Influence of differences in leaf anatomy on net photosynthetic rates of some cultivars of Cassava

Photosynthesis Research, 1984
Gas exchange measurements and leaf anatomy of 10 cassava cultivars were conducted to study the interrelationship between the relatively high photosynthetic rates and the factors limiting internal CO2 diffusion. The internal mesophyll surface area per unit leaf surface area (A(mes)/A) and the intracellular components of CO2 diffusion and fixation ...

[Chlorophyll content and net photosynthetic rate of Machilus pauhoi and M. leptophylla].

Ying yong sheng tai xue bao = The journal of applied ecology, 2009
By using SPAD-502 chlorophyll meter, LI-6400 portable photosynthesis system, and spectrophotometer, the leaf SPAD value, net photosynthetic rate (Pn), and chlorophyll (a + b) content (Ct) of 3-year-old Machilus pauhoi and M. leptophylla seedlings were measured, and the relationships of SPAD value with Pn and Ct were analyzed. The M.

The simulation of three-dimensional canopy net photosynthetic rate of apple tree

Acta Ecologica Sinica, 2012
The distribution of photosynthesis within the canopy determines the productivity and quality in a fruit orchard.A model of photosynthesis was developed to simulate the three-dimensional(3-D) distribution of leaf net photosynthetic rate(Pn),stomatal conductance(Gs) and light use efficiency(LUE) in apple canopy.The experiment was conducted in a 'Fuji ...

Comparison of Net Photosynthetic Rate in Leaves of Soybean with Different Yield Levels

Journal of Northeast Agricultural University (English Edition), 2012
A total of nine soybean (Glycine max (L.) Merr.) cultivars were divided into three yield levels which were planted under the same environmental condition. The net photosynthetic rate was measured by LI-6400 portable photosynthesis system. The chlorophyll content and specific leaf weight were measured with regular methods.

Effects of elevated CO2 on net photosynthetic rate of trees in Changbai Mountain

Journal of Forestry Research, 1999
Net photosynthetic rates (NPRs) of four species seedlings,Pinus koraiensis, Pinus sylvestriformis, Fraxinus mandshurica andPhellodendron amurense, were measured at different CO2 concentrations and time respectively in Changbai Mountain during the growing season in 1999.

Modelling the net photosynthetic rate of Quercus mongolica stands affected by ambient ozone

Ecological Modelling, 1997
Abstract A mathematical model predicting the ambient O3 effect on the photosynthetic rate of Quercus mongolica stands was developed for the temperate deciduous forests in both the urban and the reference area in Korea. The diurnal pattern of hourly average O3 concentration monitored at the study site was simulated using the Gaussian equation.

Estimation of the net photosynthetic rate for waterlogged winter wheat based on digital image technology

Agronomy Journal, 2023
AbstractThe net photosynthetic rate (Pn) is one of the important indicators to measure photosynthetic capacity of crops. Therefore, it is critically important to find real‐time methods for accurately estimating Pn of winter wheat (Triticum aestivum L.). This information could provide guidance on the management of waterlogging stress.

Diurnal changes in net photosynthetic rate of Pueraria lobata and its impact factors

Forestry Studies in China, 2011
In order to identify the relationship between diurnal changes in the net photosynthetic rate (Pn) of Pueraria lobata and environmental factors, diurnal changes in the Pn of leaves of two P. lobata cultivars were measured using a CIRAS-1 portable photosynthesis measurement system (PP-Systems, UK).

Diurnal variation of net Photosynthetic rate in some Tropical Deciduous tree species

Indian Journal of Forestry, 2000
Diurnal leaf net photosynthetic rate was measured from 06.00 to 18.00 hours in summer and winter seasons in seven indigenous tropical deciduous tree species, viz., Chukrasia tabularis, Dolichandrone atrovirens, Eugenia jambolana, Gmelina arborea, Lannea coromandelica, Terminalia arjuna and Terminalia bellirica.

A simulation of global regimes of potential leaf net photosynthetic rates

Archives for Meteorology, Geophysics, and Bioclimatology Series B, 1982
Worldwide patterns of leaf net photosynthetic rates are produced by a parameterized model (PHOTO 1) in relation to plant climates. PHOTO 1 produces a continuum of photosynthetic plant leaf responses to climatic variables via its two submodels which characterize the phtosynthetic activity of generalized C4 and C3 plants.
