Assessment of Morpho-physiological Traits and Grain Yield of Corn (Zea mays L.) with Weed Interference [PDF]

open access: yesJournal of Agricultural Science and Sustainable Production, 2022
Background and Objective: In order to study of morpho-physiological attributes in corn under influence of weed, an experiment based on randomized complete block design with four replications was performed at the Moghan climate during 2020 growing season ...

Chemical data assimilation estimates of continental U.S. ozone and nitrogen budgets during the Intercontinental Chemical Transport Experiment-North America [PDF]

open access: yes, 2007
Global ozone analyses, based on assimilation of stratospheric profile and ozone column measurements, and NOy predictions from the Real-time Air Quality Modeling System (RAQMS) are used to estimate the ozone and NOy budget over the continental United ...

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

open access: yesGlobal 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 ...

Resource allocation, hyperphagia and compensatory growth [PDF]

open access: yes, 2004
Organisms often shown enhanced growth during recovery from starvation, and can even overtake continuously fed conspecifics (overcompensation). In an earlier paper (Ecology 84, 2777-2787), we studied the relative role played by hyperphagia and resource ...

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

open access: yesJapanese 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.

PHOTOSYNTHETIC AND RESPIRATORY COMPONENTS OF THE NET ASSIMILATION RATES OF SUGAR BEET AND BARLEY [PDF]

open access: yesNew 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).

Anti-transpirant effects on vine physiology, berry and wine composition of cv. Aglianico (Vitis vinifera L.) Grown in South Italy [PDF]

open access: yes, 2019
In viticulture, global warming requires reconsideration of current production models. At the base of this need there are some emerging phenomena: modification of phenological phases; acceleration of the maturation process of grapes, with significant ...

Increased Ratio of Electron Transport to Net Assimilation Rate Supports Elevated Isoprenoid Emission Rate in Eucalypts under Drought     [PDF]

open access: yesPlant Physiology, 2014
Abstract Plants undergoing heat and low-CO2 stresses emit large amounts of volatile isoprenoids compared with those in stress-free conditions. One hypothesis posits that the balance between reducing power availability and its use in carbon assimilation determines constitutive isoprenoid emission rates in plants and potentially even their
