Results show that the daily change of photosynthetic rate in shining day is double peak curve, but in the first shining day after several raining days it is single peak curve.

Study on root activity,net photosynthetic rateand proteome of none-grafted and grafted cucumber(Cucumis satiuvs L.);

Changes laws of net photosynthetic rate of apple-pear;

Diurnal changes of net photosynthetic rate and transpiration rate of Reaumuria soongorica;

Mathematic models of cucumber net photosynthesis rate responding to CO2 concentration, temperature,and illumination intensity;

Effects of Leaf-cutting and Spikelet-thinning on Net Photosynthesis Rate of Rice During Grain Filling;

Relationship between leaf net photosynthesis rate of Lycium barbarum L. and it s environmental micrometeorological factors;

The growth stage changes of chlorophyll content,specific leaf weight and net photosynthetic rate of Panax ginseng leaves have been measured to study the correlations of these physiological characteristics with photosynthesis of Panax ginseng.

The results showed that, during water stress, the seedling growth was restrained seriously and photosynthesis decreases significantly, but with strengthening of water stress, the ability of osmotic adjustment of leaf was more improved.

With the Li-6400 system we measured the diurnal change of net photosynthesis,transpiration and water use efficiency of Calligonum arborescens in different seasons under treatments of drought and irrigation.
