Recent Nitrogen Storage and Accumulation Rates in Mangrove Soils Exceed Historic Rates in the Urbanized San Juan Bay Estuary (Puerto Rico, United States)

Frontiers in Forests and Global Change, 2021
Tropical mangrove forests have been described as “coastal kidneys,” promoting sediment deposition and filtering contaminants, including excess nutrients. Coastal areas throughout the world are experiencing increased human activities, resulting in altered

Nitrogen accumulation and partitioning by winged bean in response to support systems [PDF]

, 1998
An experiment was carried out to determine the partitioning and accumulation of nitrogen in plant components, nitrogenase activity and their relationships with seed yield of a local cultivar of winged bean (Psophocarpus tetragonolobus (L.) DC.) grown on ...

Allometric Characteristics of Rice Seedlings under Different Transplanted Hills and Row Spacing: Impacts on Nitrogen Use Efficiency and Yield

Plants, 2022
The number of seedlings per hill and the configuration of plant row spacing are important management measures to improve rice yield. In the present study, we evaluated the impact of various seedlings per hill (1, 3, 6, and 9 seedlings hill−1) under four ...

Influence of Nitrogen Availability on Seed Nitrogen Accumulation in Pea

Crop Science, 1999
ABSTRACTThe final seed nitrogen concentration (the ratio of seed N and dry matter content) is highly variable in pea (Pisum sativum L.) and N remobilization during seed filling may limit yield by restricting the seed filling period. This study was conducted to determine how seed N accumulation is regulated in pea.

Nitrogen deficiency-induced molybdenum accumulation in wheat [PDF]

, 2022
In the present study, we conducted experiments using wheat to elucidate whether the increased accumulation of molybdenum in leaves under nitrogen deficiency is due to the plant’s own metabolic response, and further to estimate the role of molybdenum in ...

Effect of heavy metal stress in plant metabolism of solanaceous plant species with emphasis on nitrogen assimilation [PDF]

, 2011
Several plant species are able to accumulate and withstand large quantities of heavy metals in their tissues without dramatic alterations in their growth usually observed in plants. Such metal accumulating plants are tested and used for remediation of

Relationships of seed number with dry matter, nitrogen accumulation and the proportion of nitrogen distribution in inflorescence organs, nitrogen accumulation in non-inflorescence organs in Chinese milk vetch.

, 2023
Relationship between seed number and dry weight, nitrogen accumulation amount and nitrogen distribution rate in inflorescence organs of Chinese milk vetch (n = 180, A, B and D, respectively), and relationship between seed number and nitrogen accumulation

The Rate of Amino Acid Nitrogen and Total Nitrogen Accumulation in the Fetal Lamb

Experimental Biology and Medicine, 1981
AbstractTotal body water and nitrogen concentrations were determined for whole body homogenates of 18 fetal lambs. Nitrogen concentration averaged 10.5 ± 0.1 mg nitrogen/100 mg dry tissue. Amino acid represented approximately 82% of the total nitrogen and 55% of the total carbon content of the fetus.

Nitrogen Accumulation in Mycelium of Neurospora crassa [PDF]

Journal of General Microbiology, 1978
SUMMARY: Mycelium of Neurospora crassa accumulates arginine and glutamine when deprived of an amino acid or pyrimidines, or in the presence of cycloheximide or at the end of exponential growth. A large proportion of the accumulated arginine is sequestered in an osmotically sensitive compartment. Electron microscopy of this fraction shows it consists of
