Bryophyte phytomass in tropical ecosystems

Botanical Journal of the Linnean Society, 1990
Knowledge about bryophyte production and phytomass in the tropics is poor and has been derived principally from studies of epiphytic bryophytes. Such work has been undertaken in Transvaal, Tanzania, Venezuela, Peru and Borneo. Except for the studies in Peru and Borneo, the vegetation types studied and the methods used have been too variable to allow ...

An assessment of the aboveground phytomass and carbon levels of the forests of northern Telangana, India, using a geospatial technique

, 2020
An assessment of aboveground phytomass and carbon levels was conducted in the South-Central region of India, in the Telangana State, situated on the high Deccan Plateau. The study is based on field observations at 30 sites using cluster sampling.

Trophic Exploitation and Arctic Phytomass Patterns

The American Naturalist, 1983
Aboveground phytomasses of tundra communities and changes in moss phytomass after a lemming peak were reviewed to test the prediction of the hypothesis of exploitation ecosystems that herbivory limits the aboveground phytomasses of moderately unproductive plant communities.

Phytomass, Seasonal Phenology and Photosynthetic Studies

1982
The ultimate objective of the projects concerned with plant growth is the measurement of net primary production (NPP), ie that part of the total or gross primary productivity (GPP) of the photosynthetic plants remaining after the photosynthate has been utilized in respiration of these plants.

Analysis of Phytomass Yield in Wheat

Agronomy Journal, 1992
AbstractGrain yield (GRY) increases in wheat (Triticum aestivum L.) have been achieved through increases in harvest index (HI). Further improvements in HI appear difficult so further increases in GRY may have to come through increases in phytomass yield (PMY). Increases in PMY also should increase yield of nongrain plant parts (NGRY) which is important

Above Ground Forest Phytomass Assessment in Southern Gujarat

Journal of the Indian Society of Remote Sensing, 2011
Spectral modeling of above ground biomass (AGB) with field data collected in 48 field sites representing moist deciduous forest in Surat district is reported. Models were generated using LISS-III and MODIS data. The plot-wise field data was aggregated to MODIS pixel (250 m) using area weightages of forest/vegetation. The study reports that above ground

Comparing nondestructive measures of forage structure and phytomass

Canadian Journal of Plant Science, 2000
Nondestructive radiative transfer and canopy volume methods were compared with the destructive hand-clipping method to determine forage structure and phytomass. On a native range site, fifteen 1-m2 circular plots were located at each of five microsites. On a crested wheatgrass site, thirty 1-m2 plots were located in grazed and in ungrazed areas.

Benefits of additives application during combustion of phytomass

AIP Conference Proceedings, 2016
Phytomass, particularly wheat straw as a source of energy has countless benefits, but it has many problems in its direct burn too. The worst problem is the ash flow temperature. The aim of study was to analyze and reduce the problems of the wheat straw combustion. The experiment was conducted under realistic conditions.

Spatial distribution of phytomass carbon in Indian forests

Global Change Biology, 2002
AbstractA spatial analysis of phytomass carbon (C) in Indian forests for the period (1988–94) at the district‐level is reported. District‐level forest phytomass C (1988, 1994) was computed by combining remote sensing‐based forest area inventories on 1:250 000 scale, field inventories of growing stock volume by the Forest Survey of India (FSI), and ...

Phytomass (live biomass) and carbon of Siberian forests

Biomass and Bioenergy, 1998
Abstract The results of the phytomass (live biomass) estimates inventory for the Siberian forests are presented. These results are based on the following: (i) models estimating basic phytomass fractions for eight main forest-forming species (pine, spruce, fir, larch, Russian cedar, birch, aspen, oak); (ii) an ecoregional division of the territory ...
