... It aims to enhance mental and physical well-being through structured plant-related activities [5,6]. Positive effects across various dimensions physical, psychological, cognitive, social, behavioral, and educational have been documented, with participants in therapeutic agriculture commonly experiencing physical benefits, such as improved health and agricultural skills, as well as psychological gains, including increased self-esteem, emotional stability, quality of life, and trust in others [7][8][9]. Furthermore, gardening activities allow individuals to engage with natural elements even within urban settings, facilitating interactions with nature despite environmental constraints [10]. ...

... Yang et al. (2021) suggested using fungicide in farm storage after harvest because treatment of 1% chrysal professional, RVB 0.1% and Floralife quick dip and Floralife Clear extended the vase life in farm storage, transport, and under preservative solution. Antimicrobial biocides such as sodium hypochlorite (NaOCl), sodium dichloroisocyanuric acid (DICA), 8-hydroxyquinoline citrate (8-HQC), 8-HQS, Physan 20 TM , benzalkonium chloride (C 17 H 30 CIN), aluminum sulfate (Al 2 (SO 4 ) 3 ), silver nitrate (AgNO 3 ), and silver thiosulfate (STS) extended the vase life by reducing bacteria in the vase solution for cut flowers (Macnish et al., 2008;Lee and Kim, 2019). However, it was toxic to flowers or caused environmental pollution at their disposal (Xie et al., 2008). ...

... Floral shape, color, and scent serve as visual and chemical signals, playing crucial roles in attracting pollinators and ensuring the reproductive and evolutionary success of plants. Additionally, these factors are significant aesthetic features that contribute to the demand for products in the floriculture industry (Ainsworth, 2006;Yeon and Kim, 2020). In Iran, narcissus plants are among the most popular flowers because of their distinctive shape, vibrant color, and delightful fragrance. ...

... A similar conclusion was made by Zhang et al. (2023) for the aroma variation of plum fruits. Modules related to phenylpropanoid biosynthesis (Savoi et al., 2016) and terpenoid synthesis (Anwar et al., 2021) are particularly noteworthy, as they are known to contribute to pigmentation and aroma (Yeon & Kim, 2021). ...

... Most modern roses have double flowers with two or more layers of petals, several of which express a mid-form between the petals and stamens, called petaloid stamens or stamenoid petals [5]. This morphological transition between petals and stamens, a reversal phenomenon, is a phyllody symptom characterized by leaf-like structures replacing normal floral organs [6,7]. ...

... Lee et al. (2021) showed that supplemental lighting with sulphur plasma lamps (PLS) or HPS with a PPFD of 120 μmol·m −2 ·s −1 for 14 h improved almost all of the characteristics of cut roses 'Aqua' and 'Brut' compared with the control. The results of Shi et al. (2021) illustrated that supplemental lighting helps extend the vase life of cut roses. However, the negative effect or lack of effect of supplemental lighting on the vase life of cut rose flowers has also been reported (Bredmose, 1998;Mortensen & Fjeld, 1998). ...

... As a highdemand crop in the floriculture industry, roses are extensively propagated to meet market needs. Stem cutting is a widely used propagation method as it preserves the superior hindered by suboptimal environmental conditions, including fluctuations in humidity and temperature (Braun & Wyse, 2019;Shin et al., 2023;). To address these issues, protective cloches, or plant covers, are used to create a controlled microenvironment, enhancing rooting and growth dynamics. ...

... Over the last two centuries, many breeders have contributed to the development of new rose varieties with morphological diversity in petal number, color, fragrance, floral shape and structure, flowering time, and frequency [2,3]. In flower forms, standard-type roses produce a bigger flower on a stem compared with spray-type ones having more than four to five flowers per shoot [4]. Consequently, modern rose plants (Rosa hybrida L.) have become representative cut flowers with diverse phenotypes [4]. ...
