Magnetically treated irrigation water improved the adaptation of Spathoglottis plicata produced in vitro

In the search for other methods that contributed to the success of the micropropagation of plant species, the man has been able to establish relationships with phenomena that consider other sciences such as physics, and within this, the use of magnetism has been used as a promising tool in Plant Biotechnology. The objective of this study was to evaluate the effect of magnetically treated water (MTW) during the adaptation process of the orchid Spathoglottis plicata. To perform the magnetic treatment, a permanent magnets magnetizer with induction of 0.12 T in the irrigation water was used. The survival percentage, plant height, number of leaves, number of roots, leaf area and photosynthetic pigments content were evaluated. The magnetic treatment presented mean values higher than the control in all evaluated traits. With MTW the plants showed an improvement in the survival and the physiological traits associated to the greater photosynthetic pigments content. Magnetically treated water is efficient to improve and anticipate the adaptation of plants to ex vitro conditions.
