ResultsTemperature and relative humidity between control and ozone treatment is in the range 34-38 ° C and 51-64 percent, respectively, with no statistically significant difference. The experiments have been rubber ozone concentration of 200.Found that the rate of net photosynthesis (pn), where the stomata (stomatal conductance,.gs), transpiration rate, water (tr) and the characteristics of the leaves after the cabinet no different. For the response to light, the rate of photosynthesis between the control and ozone treatments to find a similar response.0-1000 μmol ppfd m-2 s-1, but when the light intensity higher than 1000 μmol ppfd m-2 s-1, the rate of photosynthesis to a constant value (figure 1) values ​​obtained from measuring light. response curve of the tree control and ozone treatments.(Α) with 0.041-.063 average value controls the curvature of the graph (θ) values ​​from 0.63 to 0.69, the average of the maximum rate of photosynthesis (pmax) were 11.6 - 18.1 μmol co2 m-2 s-1 and the average rate. Dark respiration (rd) is 0.15 - 0.44 μmol co2 m-2 s-1, with no significant difference statistically (table 1)

The trial results.
Temperature and relative humidity between control and treatment zones in the range of 34-38° c and 51-64 percent, according to La level. There are no differences in the statistical. From the experiment, they received gas ozone concentrations 200. I found that the rate of net photosynthesis (Pn), stomatal conductance (Pak na, Gs) ratio of bullish uncle (Tr) and the nature of the activity after there are no differences. For how to respond to light, with the rate of photosynthesis between control and treatment zone video showed similar responses. 0-1000 μ mol PPFD m-2 s-1, but when the light intensity higher than 1000 μ mol PPFD m-2 s-1. I found that the rate of synthesis of saengklap there is a constant (figure 1) from the light curve response evaluation of both control and treatment zone. (α) Has the value 0.041-NN0D063 the average of the control curve of the graph (θ). Has a value of 0.63-0.69 average of maximum photosynthesis rate (Pmax) has a value of μ mol m-2 CO2 11.6 18.1-s-1 and an average of the rate of respiration in the dark (Rd) has a value of 0.15-0.44 μmol CO2 m-2 s-1 That there are no differences in the statistical.

The trial
Temperature and humidity between the controls and the tree ozone ตเม้นต์ is in the range 34 - 38 degrees Celsius and 51 - 64 percent, according to the double-there is no difference in the statistics from the experiments on rubber. ozone gas concentration 200found that the rate of net light synthetic (Pn) at the mouth of the leaves (stomatal conductance,GS), discharge rate of my aunt (Tr) and the nature of the after the Minister has no different to get the response to the light on the rate of synthesis between the control and light ozone ตเม้นต์ tree found that there is a similar response.0 - 1000 PPFDµmol M - 2 S-1, but when the light intensity at higher than 1000 mol PPFD µm - 2 s - 1 found that the rate of return is Constant Light synthetic material (figure 1), the light of the assessment of both the control and response curve ozone ตเม้นต์ tree.(camera) has the value 0.041 - 0.063 average value of control the curvature of the graph (θ) has the value 0.63 - 0.69 average rate of the synthetic light up (Pmax) has the value 11.6 - 18.1 µmol CO 2 M - 2 s - 1, and the average rate of Breathing in the dark (Rd) has the value 0.15 - 0.44µmol CO 2M - 2 s - 1, there is no difference in the statistics (Table 1)
