Emission of Terpenoid Compounds from Rice Plants

The global cultivation area of rice is equivalent to 4% the world’s forest and may be an important sink source trace gases. To produce a precise terpenoid emission inventory, it essential obtain reliable data from plants. In present study, emissions various species were measured using flow-through chamber tower flux measurement methods. measurement, linalool was emitted above-ground parts three cultivars “Koshihikari”, “Nipponbare” “IR72”. rates gradually decreased (<0.1 µg gDW−1 h−1) within two days during periods. As touching stimulus might have enhanced emission, non-contact method, i.e., applied “Koshihikari” paddy. Linalool not detected, but α-pinene detected in atmosphere above (mean ± 95% confidence interval) 0.006 0.004 nmol m−2 s−1 on land-area basis. 1/200 previously reported monoterpene rate plants commercial chamber, largely different other reports. We provide paddy for first time, which more because method can avoid stimuli leaves stems. Although obtained very low, values contribute establishment BVOC inventory Asia.
