Essential oil composition of sweet basil (Ocimum basilicum L.) in symbiotic relationship with Piriformospora indica and paclobutrazol application under salt stress.

Essential oil content and oil composition of paclobutrazol treated sweet basil (Ocimum basilicum L.) plant inoculated with Piriformospora indica under salt stress were investigated by GC-MS. The results show a slight increase in essential oil content when basil plants subjected to moderate salinity stress (3 dS m of NaCl).
