“…Data revealed that microwave oven drying with silica gel as a drying media noted maximum percent of moisture loss (77.13%) recorded in Jatropha (T 3 ). Similar results were observed by Acharrya et al [4], Hemant et al [5], Malakar et al [6], Kumari et al [7] and Jagadeeswari et al [8].…”

Fresh flowers and foliages are delightful and visually striking, it can be arduous to sustain their charm and pristine appearance over an extended duration, However this obstacle can be overcome by drying the flowers and foliages, enabling them to retain their allure. The present investigation the effect of different drying techniques of flowers and foliages and its value addition was carried out at the post harvest laboratory of Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (UP) during 2022-23. The experiment was laid out in Completely Randomized Design comprising of two different methods of flower drying i.e. microwave oven drying with silica gel and microwave oven drying with sand and replicated three times containing six flowers per replication for six different flowers and foliage i.e. Rose, Gerbera, Jatropha, Dracaena, Fern and Thuja. The aim of this investigation was to evaluate the drying techniques of Rose, Gerbera, Jatropha, Thuja, Fern and Dracaena. Maximum moisture loss was obtained in (T3) Jatropha embedded in silica gel and dried in microwave oven (77.13%). Best score in sensory evaluation in terms of colour, shape and texture was found highest in (T5) Dracaena embedded in silica gel and dried in microwave oven (scores- 4.18, 4.38, 4.03). So, the best drying technique considered was microwave oven drying with silica gel as an embedding medium.

“…According to Broschat and Donselman, 1983a;Broschat and Donselman, 1983b) Heliconia can thrive best under the semi-shaded condition while excessive shade and crowding can cause the reduced yield with weak, lanky stems as most evident in H. psittacorum groups. Malakar et al (2016) had also corroborated the same based on the outcomes of their experiment on evaluation of agro-morphological attributes of diversified Heliconia genotypes under West Bengal, India, condition but any standardized range of shade percentage yet to be made. The other tropical cut flowers also prefer semi-shaded condition like in Alpinia 30% (Criley, 1988), Curcuma 50-70% (Criley, 2014), Anthurium 30%-75% (Kamemoto, 1962) while according to Ismail et al (2019), Etlingera needs partial shade (standardized percentage not found) but the empirical views of the authors of this review are paradoxical to the view of these researchers.…”

“…Taking into consideration the great potential and burgeoning demand as a cut flower, our review will focus on Heliconia(>250 inter and intra-specific varieties are existing), commonly known as 'False Bird-of-Paradise', which belongs to the family Heliconiaceae (Abalo and Morales, 1982;Kress, 1990;Berry and Kress, 1991;Criley and Broschat, 1992;Abadie and Berreta, 2001;Urooj-UI-Nissa et al, 2015;Malakar et al, 2016;Avendaño-Arrazate et al, 2017;Krause et al, 2023). This review will specifically focus on the pre-and post-harvest factors that affect the desired attributes of heliconia cut flowers as expected by consumers.…”

Aesthetic attributes and easy-to-grow nature of tropical cut flowers (TCFs) have contributedto their potential for increased production. The dearth of information regarding agronomic practices and lack of planting materials are the key hindrances against their fast expansion. Unconventional high-temperature storage requirements and the anatomy of the peduncle contribute topoor vase life performance, while troublesome packaging and transport due to unusual size and structureprimarily cause post-harvest quality deterioration. Nonetheless, the exotic floral structuresconsequently increase market demand, particularly in temperate countries. This boosts studies aimed at overcoming post-harvest hindrances. While a few TCFs (Anthurium, Strelitzia, Alpinia, and a few orchids) are under the spotlight, many others remain behind the veil. Heliconia, an emerging specialty TCF (False Bird-of-Paradise, family Heliconiaceae), is one of them. The structural uniquenessand dazzling hues of Heliconia genotypes facilitate shifting its position from the back to the forefrontof the world floriculture trade. The unsatisfactory state-of-the-art of Heliconia research and the absence of any review exclusively on it are the key impetus for structuring this review. In addition to the aforementioned setbacks, impaired water uptake capacity after harvest, high chilling sensitivity, and the proneness of xylem ducts to microbial occlusion may be counted as a few additional factors that hinder its commercialization. This review demonstrates the state-of-the-art of post-harvest research while also conceptualizing the implementation of advanced biotechnological aid to alleviate the challenges, primarily focusing on Heliconia (the model crop here) along with some relevant literature on its other allied members. Standard harvesting indices, grading, and packaging are also part of the entire post-harvest operational chain, but since these phases are barely considered in Heliconia and the majority of tropical ornamentals except a few, a comprehensive account of these aspects has also been given. The hypothesized cues to nip chilling injury, resorting to different bio-chemical treatments, nano-based technology, and advanced packaging techniques, may help overcome preservation difficulties and propel its transition from niche to the commercial flower market. In a nutshell, readers will gain a comprehensive overview of how optimum post-harvest handling practices can rewardingly characterize this unique group of TCFs as the most remunerative component.

“…Similarly, in the immersion method of glycerine application (M 2 ), maximum volume uptake (19.99 ml) was seen in cut foliage treated in distilled water and minimum volume uptake (1.12 ml) was observed in cut foliage treated with 100% glycerine. Data showed that treatment with higher concentration of glycerine significantly reduced volume uptake owing to its viscosity and glycerine uptake was increased with the increase of extended absorption duration (Malakar et al 2016). Also, measurable respiration with metabolic functions ceased within 1.5 days of commencing treatment (Campbell et al 2000).…”

An investigation was done in the Department of Horticulture, School of Agricultural Sciences and Rural Development, Medziphema, Nagaland University during 2021 to study the effect of glycerine on drying of common lady fern (Athyrium filix-femina). Results showed that immersion method (M2) of glycerine application recorded the maximum score for the texture (3.71), shape retention (3.88), brittleness (3.82) and overall acceptability (4.06) when compared to uptake method (M1) of glycerine application. Among the glycerine concentration, 25% glycerine scored maximum (4.41) for overall acceptability followed by 50% glycerine (4.34) and minimum score (3.39) was recorded in control (distilled water). From the findings, it may be concluded that the immersion method (M2) of glycerine application was better when compared to uptake method (M1) in terms of all qualitative and quantitative characters and 25% glycerine was the best among the different glycerine concentration for drying of cut foliage of common lady fern.
