High temperatures and the duration of extreme heat waves are expected to be more frequent in the next decades. Therefore, understanding and determining the high temperature that causes irreversible damage in Dahlia flowers is of high interest for preparing farmers to mitigate and adapt their crop to climate change. The objective of this study was to determine the upper lethal temperature that causes irreversible damage on buds and flowers on open field grown dahlia. Commercial open field dahlia crops in five locations in Rio Grande do Sul (RS) State, Southern Brazil, during two growing seasons (2021/22 and 2022/23) were used in this study. During the period from 20 December 2021 to 30 January 2022 and from 14 January 2023 to 20 January 2023, daily observations were made in the dahlias in the five locations in order to identify symptoms of heat stress on leaves, buds and flowers such as leaf rolling, wilting, dry leaf edges, sunscald, burning and rotting. The appearance of those symptoms was correlated with maximum daily air temperature in order to estimate the lethal temperature. Irreversible heat injury in buds and flowers of open field grown dahlia start when air temperature reaches 35 oC. Artificial shading, irrigation and planting date are management practices that can help farmers to protect dahlia flowers from heat stress.","PeriodicalId":19699,"journal":{"name":"Ornamental Horticulture","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67337188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus of research is to extend the shelf life of cut flowers to maintain quality and customer satisfaction. Techniques such as storage at low temperatures, use of preservative solutions, and new technologies such as nanotechnology can help maintain the quality of the floral stem. The present review aims to analyze various techniques used to extend the post-harvest shelf life of floral stems. For this purpose, a systematic search was conducted on major indexing platforms for studies published in 2023, which were subjected to a meta-analysis. The global effect size and moderator effects were calculated to assist in decision-making for future studies in floriculture. The results indicated that the addition of preservatives to solutions, variations in storage temperature, and the use of electromagnetic fields were the most effective techniques in extending the shelf life of cut flowers. However, techniques such as dry conditioning and the use of coating films did not show significant results in maintaining commercial quality. It was found that conservative solution research is still the main focus of research at major cut flower technology centers. The meta-analysis highlights the importance of further deepening and/or improving research on techniques that have shown less effective results, and developing new technologies to prolong the vase life of floral stems in order to improve post-harvest quality.","PeriodicalId":19699,"journal":{"name":"Ornamental Horticulture","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67337254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phenological processes occurring during the crop cycle are controlled by endogenous mechanisms and the environment, which in turn influence the duration and occurrence of the development phases. This study aimed to analyze the effect of planting dates (Feb 15, March 19, April 16, May 21, and June 21, 2021) on the occurrence and duration of the development phases of two freesia varieties (Blue Bayou and Yvonne). The trial was conducted in a high tunnel. The crop cycle was divided into vegetative, reproductive, and senescence phases. The number of leaves was counted daily. The development phases were significantly shortened with the delay of planting. The vegetative phase ranged between 2269.78 ± 19.22 and 736.50 ± 19.22 GDD for Blue B., and between 1864.48 ± 19.22 and 667.09 ± 19.22 GDD for Yvonne. The reproductive phase lasted 459.50 ± 20.99 and 379.51 ± 20.99 GDD for Blue B., 461.43 ± 20.99 and 487.29 ± 20.99 GDD for Yvonne. The senescence phase was shortened with delayed planting dates only for Yvonne. Plants cultivated at later dates (May 21, and June 21), and consequently exposed to increased photoperiod, had a lower number of leaves at flowering (7.85 ± 0.10) and were less exposed to inductive temperatures than plants cultivated earlier. The transition to the reproductive phase was determined by the interaction between photoperiod, temperature and plant age.","PeriodicalId":19699,"journal":{"name":"Ornamental Horticulture","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67337267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to analyze the impact of monochromatic lights such as light emitting diode (LED) on the in vitro development of Cattleya walkeriana G. and their effects on acclimatization. The plants were developed in vitro under the colors of green, blue, yellow, red, 2 red:1 blue, and white LED lights. For in vitro cultivation, Knudson medium was used, supplemented with 20 mg L-1 sucrose, 5.5 mg L-1 agar, 2% activated charcoal, 100 mL coconut water, and pH 6.0. For ex vitro cultivation, the plants were acclimatized in styrofoam trays containing sphagnum as a substrate. In general, the supplied light lengths impactedin vitro growth and acclimatization analyses. There was influence on the cuticle thickness of plants in vitro. Chlorophyll and carotenoid contents were not significant. We can conclude that light lengths formed by 2 red:1 blue, red and yellow LEDs can be indicated for better performance in the production of C. walkeriana. The 2 red:1 blue and red LEDs provide superior in vitro development than the others, with gains for the species in acclimatization. The yellow LED provided a possible in vitro hardening, which ensured the greatest success of the seedlings during acclimatization.","PeriodicalId":19699,"journal":{"name":"Ornamental Horticulture","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67337097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was installed in a greenhouse, with 50% shading. The experiment adopted a completely randomized design in a factorial scheme with plots subdivided in space, with the main plots composed of two densities (15 and 30 plants m-2) and the subplots of four temperatures of the nutrient solution (20, 25, 30 °C and uncontrolled temperature) with three replications each. The variables analyzed were plant height, stem diameter, internal and external diameter of the flower, number of leaves, number of buds and flowers, dry and fresh root mass, dry and fresh shoot mass, and cultivation cycle. The data were submitted to an analysis of variance using the statistical software SISVAR. The density of 15 plants m-2 proved to be more efficient, presenting plants of commercialization standard.
