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 ...

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 ...

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 ...

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.

The CarbonTracker Data Assimilation Shell (CTDAS) v1.0: implementation and global carbon balance 2001–2015 [PDF]

Geoscientific Model Development, 2017
Data assimilation systems are used increasingly to constrain the budgets of reactive and long-lived gases measured in the atmosphere. Each trace gas has its own lifetime, dominant sources and sinks, and observational network (from flask sampling and ...

Influence of Soil Amendment on the Relative Growth Rate and Net Assimilation Rate of Phaseolus vulgaris and Vigna aconitifolia

Journal of Applied Life Sciences International, 2020
Background: Soil pH is one of the most important factors that contribute to crop growth and productivity. The present research was designed to assess the influence of soil amendment using organic manure and agricultural lime on the relative growth rate (RGR) and net assimilation rate (NAR) of Phaseolus vulgaris and Vigna aconitifolia grown on soils ...
