxylation efficiency.
The effect of photosynthetic photon flux density (PPFD) on photosynthetic response (A) to CO(2) partial pressures between 35 pascals and CO(2) compensation point (Gamma) was investigated, especially below PPFD saturation. Spinacia oleracea cv ;Atlanta,' Glycine max cv ;Clark,' and Arbutus unedo were studied in detail. The initial slope of the photosynthetic response to CO(2) ( partial different...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
15 صفحه اولPhotosynthetic Photon Flux Density, Carbon Dioxide Concentration and Temperature Influence Photosynthesis in Crotalaria Species
Crotalarias are tropical legumes grown as cover crops or as green manure to improve soil fertility. As an understory plant in plantation systems, these cover crops receive low levels of irradiance and are subjected to elevated levels of CO2 and temperatures. A greenhouse experiment was conducted to evaluate the independent short-term effects of photosynthetic photon flux density (PPFD), externa...
