“…The adaptation of radiation and temperature conditions is extremely important for the post-harvest of gladiolus, as reported by Becker et al (2021b). The present work reports on research on how the different cultivation conditions (full sun and 70% shade) affected the gladiolus cultivars Jester and Rose Friendship -from growth to flowering and vase life -cultivated in the semi-arid region of Brazil.…”

“…In the semi-arid region, such as in the Northeast of Brazil, data on the adaptation of fresh cut gladiolus flowers for commercialization is restricted. The studies have been exclusively restricted to conditions in the south of Brazil, such as the recent works of Becker et al (2021a) and Becker et al (2021b). In addition, Becker et al (2021b) carried out a climate risk zoning for gladiolus under climate change scenarios in three regions of Rio Grande do Sul, and showed that the hotter and drier places were a disadvantage to the plants in the Veiling Holambra pattern.…”

Cultivation conditions are determining factors that affect the quality of cut flowers. The objective of this study was to evaluate the vegetative growth, flowering and vase life of commercial gladiolus cultivars under different shading conditions in the Brazilian semi-arid region. Two cultivars of gladiolus (Jester and Rose Friendship) were grown under two conditions: full sun and 70% shade. Biometrics were evaluated 60 days after planting and the growth rate of the crop was evaluated at 15-30, 30-45 and 45-60 days for the variables: number of tillers, stem diameter, number of leaves and plant height. After 45 days, the fresh weight, dry weight and total relative water content of the area and root parts of the plants were evaluated. After the harvest, the stems were kept at a temperature of 22±3 °C and relative humidity (RH) of 60%. Visual assessment, pH of the solution, variation in the volume of water and loss of fresh mass were measured every two days. Cultivation with 70% shading resulted in greater accumulation of biomass in the aerial part of gladiolus plants, greater neck diameter and height. The Rose Friendship cultivar underwent a greater translocation of dry matter to the aerial part of the plants, resulting in greater height. On the other hand, the gladiolus stems from cultivation under full sun conditions resulted in longer vase life, 10 days under conservation conditions at 22±3 °C and RH 60%.

“…Drought is known as a natural disaster that often appears from a persistent deficiency of rainfall compared with the average value over a long time period (Mayowa et al, 2015;Becker et al, 2021), leading to a lack of freshwater for serving life, agricultural activities, and other sectors (CGIAR, 2015;Zarch et al, 2015). Unlike other natural disasters, drought comes silently, but its consequences are extremely large (Miyan, 2015).…”

In recent decades, the rice cultivation regions in the Mekong Delta have continuously suffered from unprecedented weather events due to a decline in rainfall as part of climate variability. The aim of this study was to perform a comprehensive exploration of the rainfall characteristics across the area, applying the Rainfall Anomaly Index (RAI), Spearman Rho test and Sen slope estimator to help track the weather as well as provide warnings on the potential risks caused by alterations in rainfall amounts. For this goal, the rainfall data sequences at 14 national observation stations across the Mekong Delta were collected for the 1984 - 2019 period. Results indicated that the dry weather seasons occurred more frequently during the normally wet weather seasons. Four typical dry weather seasons were identified for the 1997 - 1998, 2002 - 2004, 2014 - 2016, and 2018 - 2019 periods. Among these, the 2014 - 2016 period was the driest, with 9 out of 12 stations in the area being extremely dry and RAI risk peaks as high as -4.86 at the Moc Hoa station in the province of Long An. A weather trend of decreasing rainfall was evident, mainly in the coastal sub-regions. The discovery of changing rainfall trends is valuable for predicting future climate variability.

“…has had expressive gains in recent years, mainly in trade, occupying fifth place in cut flower production in Brazil (Junqueira and Peetz, 2018). It has become a crop of great expression in the country due to the important cut flower for small farmers, for being a crop of easy production, which requires low initial cost and can be grown in an open field (Becker et al, 2021).…”

Currently, floriculture has drawn the attention of farmers as an option for income on their properties. The gladiolus is a culture destined to produce cut flowers, widely used by florists and decorators. Despite its wide use, there is still not much information about the behavior of different cultivars in some places of cultivation in the country and the possibility of producing quality stems. In this sense, the objective of this work was to evaluate the quality of stems from different cultivars of gladiolus in a subtropical environment. The work was performed in the city of Chopinzinho/PR. The experiment was conducted in a randomized block design with five repetitions. The factor studied is represented by cultivars of different cycles of the gladiolus culture, as follows: Red Beauty (intermediate II), White Friendship (early), and Jester (intermediate II). Planting was performed using bulbs, inserted in the soil at an average depth of 10 cm with a spacing of 30 cm between plants and 40 cm between rows. The quality of stems was evaluated by measuring the length of stems, length of the stem, the diameter of the stem, and the number of florets per spike. Also, based on one of the quantitative standards of quality of floral stems established for gladiolus, the plants were classified according to the length and diameter of the stems in the classes: 75, 90, and 110. The data were submitted to variance analysis, and after significant results were found, the data were submitted to mean comparison using the LSD test at a 5% error probability. For the data in relation to commercial classification, descriptive statistics were used. The results show that factors related to climate directly interfere in the development and flowering of gladiolus plants, and the cultivars White Friendship, Red Beauty and Jester express different responses to these factors. In general, the White Friendship and Jester cultivars obtained the best results for stem quality, considering the variables stem length and total length of the stem, length of the stem and diameter of the stem. Even though the cultivar Red Beauty showed lower quality indices, they are still within the commercialization standard for gladiolus. Thus, it is possible to produce gladiolus stems with quality in this environment.
