Abstract

An experiment was carried out to study the effect of organic and inorganic substances on post harvest life of tuberose for two years from 2021 to 2023. The experiment was laid out in factorial randomized block design with three replications consisting eighteen treatments of organic and inorganic substances, viz., boric acid (2 % and 4 %), Salicylic acid (50 and 100 ppm), sodium benzoate (25 and 50 ppm), cow urine 20 %, Humic acid 5 %, GA3 (100 and 150 ppm), NAA (50 and 100 ppm), coconut water 20 %, FeSO4 (2 % and 4 %) and ZnSO4 (2 % and 4 %) and control. The results of pooled analysis of two years indicated that the spikes of tuberose treated with 4% boric acid and Salicylic acid 100 ppm significantly improved the post harvest life. Among post harvest parameters maximum flower diameter (4.60 cm) was recorded from boric acid 4 % whereas, application of Salicylic acid 100 ppm also recorded significantly minimum physiological weight loss (27.30 %), maximum membrane stability index (27.30 %). The maximum total soluble solids (17.97) and maximum florets opening (87.00 %) were also recorded in the same treatment. Quick dip of tuberose spikes in 4% boric acid and Salicylic acid 100 ppm were found beneficial for improving post harvest life of tuberose spikes.

Conclusion

From the present investigation, it can be concluded that quick dip (20 seconds) with boric acid @ 4% and Salicylic acid 100 ppm improved the postharvest life of tuberose flowers with maximum flower diameter, minimum physiological weight loss, maximum membrane stability index, maximum total soluble solids and maximum florets opening %.
