FitoMas-E: an alternative for in vitro rooting of sugarcane cultivars
Journal Title: Biotecnología Vegetal - Year 2016, Vol 16, Issue 4
Abstract
FitoMas-E increases and accelerates the germination of the seeds, stimulates the development of roots, stems, leaves and improves the nutrition of plants.The objective of this work was to evaluate the effect of FitoMas-E on the in vitro rooting of sugarcane cultivars ‘CP52-43’, ‘C87-51’ and ‘C1051-73’. A completely randomized experimental design was used with four treatments, three concentrations of FitoMas-E (0.5, 1.0 and 1.5 ml l -1 ) and indoleacetic acid (IAA) 1.3 mg l -1 as control in the liquid culture medium, with five repetition. At 15 days of culture the number of rooted shoots, height, leaves number and length of roots were evaluated. In the ex vitro acclimatization stage, its were quantified the number of plants with root, leaves and roots number per plant and it was measured the height after 45 days of transplanted. The results showed that the Fitomas-E in the cultivars ‘CP52-43’ and ‘C87-51’ achieved a number of shoots with a root similar to the control and in ‘C1051-73’ it exceeded it with the concentration of 0.5 ml l -1 of this biostimulant. Leaf height, leaves number and root length reached values significantly higher than control, with 1.0 ml l -1 phytostimulant, except for ‘CP52-43’ where similar root length was achieved among treatments. In the ex vitro acclimatization stage the in vitro plants rooted with the FitoMas-E achieved the required quality parameters, exceeding the controls for the variables height, number of roots and length of the longest root. Among genotypes there were significant differences for all cultivars.
