Agriculture, Melaleuca bracteata|

This experiment studied effects of salt stress on physiological indexes,contents and compositions of essential oil in Melaleuca bracteata to provide reference for the planting of M. bracteata in saline land.The cutting seedlings of M. bracteata were used as experimental materials to study the effects of different NaCl concentrations (0,100,200,300,400,500 mmol/L) on photosynthesis,proline content,malondialdehyde content,peroxidase activity,catalase activity,essential oil content and components of M. bracteata cuttings.The results showed that M. bracteata showed strong salt tolerance and oxidation resistance under salt stress.At 100,200 and 300 mmol/L NaCl treatment,the essential oil content of M. bracteata increased by 22.34%,22.14% and 57.83% compared with the control group (0 mmol/L),respectively.Therefore,appropriate salt stress has no effect on physiological indexes of M. bracteata,in addition could increase the content of essential oil in the leaves of M. bracteata.
