Effect of Reducing Nitrogen Fertilization and Adding Organic Fertilizer on Net Photosynthetic Rate, Root Nodules and Yield in Peanut [PDF]
Plants, 2023 Long-term excessive application of chemical fertilizers can cause many problems, such as soil degradation and environmental pollution. Therefore, we reduced conventional nitrogen fertilization and added organic fertilizers in some cases to investigate ...

Machine learning models for net photosynthetic rate prediction using poplar leaf phenotype data. [PDF]
PLoS ONE, 2020 BACKGROUND:As an essential component in reducing anthropogenic CO2 emissions to the atmosphere, tree planting is the key to keeping carbon dioxide emissions under control. In 1992, the United Nations agreed to take action at the Earth Summit to stabilize

Effect of Altitude on the Response of Net Photosynthetic Rate to Carbon Dioxide Increase by Spring Wheat [PDF]
Plant Production Science, 2010 : The partial pressure of CO2 in air decreases with the increase in altitude. Therefore, increase in molar concentration of CO2 is smaller at higher altitudes than at lower altitudes for increases in molar fraction of CO2. This study aimed to predict the

Effects of Artificially Reproduced Fluctuations in Sunlight Spectral Distribution on the Net Photosynthetic Rate of Cucumber Leaves. [PDF]
Front Plant Sci, 2021 The effects of photosynthetic photon flux density (PPFD) fluctuations in sunlight have already been investigated; however, the spectral photon flux density distribution (SPD) has hardly been considered. Here, sunlight SPD fluctuations recorded for 200 min in October in Tokyo, Japan were artificially reproduced using an LED-artificial sunlight source ...

Trait variation across different life history stages of trees and its impact on net photosynthetic rate. [PDF]
Front Plant SciIntroduction Exploring the variation in plant functional traits from different perspectives not only helps to reveal how plants adapt to their environment but also reflects their ecological strategies. This study investigated the differences in trait variability across different life history stages and how these

Journal of the Japanese Society for Horticultural Science, 2005 On calm days throughout the growing season, much data on photosynthetic photon flux density at leaf surface (PPFD) and net photosynthetic rate (Pn) of individual ‘Napoleon’ cherry leaves were collected along with several meteorological elements. From these data, two multiple regression formulas were derived: one, to estimate PPFD using leaf and air ...

PHOTOSYNTHETIC AND RESPIRATORY COMPONENTS OF THE NET ASSIMILATION RATES OF SUGAR BEET AND BARLEY [PDF]
New Phytologist, 1965 SummaryThe net assimilation rate (E) of a plant population (the mean rate of increase in total dry weight per unit leaf area, measured over a period of 1 or 2 weeks), represents the excess of the rate of photosynthesis of the leaves (P) over the rate of respiration of the whole plants (R), both expressed per unit leaf area (E=P—R).

Diurnal Trends in Net Photosynthetic Rate and Carbohydrate Levels of Soybean Leaves [PDF]
Plant Physiology, 1973 A study was made of diurnal trends in net photosynthetic rate and carbohydrate levels of unifoliolate leaves of soybean (Glycine max L. Merrill) under constant environmental conditions (50,000-lux light intensity, 24.5 C air temperature, 60% relative humidity, and 300 microliters of CO(2) per liter of air).Net photosynthetic rate remained relatively ...
