Abstract:

An experiment was conducted to study the effect of food dyes in tinting of tuberose spikes at Floricultural Research Station, SKLTSHU, Rajendranagar, Hyderabad during 2015 -16 to 2017-18 for three years. The results of the experiment revealed that, food dye uptake quantity (ml) did not differ significantly due to food dyes and duration of dipping (Time) in dye solution. Similarly, number of florets open per spike and floret diameter (mm) was also not influenced by duration of dipping (Time) of flower spikes. However, maximum number of florets open per spike was recorded in Orange red 4 % (18.40) and minimum in control (17.01). Orange red 4 % and two hours of dipping registered maximum number of florets open per spike (19.45). Food dyes did not differ significantly for vase life of spikes, but one hour duration dipping recorded more vase life (4.48 days) and was on par with two hours dipping. The colour intensity differed due to different food dyes, the maximum intensity was observed in 8% concentration for two hours of dipping in all dyes. Among the different food dyes tuberose flower spikes dipped in kesar yellow, apple green and orange red at 8% had shown maximum intensity of colour in two hours of dipping time.
