“…Although the crop may suffer from excess water, which favors corm rot, induces delayed development cycle and reduces plant growth (PEREIRA et al, 2009;MAZZINI-GUEDES et al, 2017), its highest sensitivity is related to water deficit. Some of the symptoms that can be triggered by water deficit include a shorter development cycle, burned spike tips and reduced growth.…”

This work aims to developing an Agricultural Climate Risk Zoning for gladiolus in the State of Santa Catarina. The bioclimatic requirements and the risk criteria were defined for the crop through a bibliographic review. The probability of frost occurrence, water balance and frequency of maximum air temperatures above 34°C were calculated with meteorological database. A maximum assumed risk of 20% was considered. The period when planting is not recommended was determined for each of the development cycles (early, intermediate I and II and late). It was observed that low temperatures and occurrence of frost in autumn and winter limits gladiolus planting in the State of Santa Catarina. Analysis of the water balance indicated there is risk of water deficiency throughout the year, which varies according to the locations. Maximum air temperatures above 34ºC do not occur frequently in the State. In the Coastal regions, there are no restrictions to planting throughout the year. The Agricultural Climate Risk Zoning indicate the potential for gladiolus farming in Santa Catarina, where the greatest planting potential is in the Coastal, West and Extreme West regions.

“…A smaller leaf area can also occur as an adaptation of the plant to water stress conditions, since the decrease in leaf area represents a smaller transpiration surface; thus, avoiding rapid water depletion from soil (Taiz;Zeiger, 2017). When studying the effect of water deficit in gladiolus plants, Mazzini-Guedes et al (2017) observed that plants obtained after applying 25% of field capacity treatment have lower values of total plant height and number of leaves.…”

Water management and meteorological conditions during the cropping phase play an essential role in maintaining the commercial quality of cut flowers. This study evaluates water requirement, sensitivity to water deficit, and commercial quality of gladiolus ‘Amsterdam’ produced with automated irrigation in different growing periods. The experimental design was in randomized blocks with five replicates and consisted of the growing period factors (winter/spring 2018 and autumn/winter 2019) and the irrigation level factors (45% - L1, 60% - L2, 80% - L3, and 100% - L4 of crop water requirement). An automatic irrigation controller was used for irrigation management. At the harvest point, we evaluated the stems for the diameter, number of flowers, spike length, and floral stem length. We also evaluated stomatal conductance, leaf area, and duration of phenological phases on degree-days. The application of 100% crop water requirement using an automatic irrigation controller in the autumn/winter cycle results in better commercial classification. The treatment with 45% of the crop water requirement extended the total duration of the cycle. In conclusion, flower stems of better commercial classification are obtained with 100% of crop water requirement during the autumn/winter cycle.

“…Gladiolus ( Gladiolus x grandiflorus Hort.) is one of the most important bulbous flowers produced worldwide (Becker et al, 2020; Mazzini‐Guedes et al, 2017; Rosa et al, 2014). Marketed mainly as a cut flower for interior decoration (Khanam & Patra, 2015), gladiolus can also be used in landscaping such as in mixed borders, and for ornamenting events or other special dates (Schwab et al, 2018; Tomiozzo et al, 2019).…”

Gladiolus is one of the most important bulbous flowers produced worldwide. The objective of this study was to evaluate the combined effect of irrigation and soil mulching on soil water conservation and its effect on gladiolus floral stem quality. Two field experiments were conducted with gladiolus at the Federal University of Santa Maria, state of Rio Grande do Sul, Brazil, during 2019 and 2020. The experimental design was a completely randomized three‐factor design, with two cultivars (Red Beauty and T704 in experiment 1 ‐ E1 and Red Beauty and Jester in experiment 2 ‐ E2), two cultivation systems (soil mulched with straw and bare soil) and two water regimes (irrigated and non‐irrigated) as treatments. When gladiolus plants reached the R2 stage (harvest point), total stem length, spike length, stem diameter and final number of florets were evaluated. Variables were subjected to analysis of variance and Tukey's test at 5% of error probability. Irrigation improved the quality of floral stems, with greater stem and spike length, greater diameter and number of florets per spike, thus resulting in stems with greater decorative value. The soil covered with straw did not influence the quality parameters of the floral stem of the gladiolus, the only observed difference between cultivars being the variable length of the spike.
