treegrowth CO2fertilization tree-ring dendrochronology InTECmodel
2024/3/12
Although CO2 fertilization on plant growth has been repeatedly modeled to be the main reason for the current changes in the terrestrial carbon sink at the global scale, there have been controversial f...
Stanford study shows U.S. grasslands affected more by atmospheric dryness than precipitation
Stanford U.S. grasslands atmospheric dryness precipitation
2017/3/30
A new study showing dryness of the atmosphere affects U.S. grassland productivity more than rainfall could have important implications for predicting how plants will respond to warming climate conditi...
Atmospheric deposition of nitrogen and sulphur in relation to critical loads of nitrogen and acidity in the Czech Republic
acidity atmospheric deposition
2015/3/3
Estimates of dry and wet deposition of sulphur and nitrogen were compared with critical loads of sulphur
and nitrogen in the Czech Republic on 1 ×1 km grid. Deposition was estimated from monitored a...
Isotope ratios and concentration of N in needles, roots and soils of Norway spruce (Picea abies [L.] Karst.) stands as influenced by atmospheric deposition of N
N-deposition 15N nitrogen spruce soil
2015/2/6
This study aims to investigate the changes in isotope ratios in foliage and soils of two Norway spruce (Picea abies [L.] Karst.) forests greatly differing in their atmospheric N deposition and climati...
Introduction of a new atmospheric pressure plasma device and application on tomato seeds
Atmospheric Pressure Plasma Treat Voltage Tomato Seed Yield
2013/3/4
We designed new atmospheric pressure plasma device, to explore appropriate voltage of plasma treatment that promote traits and yield of to-mato, tomato seeds were treated by plasma at 4760 to 6800 V, ...
Effects of Atmospheric Partial Pressure of Carbon Dioxide and Phosphorus Nutrition on the Ultrastructure of Rice (Oryza sativa L.) Chloroplasts
Carbon dioxide Chloroplast Mesophyll cell Rice Phosphorus Starch accumulation
2009/7/29
Rice plants were grown in artificially illuminated growth cabinets under combinations of atmospheric partial pressure of CO2 (35 vs. 70 Pa) and phosphorus (P) nutrition (3 vs. 300 μM) to examine their...
Effects of Elevated Atmospheric Carbon Dioxide Concentration on Silica Deposition in Rice (Oryza sativa L.) Panicle
Elevated [CO2] Oryza sativa L. Panicle SEM Silica Transpiration X-ray microanalysis
2009/7/23
The effects of elevated carbon dioxide concentration ([CO2]) on silica deposition on husk epidermis of rice (Oryza sativa L. cv. Akitakomachi) during the flowering stage were investigated in this stud...
Differences in the Morphophysiological Response to Atmospheric Humidity between Paddy and Upland Rice
Stomatal density Transpiration Paddy rice Atmospheric humidity
2009/7/9
The effects of atmospheric humidity on vegetative growth of paddy and upland rice were compared. A low atmospheric humidity (60%RH) significantly decreased the dry-matter production in paddy rice but...
