Materials and methods
Rubber, tea bags rrim 600 varieties planted around the age of 1 month to 16 liters pots using soil Chong. Of Field Crops Research Station Suwanvajukkasikij. Watering it every day and 16-16-16 fertilizer plant 2 times per month for about 1-2 months.In this experiment, a total of five series of experiments, the concentration of ozone gas (1) 200 ppb (2) 600 ppb (3) 900 ppb (4) 1,.200 ppb or (5) 1,.500 ppb compared to control all of the air without the increased concentration of ozone. Each treatment in both control and ozone treatment to provide air for 2 hours and 4 contain the rubber again.cooling pad box and blowing air through pvc pipe into 5-cubic-meter chamber for ozone treatment ozone will be replenished with ozone (oz-8010,.ozonic international, thailand) before the air enters the chamber. Then to measure the rate of net photosynthesis of leaves fully expanded rubber with a portable photosynthesis system (li-6400, li-cor, lincoln, nebraska,.usa) immediately after fumigation. Determined by the intensity of light 1.400 μmol ppfd m-2 s-1, relative humidity 50-80 percent, and the concentration of carbon dioxide (co2) in a total volume of 400 μmol mol-1 and a temperature of 27 - 35oc for treatment by ozone concentration 200 ppb.The light intensity levels from 0-2.000 μmol ppfd m-2 s-1, then the equation. non-rectangular hyperbola described the response to light and begin to calculate the slope of the light response curve (α) controls the curvature of the graph (θ),.Maximum photosynthetic rate (pmax) and respiration rate in the dark (rd) (johnson et al.1989) were used for the test, the average net rate of photosynthesis of rubber leaves the series was received with the usual air of ozone in each treatment was independent t-test

Device and method for
RRIM 600 varieties of tea bags, rubber age 1 month to 16 litres size pots planted with ground crops research station, Chong Kit Suwan cooperative cultivating the passive voice. Please feel free to get creative every day and provide fertilizer formula 16-16-16 a month twice a long cultivation of approximately 1-2 months. In this trial have all 5 sets of experiments, the concentration of ozone gas. As follows: (1) 200 ppb (2) 600 ppb (3) 900 ppb (4), 1,200 ppb or (5), 1,Every 500 ppb, compared with normal air set a control that does not have to increase the concentration of ozone. Each series of experiments in a control zone and provides treatment for a period of 2 hours and there they were 4 sa. Cooling pad box and blow air through the tube into the large Chamber PVC 5 cubic meters. For o-zone gas treatment with ozone, the ozone machines (OZ-8010, Ozonic air International Thailand), enters the Chamber to measure the rate of net photosynthesis of the timber that is expanding with a portable photosynthesis system (LI-6400, LI-COR, Lincoln, Nebraska, USA) immediately after the Cabinet passed the check light intensity value to 1,400 μmol PPFD m-2 s-1 Relative humidity 50-80 percent, and the concentration of carbon dioxide (CO2) in the air is equal to 400 μ mol mol-1 35oC and air temperature 27-for-treatment zones 200 ppb concentrations. At various levels, ranging from light intensity 0-2,0 μ mol PPFD m-2 s-1, and then use the equation for hyperbola non-rectangular explains how to respond to light and beam wonkha default slope of graph response to light (α) controls the curve of the graph (θ), Maximum photosynthesis rate (Pmax), and rate of breathing in the dark (Rd) (Johnson and Board, 1989) statistics used for a test average of net photosynthesis rate of timber between the normal air that has been specifically designed with ozone in each trial is independent t-test

Device and method
rubber plants, tea bags 600 RRIM aged about 1 months ago, the potted plant soil, using a 16 liter unit from the mouth of research stations, agricultural produce from Suwan. Kg, acts to parade every day, and my aunt, fertilizer formula 1-16-16 2 times a month is a long time to plant approximately 1 - 2 monthsIn the experiment with 5 sets of all the experiments, the concentration of ozone gas as follows: (1) 200 ppb (2), 600 ppb (3), 900 ppb (4), 1,200 ppb or (5), 1,All the 500 ppb compared to the control unit that is not a normal air is adjusted to increase the concentration of ozone control unit and each unit to try and ozone ตเม้นต์ tree, air time is 2 hours and a whirlpool dishwasher-safe rubber trees 4 spoolcooling pad box and blow air through the tube PVC shampoo into a number 5 cubic meters to take the trouble to get the Tree ozone ตเม้นต์ will be filled with gas ozone ozone production unit (OZ - 8010,Ozonic International, Thailand) before it will go into the air and then apply the shampoo fixed rate of net light synthetic rubber. The growth rate with the full portable photosynthesis system (LI - 6400, LI - COR, Lincoln, Nebraska,USA) immediately after passing through the hologram, the decree setting the intensity of the light 1,400 PPFDµmol M - 2 s - 1 relative humidity 50 - 80% and the concentration of carbon dioxide (CO 2). In the air as far as the 400µmol mol-1, and air temperature 27 - 35 oC to receive the Tree ตเม้นต์ ozone concentrations of 200 ppbAt the light intensity at different levels from 0-2,000 PPFDµmol M - 2 s - 1, and then use the equation non-rectangular hyperbola described the response to light and calculate it, the application of the graph starts to respond to the light (camera) controls the curvature of the graph (θ),The maximum light synthetic Rate (Pmax), and rates of Breathing in the dark (Rd) (Johnson and workgroups,1989.) The record is used to test the average rate of the net light synthetic rubber between the normal to the air is set in each unit that has been ozone experiment is independent T-test
