Net Assimilation Rate Determines the Growth Rates of 14 Species of Subtropical Forest Trees. [PDF]

open access: yesPLoS ONE, 2016
Growth rates are of fundamental importance for plants, as individual size affects myriad ecological processes. We determined the factors that generate variation in RGR among 14 species of trees and shrubs that are abundant in subtropical Chinese forests.

Net Assimilation Rate and Agronomic Efficiency of Nitrogen in Tartago (Ricinus communis L.) (Euphorbiaceae) in Dry Climate [PDF]

open access: yesScientifica, 2020
To know the dynamics of net assimilation rate and the agronomic efficiency of nitrogen in the Tartago crop, seeds of three accessions were collected in Teotitlán de Flores Magón, Oaxaca, Mexico. The treatments consisted of nitrogen fertilization of 0, 20,

Elevated Carbon Dioxide and Chronic Warming Together Decrease Nitrogen Uptake Rate, Net Translocation, and Assimilation in Tomato [PDF]

open access: yesPlants, 2021
The response of plant N relations to the combination of elevated CO2 (eCO2) and warming are poorly understood. To study this, tomato (Solanum lycopersicum) plants were grown at 400 or 700 ppm CO2 and 33/28 or 38/33 °C (day/night), and their soil was ...

Growth Dynamic of Sugarcane Cultivars C97-366 and C99-374 for Forage Production

open access: yesAgrisost, 2021
Context: Plant growth analysis is a valuable tool to detect biomass formation and accumulation. The determination of growth indexes enables plants to adapt to different edaphoclimatic conditions, and to select the most promising responses among them ...

A Method of Calculating Net Assimilation Rate [PDF]

open access: yesNature, 1963
A USEFUL measure of the photosynthetic efficiency of plants is ‘net assimilation rate’ (E) defined by Gregory1 as the rate of increase of dry weight (W) per unit of leaf area (L); that is: In measuring W the plant is destroyed, so changes in W can be determined only by successive ...

Papaya (Carica papaya L.) Leaf Area Estimation and Single-leaf Net Photosynthetic CO2 Assimilation Rate Following Leaf Defoliation and Fruit Thinning

open access: yesHortScience, 2020
Papaya (Carica papaya L.) leaves are large, up to 70 cm wide, and frequently deeply lobed, with seven to 13 major veins. The scan width of current handheld digital leaf area instruments is generally less than 15 cm.

Leaf and Community Photosynthetic Carbon Assimilation of Alpine Plants Under in-situ Warming

open access: yesFrontiers in Plant Science, 2021
The Tibetan Plateau is highly sensitive to elevated temperatures and has experienced significant climate warming in the last decades. While climate warming is known to greatly impact alpine ecosystems, the gas exchange responses at the leaf and community

Evaluating sago palm (Metroxylon sagu Rottb.) photosynthetic performance in waterlogged conditions: utilizing pulse-amplitude-modulated (PAM) fluorometry as a waterlogging stress indicator

open access: yesJournal of the Saudi Society of Agricultural Sciences, 2020
Photosynthetic performance of sago palm (Metroxylon sagu Rottb.) was evaluated in normal and waterlogged conditions. Net assimilation rate (AN), light response curve of net assimilation rate (AN/I) and pulse-amplitude modulation fluorescence vs ...

Intrinsic Fluctuations in Transpiration Induce Photorespiration to Oxidize P700 in Photosystem I

open access: yesPlants, 2020
Upon exposure to environmental stress, the primary electron donor in photosystem I (PSI), P700, is oxidized to suppress the production of reactive oxygen species that could oxidatively inactivate the function of PSI.
