Effect of Silicon Amendment on Herbivore Induced Plant Volatiles of Rice Plant Infested by Brown Planthopper Nilaparvata Lugens (Stål)

Silicon (Si) is known to play a very important role in plant’s direct and indirect defense. In rice plants, its impact on induced volatiles released upon Brown planthopper (BPH), Nilaparvata lugens feeding less understood. The BPH-induced volatile compounds from Si amended plants were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). alteration Herbivore Induced Plant Volatiles (HIPV’s) blend was observed, wherein, total 38 HIPVs found be differentially released. HIPV mainly belongs alkane, alkene, alcohol terpene groups. Overall, amendment caused significant effect the composition of rice, some which are involved tri-trophic interaction.
