“…Packaging of the Foxtail orchid spikes using polyethylene in treatment T5 created equilibrium of modified atmosphere (EMA) with high CO₂ and low O₂, resulting in less ethylene production. Our findings are also in line with Khongwir et al (2019), who reported higher MSI in polyethylene-wrapped flowers in Tuberose plants. Moreover, decreased ethylene production causes a reduction in membrane permeability and ultimately increases the membrane stability of foxtail orchid petals.…”

A postharvest experiment was conducted at the Department of Horticulture, AAU, Jorhat, to study the effect of different packaging technique(s) for the distant marketing of Foxtail orchid spikes. The seven treatments were as follows: T1: CFB box (control); T2: wrapping with 200 gauge polyethylene sheet + KMnO₄ sachet + CFB box; T3: wrapping with butter paper + KMnO₄ sachet + CFB box; T4: wrapping with Brown Paper + KMnO₄ sachet + CFB box; T₅: plastic vial containing 8-HQS (25 ppm) + wrapping with 200 gauge polyethylene sheet + CFB box; T6: plastic vial containing 8-HQS (25 ppm) + wrapping with butter paper + CFB box; and T7: plastic vial containing 8-HQS (25 ppm) + wrapping with Brown Paper + CFB box. Among these packaging treatments, T5 resulted in a significantly longer vase life (7.33 days after 3 days of storage under ambient conditions). Postharvest parameters such as the PLW (6.58%), TSS (10.08%), MSI (78.28%), and wilting of the first floret (3.41 days) were found to be greatest in T5. However, in terms of biochemical parameters, T5 was similar to T6 in terms of carbohydrate content (63.49 and 62.08 mg/100 ml, respectively), protein content (15.23 and 15.18%, respectively) and anthocyanin content (6.37 and 6.30 mg/L, respectively).

“…The minimum physiological loss in weight was noted in PE 400 gauge 0% ventilation under ambient condition which is mainly due to maintains humidity inside the packages which in turn slows down the process of moisture loss and proper balance of carbon di-oxide and oxygen concentrations which lower down the respiration. (Anzueto and Rizve 1985) [3] The results of this study are close agreement with the findings of Khongwir et al (2017) [8] in tuberose and Ravi et al (2004) [15] , Karuppaiah et al (2006) [7] in jasmine.…”

“…The maximum shelf life had recorded in polyethylene 400 gauge 0% ventilation might be reduce physiological loss in flowers resulting increased shelf life of flower which is mainly due to the moisture retentive nature of polyethylene packaging material prevents moisture loss and increase the relative humidity inside the packed flowers resulting rate of respiration and other enzymatic activity was probably much lower, there by delaying the senescence process in the petals. Similar findings reported by Madaiah and Reddy (1994) [9] , Khongwir et al (2017) [8] in tuberose loose flower, Nirmala and Reddy (1994) [16] in jasmine, Verma and Jhanji (2019) [14] in marigold under ambient condition.…”

The present investigation was done on effect of different packaging material on keeping quality of loose African marigold (Tagetes erecta L.) flower with objective to Study the Effect of Different Packaging Materials on Shelf life of Marigold loose flower during Winter Season. The research was arranged in Completely Randomized Design (CRD) with 11 treatments. Treatment consist different packaging material i.e. polyethylene 200 gauge (0, 1, 2% ventilation), polyethylene 400 gauge (0, 1 and 2% ventilation), gunny bags, onion mesh bag, card board box, crates and control (without packaging) and treatments replicated thrice. Among the treatments, The maximum values for parameters including freshness index, shelf life, relative water content, minimum physiological loss in weight and minimum spoilage percentage has been observed in T4 (polyethylene 400 gauge 0% ventilation) followed by T1 (polyethylene 200 gauge 0% ventilation). Card board box has found better than gunny bag, onion mesh bag and crates. Polyethylene 400 gauge 0% ventilation has been beneficial for increase shelf life of loose marigold flowers as compared to crates. Therefore, it may be concluded that as far as packaging material is concerned, polyethylene 400 gauge 0% ventilation has been found to be superior and may be recommended for transition of loose marigold flowers.

“…Similarly, in another investigation, Polypropylene 24μ was reported as best wrapping material for gerbera cut flowers (Patel et al 2016) whereas, Cellophane was found as best wrapping material for carnation (Sharma et al 2015) due to moisture retentive nature of cellophane that helps in maintaining turgidity. In the same way, study was conducted on tuberose and the higher freshness index of florets for all cultivars under study was recorded when florets were packed in 100 μ thick polyethylene bags with 0% ventilation (Khongwir et al 2019).…”

Floriculture is an in bloom industry comprises of cut flowers, loose flowers and cut greens. Flowers are climacteric which makes them defenseless for huge post-harvest losses. Senescence is a process that follows physiological maturity and leads to death of the whole plant, organ, tissue or a cell. It is one of the imperative factors determining the longevity of the flower. Post-harvest quality of flowers is affected by the pre-harvest factors, stage of harvest and also by postharvest factors. To have better post-harvest life, indulgence of crop-specific management practices is important.
