Carbon dioxide net assimilation exchange in a young pecan nut orchard during the growth cycle [PDF]

Global Journal of Environmental Science and Management, 2023
BACKGROUND AND OBJECTIVES: Pecan nut trees (Carya illinoensis K), due to their condition as woody and long-living species, in addition to the contribution of nuts for consumption, may also have an essential role in assimilating carbon dioxide and ...

Growth and morphological responses of Manna oak (Quercus brantii) seedlings to different light levels at nursery in the first growing year [PDF]

تحقیقات جنگل و صنوبر ایران, 2012
Manna oak (Quercus brantii) is the most important tree species in Zagross region of Iran that faces lack of natural regeneration by seed. Forest managers suggest reforestation by seeds or seedlings as the main silvicultural practice, in order to ...

Seasonal Variation of Net Assimilation Rate (NAR) of rice plants

Japanese Journal of Crop Science, 1968
For the purpose of obtaining some data serving as the basic ones for analyzing the relationship of rice growing seasons or areas to rice yields, authors tested the seasonal changes in NAR of rice plants, i. e., the seasonal changes in NAR in response to those in solar radiation and air temperature.

Seed Yield of Mungbean (Vigna radiata (L.) Wilczek) in relation to Growth and Developmental Aspects

The Scientific World Journal, 2012
Growth parameters such as leaf area (LA), total dry mass (TDM) production, crop growth rate (CGR), relative growth rate (RGR), and net assimilation rate (NAR) were compared in six varieties of mungbean under subtropical condition (24°8′ N 90°0′ E) to ...

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

Plants, 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 ...

CHANGES WITH AGE IN THE PHOTOSYNTHETIC AND RESPIRATORY COMPONENTS OF THE NET ASSIMILATION RATES OF SUGAR BEET AND WHEAT [PDF]

New Phytologist, 1966
SummaryThe net assimilation rates (E) of sugar beet and wheat growing in a controlled environment, and their components, the rates of photosynthesis (P) and respiration (R) of the whole plant per unit leaf area, were determined at intervals by a method described previously that depends on measuring the decrease in E when photosynthesis is prevented on ...

A provisional survey of the interaction between net photosynthetic rate, respiratory rate, and thallus water content in some New Zealand cryptogams [PDF]

, 1980
The effect of water content on photosynthetic and respiratory rates in eight lichen species and one bryophyte species were studied using an injection infrared gas analyser technique. All species snowed a strong relationship between net assimilation rate (
