Effect of Vase Solution on Value Addition and Vase-life of Tinted Tuberose (Polianthes tuberosa L.) cv. Prajwal

Abstract

Flower craft is one of the most flourish and dynamic enterprises in today's world. Tinting or artificial colouring of tuberose may be a potential value addition venture. Tuberose (Polianthes tuberosa L.) is a popular cut flower having white coloured fragrant blooms. Postharvest losses in many cut are estimated to be as high as 40% in the absence of floral preservatives. Blockage of vascular bundles due to microorganism proliferation is one of the reasons for cut flower postharvest losses. Therefore in this experiment effect of different biocides on kind and proliferation of microbes in vase solution of tinted tuberose were studied. In present experiment five different food dyes were used as tinting agent likes Blue, Apple green, Lemon yellow, Orange red and Rose pink at a concentration of 1%. Therefore an inspection was carried out to study the effect of different biocides (Calcium hypochlorite solution of 750 ppm, Sodium hypochlorite solution of 750 ppm, Benzyl adenine 450 ppm and Naphthalene acetic acid 250 ppm) on value addition and vase-life of tinted tuberose cv. Prajwal. In which flowers remained maximum fresh with higher vase-life in Lemon yellow followed by Rose pink and Apple green. Results suggest that among all chemicals Calcium hypochlorite (750 ppm) was best followed by Sodium hypochlorite (750 ppm), Benzyl adenine (450 ppm) and Naphthalene acetic acid (250 ppm).

Standardization of Vase Solutions for Maximum Buds Opening and Longer Vase-Life of Gladiolus Flower cv. Nova Lux

“…The higher concentration of sucrose found maximum vase-life that might be due to sucrose act as a carbon source, maintains mitochondrial structure (Halevy andMayak, 1981, Kaur et al, 2006) that might be the reason for longer vase-life of gladiolus spikes. The findings are in agreement with Kumar and Deen (2017) who reported flower spike was kept with 5% sucrose and 100 ppm aluminium sulphate provide 12 days vase-life of tuberose spike. These reports are in support of present findings.…”

“…Improvement of keeping quality and enhance the vase-life of cut flowers are important areas in Horticultural research. Sucrose and aluminium sulphate increased cut flower vase-life, by increasing water uptake and maximum florets opening of tuberose flower (Kumar and Deen, 2017).…”

“…The minimum (36.90%) drooping was observed on 10 th day of observation with 6% sucrose + 3% citric acid followed by 37.60% with 3% sucrose + 6% citric acid but there was no significant difference between these two treatments that might be because of higher per cent of sucrose into these treatments that provide necessary carbon and respiratory substrate to release energy required for florets opening. Kumar and Deen (2017) reported that tuberose spike was put in to 3% sucrose + 100 ppm aluminium sulphate, minimum drooping was recorded on termination of the experiment.…”

EVALUATION OF DIFFERENT PRESERVATIVE SOLUTIONS AND PACKAGING MATERIAL FOR IMPROVING POST HARVEST QUALITY OF GLADIOLUS (Gladiolus grandiflorus) CUT SPIKES

“…The preservative solution containing AgNO3 (250 ppm) + sucrose (3%) not only increase vase life but also helps in improving flower opening percentage, days to open basal floret, bloom spread, floret length, floret diameter, floral spike fresh and dry weight, and fresh weight loss. Similarly pulsing of cut flowers with sucrose and biocides combination increased floret opening in lisianthus (Kiamohammadi and Hashemaabadi, 2011), bird of paradise (Gendy and Hamad, 2011), orchid (Mattiuz et al, 2015), tuberose (Kumar and Deen, 2017) and gladiolus (Casares et al, 2017). Like floret opening percentage, Ahmed et al (2018) observed that biocide (Aluminium sulphate) and sucrose induce early opening of basal florets in Gladiolus hybridus.…”

Preservative solutions on vase life and quality of cut Polianthes tuberosa L.

“…The preservative solutions containing 3% and 4% sucrose showed higher uptake of vase solution, because sucrose helps to maintain water balance and delays turgor loss. Kumar and Deen (2017) state that a high concentration of sucrose solutions enhanced higher solution uptake in tuberose cv. Hyderabad Double.…”
