Summary: This study investigates the postharvest performance and physiology of Mokara orchid cut flowers, specifically focusing on the effects of ethylene on flower senescence and vase life longevity. The results demonstrate that ethylene plays a significant role in regulating the senescence of Mokara flowers, and the use of ethylene inhibitors can effectively improve their vase life duration. This research provides valuable insights for developing postharvest treatments for Mokara hybrids.

Summary: This study compared the changes in 16S amplicons from different types of flowers and their vase water over time, and found that the relative abundance of plant chloroplast and mitochondria 16S decreased while bacterial diversity increased. The richness and evenness of bacterial communities also increased over time.

Summary: It is important to clarify the senescence mechanism of cut rhododendron flowers to prolong their vase life. Transcriptome sequencing was used to investigate flower senescence in Rhododendron 'Hong Shanhu.' The results indicated that the senescence of cut rhododendron flowers may be related to water stress rather than ethylene.

Summary: The gene expression and aging process of inner and outer florets in composite flowers of dahlia are different, and the gene expression of young florets differs from that of aging florets in the whole flower head. In some species, the plant growth regulator ethylene is involved in floral senescence, but there is a lack of conclusive data regarding its importance in dahlia.

Summary: The study shows that pretreatment with lysosomal enzymes can extend the vase life and retain the ornamental value of cut flowers, affecting factors such as stomata, microbial population, and soluble carbohydrate contents. This has significant importance in improving marketability of cut flowers in the flower industry, making lysosomal enzymes a potential eco-friendly and effective material for pretreatment agents.

Summary: This study found that soaking and spraying 6-BA can significantly extend the vase life of Curcuma alismatifolia cut flowers, particularly the variety 'Siam Shadow'. Physiological, biochemical, and transcriptomic analyses revealed the involvement of antioxidant enzymes, jasmonic acid, and senescence-associated transcription factors in delaying bract senescence. The findings suggest that 6-BA can act as a potential preservative by affecting gene expression related to JA biosynthesis and signal transduction, antioxidant enzymes, and senescence-associated transcription factors.

Summary: The study investigated the effects of active and passive modified atmosphere packaging on the biochemical properties of cut Dendrobium Sonia orchid flowers. Results showed that different types of plastic films could prolong the storage life of orchid flowers, while MAP efficiently reduced respiration rate, ethylene production, anthocyanin degradation, protein degradation, and electrolyte leakage. In addition to extending storage life, the research provided insights on the biochemical properties of orchid flowers stored in MAP environment.

Summary: Brassinosteroids can affect ethylene production and physiology of lisianthus cut flowers, and the effects are highly dose dependent. Low concentrations of EBL significantly improve the vase life of lisianthus cut flowers, while high concentrations may have negative impacts.

Summary: This study investigated the effect of a composite of multi-walled carbon nanotubes (MWCNTs) and polyvinyl pyrrolidone (PVP) on the longevity of cut Alstroemeria flowers. The results showed that adding 3 mg L-1 MWCNTs/PVP significantly extended the vase life of cut Alstroemeria flowers and reduced leaf yellowing symptoms.

Summary: This study compared the quality of cut Phalaenopsis V3 flowers from Korea and China across different seasons, finding that Chinese flowers had longer vase life, larger flower diameter, and lower ethylene production. Additionally, Korean flowers showed poorer performance in water uptake, fresh weight, and flower diameter.

Summary: The study found that endogenous PSK alpha signaling affects the physiological activities of rose petals during flower opening by regulating PSKR1 and cGMP accumulation, delaying senescence. On the other hand, during flower senescence, PDE expression inhibits cGMP signaling, accelerating petal aging.
