Orthotropic tension behaviors of poplar and Chinese fir were investigated at a wide relative humidity (RH) range. Background and Objectives: Poplar and Chinese fir are typical plantation tree species ...
The effect of ambient humidity on the photosynthetic rate of a rice plant population model (area: 120×60 cm, Planting density: about 40 plants/dm2, leaf area index: 6∼7, plant height: about 30 c...
The effect of relative humidity (RH) on the growth and dry matter production of rice seedlings was investigated at the early vegetative stage. Plants were grown for 10 days under 60 or 90% RH at 12-hr...
The effect of relative humidity (RH) on the dry matter production and nitrogen absorption of rice seedlings (age in leaf mumber of 5) was investigated. Plants were grown for 4 days under 60 or 90% RH ...
Rice seedlings were grown on a medium containing polyethylene glycol (PEG), which lowers the osmotic potential of the medium under high humidity, or on a medium containing no PEG under a low humidity,...
^<13>C-labelled CO2 was fed to rice seedlings for 60 min in the light under low (60%) or high (90%) humidity. The amount of 13C assimilated by the leaves under high humidity was much greater than that...
Rice seedlings(age in leaf number of 3)were grown for 10 days at 75% relative humidity in the light period(12-hr)and at 60, 75, or 90% humidity in the dark period(12-hr)Dry matter production of the pl...
Pulse treatment with sucrose extends the vase life of cut Eustoma flowers, but leaf injury is sometimes observed following this treatment. To investigate the factors causing leaf injury, cutMira Cor...
The objective of this study was to determine the influence of relative humidity and dipping in water on the static and dynamic coefficients of friction of apple on four surface types. Knowledge of the...

Better growing conditions are achieved in greenhouses by maintaining a higher internal ambient as compared with external ambient temperature. A computer-based control and monitoring system which provi...
Spatial distribution the ambient temperature, relative humidity and air velocity were determined for different storage temperatures such as 0 oC, 1 oC, 2 oC and 3 oC in an experimental cold store. Map...
