The salinity-adaptation physiology in different ecotypes of Phragmites communis in the Yellow River Delta Ⅱ.the characteristics of photosynthetic gas exchange in different ecotypes of Phragmites communis;

Photosynthetic gas exchange characteristics and carbonic anhydrase (CA) activity in flag leaves of high yield wheat variety Laizhou 953 as well as its filling grain course were studied with wheat variety Yangmai 5 as a control.

The leaf morphological characters and gas exchange at different leaf positions of 4 energy sugarcane genotypes were investigated at seedling and elongation stages by using CI-203 area meter instrument and CI-301PS photosynthesis system, respectively.

By covering different transparent membrane to filter UV-B radiation and using the method of ridge regression analysis,we studied the relationship between the photosynthetic gas exchange parameters of tobacco cultivar \'K326\' at its early maturity stage and the UV-B radiation intensity at the heights of 50 and 150 cm when the UV-B transmittances were 100%(CK),75%(A),50%(B) and 35%(C).

Combined impact of ozone and simulated acid rain on gas exchange,growth and yield of field-grown winter wheat;

An experimental study on the effect of different endotracheal suctions on the gas exchange in ARDS dog lung;

Effects of sustained inflation on hemodynamics and gas exchange in rabbits with acute respiratory distress syndrome;

Objective To study the relationship between respiration exchange ratio (RER) and tissue oxygen content in human skeletal muscle.
