Evaluating a Chlorophyll Content Meter on Three Coastal Wetland Plant Species
نویسنده
چکیده
The aim was to determine chlorophyll content index (CCI) and leaf chlorophyll (Chl a) content of a rush, Juncus roemerianus, a grass Spartina alterniflora, and a tree, Rhizophora mangle, occurring in coastal wetlands. Mean CCI values were 11.98 in J. roemerianus, 29.87 in S. alterniflora, and 30.68 in R. mangle. Mean chlorophyll content was 8.85 μg/cm in J. roemerianus, 9.72 μg/cm in S. alterniflora, and 4.68 μg/cm in R. mangle. Positive correlations between CCI and Chl a content were found for J. roemerianus (Chl a = 4.936 + 0.396 CCI), for S. alterniflora (Chl a = 3.429 + 0.208 CCI), and for R. mangle (Chl a = 1.406 + 0.099 CCI). The grass and mangrove with flat leaves showed better correlation between the CCI and Chl a content than the rush with cylindrical leaves.

Interand intra-site comparisons of the nitrogen (N) stable isotope composition of wetland plant species have been used to identify sources of N in coastal areas. In this study, we compared δ15N values from diff erent herbaceous wetland plants across 34 diff erent coastal wetlands from the fi ve main Hawaiian Islands and investigated relationships of δ15N with land use, human population density,...
متن کاملEvaluation of cement dust effects on soil microbial biomass and chlorophyll content of Triticum aestivum L. and Hordeum vulgare L.
ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...
متن کاملRethinking Chlorophyll Responses to Stress: Fluorescence and Reflectance Remote Sensing in a Coastal Environment
Chlorophyll fluorescence and hyperspectral reflectance were used to evaluate physiological responses to two common stressors in coastal environments. Chlorophyll content is one indicator of drought and salinity vegetation stress because of its direct role in the photosynthetic process and electron transport. Recent advances in fluorescence spectroscopy have led to the development of numerous re...

Phytoplankton species composition as well as amount of Chlorophyll-a and their relation to physico-chemical parameters were studied. The samples were collected monthly from October 1996 until September 1997 in two stations, i.e. Lavan and Douberkeh coastal waters. In this study, 65 phytoplankton species related to 3 groups of diatoms, dinoflagellats and Blue-Green Algae (24 genus and 44 species...
