Led enhance the growth characteristics and affects the ex vitro aclimatization of sugarcane

The proper selection and optimization of light gas-permeable membranes in the culture flasks, can benefit plant quality improve ex vitro acclimatization capacity. objective was to compare morpho-physiological responses sugarcane plants different LEDs sealing flask types their impact acclimatization. Plants previously established were used inoculated flasks sealed with rigid caps or without gas-porous membranes, maintained growth room (25 ± 2 ºC, 16 h photoperiod, 72 μmol m-2s-1 irradiance from (white, blue/red, blue red). At 62 days cultivation physiological parameters evaluated. Blue/red provided a higher number shoots height. We observed greater leaves per clump blue/red LED, length largest root membranes. Red shoot fresh mass under white had mass, being same performance dry mass. highest content chlorophyll carotenoids kept red LEDs. percentage cultured (85%), (70%).For this, produce vitro, we suggest use whitout LED lamps, as they provide more hardening standing out excellent cultures.
