Influence of magnetic field on the growth, development and rhizome yield of turmeric (Curcuma longa L.)

Static magnetic field (SMF) as a priming method (magnetopriming) is used to invigorate plant growth and development culminating in improved productivity. In vitro shoot buds of Curcuma longa were exposed to a static magnetic field of 200 mT intensity for different periods, from 20 to 120 min. Variou...

Description
Summary:Static magnetic field (SMF) as a priming method (magnetopriming) is used to invigorate plant growth and development culminating in improved productivity. In vitro shoot buds of Curcuma longa were exposed to a static magnetic field of 200 mT intensity for different periods, from 20 to 120 min. Various growth parameters such as fresh weight, shoot length, leaf area as well as field performance of the plants in terms of rhizome yield were assessed to study the effects of SMF. The results showed that the SMF for shorter duration (40 min exposure time) stimulated shoot development with maximum increase in the fresh weight and shoot length whereas increase in exposure time led to a reduction in shoot length and biomass. Field data on plants exposed for 40 min showed better biomass and maximum improvement in rhizome yield than control plants. The results suggest that the 200 mT SMF has a stimulatory effect on the growth of in vitro grown C. longa shoots as well as on rhizome yield under field conditions. Key message Static magnetic field of 200 mT for an exposure time of 40 min. resulted in better growth and development of in vitro turmeric plants, and improved rhizome yield under field conditions.
