Evaluation of a portable chlorophyll meter to estimate chlorophyll and nitrogen contents in sugar maple (Acer saccharum Marsh.) leaves
Portable, non-destructive chlorophyll meters could be a valuable tool for forest managers and researchers. The ability of such meters to assess both chlorophyll and nitrogen content has been well established for many agricultural species, but not wellstudied for North American forest tree species. The objective of this study was to evaluate the ability of a portable chlorophyll meter to estimat...
متن کاملThe genetic diversity of forest tree species in French Guiana
The reproductive phenology of six tree species, Dicorynia guianensis , Vouacapoua americana , Eperua grandiflora , Carapa procera, Virola michelii and Chrysophyllum sanguinolentum, has been monitored in the Paracou stands over several years. A large variation of flowering rates exists among the species and from year to year. The tallest trees bloom and fruit more frequently than the smallest. T...
متن کاملAssessing Chlorophyll-a in the Southwestern Coastal Waters of the Caspian Sea
Caspian Sea with an average depth of 27m is the largest enclosed water body in the world. Despite its enormity and valuable biotic and economic resources, investigations on the biota and seawater properties are mosaic at best. In previous studies, the monitoring of the chlorophyll-a concentrations in the Southern Caspian Sea was organized based on satellite data sets however, vertical dis...

15 صفحه اولResponse of Chlorophyll, Carotenoid and SPAD-502 Measurement to Salinity and Nutrient Stress in Wheat (Triticum aestivum L.)
Abiotic stress can alter key physiological constituents and functions in green plants. Improving the capacity to monitor this response in a non-destructive manner is of considerable interest, as it would offer a direct means of initiating timely corrective action. Given the vital role that plant pigments play in the photosynthetic process and general plant physiological condition, their accurat...
