“…They found that cut roses in hydrogen-rich water (HRW) had longer vase life, and dominant bacteria Pseudomonas fluorescens and Brevundimonas diminuta in (HRW) were related to vase life enhancement [ 16 ]. However, Robinson et al (2007) had the opposite results that adding Pseudomonas fluorescence did not prolong cut roses longevity; instead, increasing bacterial concentration decreased total water uptake and vase lives [ 35 ].…”

In cut flowers, xylem occlusion or blockage by bacteria negatively affects water balance and postharvest quality. Many studies have used culture-based methods to examine bacterial populations in vase water and their effects on flower longevity. It is still unclear if and how bacterial communities at the 16S rRNA gene (16S) level change during the vase period and how such change might correlate with postharvest longevity. This study compared the sequences of 16S amplicons from 4 different types of flowers and their vase water over the course of 7 days (Rosa spp., Gerbera jamesonii, and two Lilium varieties). The relative abundance of plant chloroplast and mitochondria 16S decreased significantly over the course 7 days in all 4 flowers as bacterial diversity increased. Richness and evenness of the bacterial communities increased over time, as did the number of rare taxa and phylogenetic diversity. Bacterial communities varied with time, as well as by flower source, types, and sample location (water, stem surface, whole stem). Some taxa, such as Enterobacteriacea and Bradyhizobiaceae decreased significantly over time while others such as Pseudomonas spp. increased. For example, Pseudomonas veronii, implicated in soft rot of calla lily, increased in both whole stem samples and water samples from Gerbera jamesonii. Erwinia spp., which includes plant pathogenic species, also increased in water samples. This work highlights the dynamic and complex nature of bacterial succession in the flower vase ecosystem. More work is needed to understand if and how bacterial community structure can be managed to improve cut flower vase life.

“…The decline in the increase in daily fresh weight of cut flowers can be the result of a rise in the number of bacteria in the vase solution (van Meeteren et al, 1999). An increase in the number of bacteria added to vase water has been shown to cause a reduction in water uptake (Robinson et al, 2007;Zagory & Reid, 1986). Microbial contamination and the metabolites from microbial organisms in vase water play a major role in vascular blockage, limiting postharvest life in many flower species, including Dendrobium (Brown et al, 1998;Loubaud & van Doorn, 2004;Maithong et al, 2018;van Doorn et al, 1989van Doorn et al, , 1991aYong & Ong, 1979).…”

Dendrobium, one of the largest genera of tropical orchids, is grown commercially on a large scale with an important economic impact in several ASEAN countries.Dendrobium orchids can be grown in a wide range of climates, but flower production is best under tropical conditions. Due to being the most popular orchid for cut flower production, many hybrids of Dendrobium have been produced with colorful and attractive blooms. Cut flowers of Dendrobium are popular worldwide. In addition, many Dendrobium cultivars can be grown as flowering potted plants and for other purposes such as in medicinal applications and for use in decorative products. Postharvest physiology and technology are important in maintaining the quality of both cut flowers and potted plants from production sites to the marketplace. Plants of the Dendrobium genus also contain a wide diversity of bioactive compounds that can be developed into medicinal and cosmetic products. This review describes the botany, cultivation, postharvest physiology, handling and utilization of Dendrobium.

“…In contrast to leaf water potential which varies greatly during a day depending on weather conditions and stomatal behaviour, the water potential of stems is more stable and tends to vary depending on the overall water status of plants. Among commercially available instruments for measuring stem water potential, the PSY1 Stem Psychrometer has been commonly used in the field and has proven to be accurate and reliable [37][38][39]. This device enables continuous measurement by attaching to the sapwood of the stem.…”

The measurement of sap movement in xylem sapwood tissue using heat pulse velocity sap flow instruments has been commonly used to estimate plant transpiration. In this study, sap flow sensors (SFM1) based on the heat ratio method (HRM) were used to assess the sap flow performance of three different tree species located in the eastern suburbs of Melbourne, Australia over a 12-month period. A soil moisture budget profile featuring potential evapotranspiration and precipitation was developed to indicate soil moisture balance while the soil-plant-atmosphere continuum was established at the study site using data obtained from different monitoring instruments. The comparison of sap flow volume for the three species clearly showed that the water demand of Corymbia maculata was the highest when compared to Melaleuca styphelioides and Lophostemon confertus and the daily sap flow volume on the north side of the tree on average was 63% greater than that of the south side. By analysing the optimal temperature and vapour pressure deficit (VPD) for transpiration for all sampled trees, it was concluded that the Melaleuca styphelioides could better cope with hotter and drier weather conditions.
