[Abstract]

Rice plants of different verity were hydrogenically cultivated for testing the methane transportation potential. The growth of rice was followed during the whole vegetation season. The seedling period of all the tested plants were around 30 days. Tillering stage occurred around 70 days. Parameters to describe the plant physiological properties were monitored. Methane emission rate from rice cultivars ranged between 0.6-1.9 umol/min/plant. Difference of methane transportation potential caused by rice verities were found. Methane emission rate is found to be correlated with plant properties, internal volume of stems. Under the present testing condition, photosynthesis was more intensive than plant respiration.
