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,

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 ...

Growth of marandu palisadegrass subjected to strategies of intermittent stocking Crescimento do capim-marandu submetido à estratégias de lotação intermitente [PDF]

open access: yesScientia Agricola, 2009
Grazing strategies alter sward leaf area patterns of growth, affecting herbage accumulation and utilisation. The objective of this experiment was to evaluate the growth of marandu palisadegrass (Brachiaria brizantha cv.

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 ...

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.

Optimization of leaf morphology in relation to leaf water status: A theory. [PDF]

open access: yes, 2020
The leaf economic traits such as leaf area, maximum carbon assimilation rate, and venation are all correlated and related to water availability. Furthermore, leaves are often broad and large in humid areas and narrower in arid/semiarid and hot and cold ...

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
