Growth indices and salinity tolerance threshold in a medicinal plant Andrographis paniculata Nees.

Salt tolerance threshold is a critical parameter for establishing plant salt tolerance, which is generally known as the relative yield response to increase root area salinity. In this study, we focused on relative growth rate (RGR) and salt tolerance index (STI) in Andrographis paniculata (AP). For this purpose, after 30 days from culturing, the seedlings were placed in different salinity levels (0, 4, 8,...

Repellency, fumigant and contact toxicities of essential oils of selected species from family Myrtaceae against Tribolium castaneum

The uncontrolled use of synthetic chemicals is a great hazard for the environment and consumers. Essential oils were introduced as less toxic agents against mammals and non-targeted insects. In the present study, essential oils from five plant species belonging to family Myrtaceae were extracted using hydro-distillation and their chemical composition was determined by gas chromatography mass spectroscopy. The essential...
