Isoprene is most dominant volatile organic compounds (VOC) emitted by many plants. In this study 40 common Indian plant species were examined for isoprene emission using dynamic flow through enclosure chamber technique. Isoprene emission rates of plants species were found to vary from undetectable to 69.5 microg g(-1) h(-1) (Madhuca latifolia). Besides, an attempt has been made to evaluate suitability of 80 common Indian plant species for planting programmes. Out of 80 species, 29 species were moderate to high emitters (10 to < or =25 microg g(-1) h(-1)), 12 species were low emitter emitters (1 to < or =10 microg g(-1) h(-1)) and remaining 39 species were found to be negligible or non emitters (<1 microg g(-1) h(-1)) of isoprene. About 50% plant species selected for planting programmes in India were found to be moderate to high emitters of isoprene.
异戊二烯是许多植物排放的最主要挥发性有机化合物(VOC)。在本研究中,使用动态流通式封闭箱技术对40种常见的印度植物物种进行了异戊二烯排放检测。发现植物物种的异戊二烯排放率从无法检测到69.5微克克⁻¹小时⁻¹(阔叶破布木)不等。此外,还尝试评估80种常见印度植物物种对种植计划的适用性。在80个物种中,29个物种为中度至高排放者(10至<或=25微克克⁻¹小时⁻¹),12个物种为低排放者(1至<或=10微克克⁻¹小时⁻¹),其余39个物种被发现异戊二烯排放量可忽略不计或不排放(<1微克克⁻¹小时⁻¹)。在印度,约50%被选用于种植计划的植物物种被发现是异戊二烯的中度至高排放者。
