Temperatura base para abertura de floretes e antocrono em gladíolo 1 O gladíolo é uma flor de corte de grande importância nos mercados nacional e mundial. A haste floral, do tipo espiga, é composta por floretes que apresentam abertura acropetal. O conhecimento da velocidade de abertura desses floretes, representada pelo antocrono, pode auxiliar no planejamento das atividades de colheita e comercialização. Os objetivos deste trabalho foram: estimar a temperatura base para abertura de floretes em gladíolo e determinar o antocrono, com a unidade de tempo representada pela soma térmica. Foram conduzidos dois experimentos de campo, em Santa Maria, RS, durante dois anos (2011 a 2013), sendo cada experimento composto por 12 datas de plantio e três cultivares. A soma térmica diária (STd) foi calculada pela diferença entre a temperatura média e a temperatura base (Tb) e, a soma térmica acumulada, pelo somatório das STd. Para a estimativa Tb para abertura de floretes, utilizaram-se os dados do número de floretes abertos (NFA), coletados nos experimentos. Conclui-se que Tb para abertura de floretes em gladíolo é 6 ºC e que o antocrono é, em média, 14,7 ºC dia por florete, mas varia com a disponibilidade de radiação solar durante o florescimento da espiga.Palavras-chave: Gladiolus x grandiflorus; floricultura; temperatura basal; soma térmica; radiação solar. Natalia Base temperature for florets opening and anthochron in gladiolusGladiolus is an important cut flower in national and international markets. The floral stem, a spike, is composed of florets that have acropetally opening. Knowledge on the speed opening of florets, represented by the anthochron, can assist in planning the harvesting and marketing activities. The objectives of this study were estimate the base temperature for florets opening in gladiolus and to determine the anthochron, with the time unit represented by the thermal time. Two field experiments during two years (2011)(2012)(2013), each experiment composed of 12 planting dates and three cultivars, were conducted in Santa Maria, RS, Brazil. The daily thermal (STd) was calculated as the difference between the daily mean temperature and the base temperature (Tb), and the accumulated daily thermal was obtained by the sum of STd. To estimate the Tb to florets opening, we used the number of open florets (NFA) collected in the experiments. We concluded that the Tb for florets opening in gladiolus is 6 °C and the anthochron is, on the average, 14,7 ºC day per floret, but the anthochron varies according to the solar radiation during the spike flowering period.

“…As not all plants reached R2 on the same day, as the flowering period occurs within 15 days, farmers took the first stems to the fair one week before Mother's Day. An alternative for farmers with cold rooms in the property is the storage of the stems at low temperatures (approximately 6°C) to delay the opening of the florets until the day before the day of sale (Schwab et al, 2015b). However, since none of the farmers had a cold room, they started marketing at the fairs about a week before the intended date, using them as an attraction for consumers to return to the fair next week to buy flowers for Mother's Day.…”

“…In Brazil, All Souls' Day is the main date for the commercialization of gladiolus (Schwab et al, 2015a) and, because of this cultural factor, many farmers believe that cultivation of this species is possible only in late winter and early spring (July, August and September). However, the late summer and early autumn (February, March and April) is also a suitable period for the production of quality flower stems (Schwab et al, 2015b). In the RS, the demand for gladiolus has been increasing in different celebratory dates, such as Mother's Day, Women's Day and also for the ornamentation of interiors, parties and events (Schwab et al, 2018).…”

Flower crops are an alternative for diversification in small farms, being gladiolus an option of cut flower. The objective of this study was to disseminate the gladiolus crop as an alternative for diversification and profit for small farms through an extension project where crop management practices were demonstrated during its development cycle. An extension project was carried out in partnership with a rural extension agency, EMATER/RS-ASCAR, to identify the farmers interested in diversifying their production system for growing gladiolus. The extension project was developed in four counties in the Central region of the Rio Grande do Sul/Brazil. Together with the extensionists of EMATER/RS-ASCAR, farmers were assisted during the entire production cycle and learned the management practices from planting to harvesting. Altogether, approximately 2,400 gladiolus spikes were produced, which were marketed one week before and during Mother's Day week at local fairs. In all the counties, the demand and consumption of the flower stems were high, demonstrating acceptance of the consumers of gladiolus stems on Mother's Day. The gladiolus production has proven to be profitable for small family properties. This system encourages the production in short-chains, contributes to the growth of local flower production and may contribute for decreasing rural exodus and sustainability for future generations. ResumoA cultura do gladíolo como alternativa de diversificação e renda na pequena propriedade familiar O cultivo de flores é uma alternativa de diversificação de produção e renda para as propriedades familiares, sendo o gladíolo uma opção de flor de corte. O objetivo deste trabalho foi divulgar a cultura do gladíolo como alternativa de diversificação e renda para pequenos produtores rurais através de um projeto de extensão onde foram demonstradas as técnicas de manejo da cultura durante o seu ciclo de desenvolvimento. Para isso, foi firmada uma parceria com a instituição de extensão rural EMATER/RS-ASCAR, com o intuito de identificar produtores interessados em cultivar o gladíolo em suas propriedades. O projeto de extensão foi desenvolvido em cinco municípios da região da Depressão Central do Rio Grande do Sul. Juntamente com os extensionistas da EMATER/RS-ASCAR, foi acompanhado o ciclo de desenvolvimento do gladíolo, indicando aos produtores as principais técnicas de manejo do plantio à colheita. Ao todo, foram produzidas aproximadamente 2400 hastes de gladíolo, que foram comercializadas em feiras locais no Dia das Mães. Em todos os locais houve grande procura e consumo das hastes florais, demostrando aceitação do consumidor por hastes de gladíolo para o Dia das Mães. Esta atividade demostrou ser rentável aos produtores familiares. Este sistema de produção incentiva a produção em cadeias curtas, contribui para o crescimento da produção local de flores e pode contribuir para diminuir o êxodo rural e a sustentabilidade das futuras gerações no campo.

“…The stems were classified as long (90 cm) (Tombolato et al 2010), with spikes of 44.03 cm, on average, corresponding to 48.9 % of the stem length. According to Schwab et al (2015b), the distribution of florets on the stem becomes aesthetically pleasing when the ratio is above 40 %. Stem diameter indirectly indicates stem resistance.…”

Gladiolus is an important cut flower commercialized in Brazil, and the use of gibberellic acid (GA3) to cultivate it in a protected environment may promote the production of high quality flower spikes. This study aimed at evaluating the production of flower spikes and corms of gladiolus ('White Friendship' cultivar) submitted to high concentrations and application methods of gibberellic acid, in a protected environment. The experimental design was randomized blocks, in a 2 x 4 factorial arrangement, being two application methods (foliar spraying and corm soaking) and four concentrations (0 mg L-1, 250 mg L-1, 500 mg L-1 and 1,000 mg L-1) of gibberellic acid, with six replications and two plants per experimental unit. The following traits were evaluated: plant height, number of leaves per plant, marketable harvest point of flower spikes, number of florets per flower spike, flower panicle length, stem and floret diameter, corm perimeter, number of cormels per plant and production of corm fresh matter and leaf dry matter, flower spikes, corms and cormels. High concentrations of GA3 are not recommended for the production of flower spikes and corms of the gladiolus 'White Friendship' cultivar. The corm soaking application method anticipates the harvest of flower spikes and produces a higher number of cormels per plant. Regardless of the application method, the concentration of 550 mg L-1 of GA3 increases the cormel yield of the 'White Friendship' cultivar.
