“…With gladiolus, the main effect of temperature was on the rate of development to anthesis. Short photoperiods and elevated temperatures promoted rapid flowering, except during the summer, when high temperature promoted rapid flowering regardless of the photoperiod (Halevy, 1985;Shillo and Halevy, 1976). A similar reduced sensitivity to photoperiod during warm summer conditions has been suggested for Liatris (Grower Books, 1980;Kofranek, 1980;Mevel, 1983;Waithaka, 1985).…”

Additional index words. cut flower, soil temperature, stem elongation, long day, short day Abstract. Shoot emergence of cold-treated Liatris spicata Willd. corms was inhibited by SC soil, delayed at 10 or 15C (7 and 5 days, respectively), and promoted at 20, 25, or 30C. Within 15 days after planting, soil at 20C promoted the highest percentage of shoot emergence (81%). Plants were grown during the first 35 days after emergence under a combination of temperature and long or short days. Flowering shoot length was increased by either short days (8 hours; SD) at 13 or 15C or a 4-hour incandescent night interruption (NI) at 18C. When planted in May, a NI at 15 or 18C decreased the time to harvest by up to 14 days, whereas in November increasing the temperature to 18C, regardless of photoperiod, decreased the days to harvest by 16 days. Plants grown during the first 35 days after emergence under natural days at 15C then placed at 13, 15, or 18C under NI until harvest did not respond to the increasing temperature. Temperature and photoperiod influence Liatris development primarily during the first 35 days of development.

“…A temperatura mínima absoluta, durante o experimento 2, foi -0,8ºC, enquanto a temperatura máxima absoluta foi 39ºC e 39,2ºC para os experimentos 1 e 2, respectivamente. Vários trabalhos, ainda na década de 1970, mostraram que variações nas condições ambientais, o que inclui a temperatura, podem influenciar o desenvolvimento e a produção de hastes florais de gladíolo (Shillo & Havely, 1976a;Shillo & Havely, 1976b;Shillo & Havely, 1976c;Shillo & Havely, 1976d). Barbosa (2011) reporta, ainda, que o gladíolo pode ser cultivado ao longo de todas as épocas do ano, porém, em alguns períodos, poderão ocorrer problemas de cultivo, principalmente se houver redução de luminosidade e temperatura, condições típicas do período invernal de regiões subtropicais.…”

“…Estudos clássicos em ambiente controlado mostraram a influência de fatores ambientais sobre o desenvolvimento e a produção de hastes de gladíolo, tais como intensidade luminosa, comprimento do dia, temperatura, umidade, além da interação entre eles (Shillo & Havely, 1976a;Shillo & Havely, 1976b;Shillo & Havely, 1976c;Shillo & Havely, 1976d). Nesse contexto, a época de plantio desempenha importante papel no crescimento e na qualidade das hastes florais de gladíolo (Zubair et al, 2006;Ahmad et al, 2011;Akpinar & Bulut, 2011).…”

Resumo -O objetivo deste trabalho foi determinar as épocas de cultivo, em ambiente subtropical, em que é possível produzir hastes de gladíolo (Gladiolus x grandiflorus) que atendam aos padrões comerciais quantitativos do mercado nacional de flores de corte. Dois experimentos de campo foram realizados, um de agosto de 2011 a julho de 2012 e outro de agosto de 2012 a julho de 2013, com três cultivares do gladíolo e 12 datas de plantio para cada experimento. O comprimento total da haste, o comprimento do pendão e o diâmetro da haste foram avaliados quando as hastes estavam em ponto de colheita, ou seja, quando a cor das pétalas apareceu nos três primeiros floretes na base da haste. Os melhores meses para a produção de hastes de gladíolo são julho, agosto, setembro, fevereiro, março e abril, embora em nenhuma das datas de plantio tenham sido produzidas hastes com parâmetros quantitativos abaixo do padrão mínimo (exceto em períodos com geada, durante o espigamento).Termos de indexação: Gladiolus x grandiflorus, época de cultivo, floricultura, padrão comercial, qualidade.

“…In addition, Wright and Burge (2000) observed that symptoms of water stress include lower growth, what is much apparent in this study. Furthermore, Shillo and Halevy (1976b), Bastug et al (2006), andPereira et al (2009) mentioned that gladiolus vegetative development and flower stem initial growth are the most sensitive stages to soil water shortage. In fact, water deficit permanently affected plant development as, although plants remained alive, such treatment did not promote any flowering, as also reported by Shillo and Halevy (1976a) for gladioli cultivated under low soil moisture.…”

Management of corm size and soil water content for gladiolus flower production

Gladiolus grandiflorus Andrews, in the family Iridaceae, is one of the most produced and marketed flowers in the world. In general, however, research results on gladioli production factors are scarce and divergent. The objective of this work was to evaluate the influence of corm size and soil water content on gladiolus flower production. The experimental design, using the early maturity cultivar 'White Friendship', was entirely randomized, arranged in a 5 x 2 factorial scheme (five soil water contents: 25; 50; 75; 100; and 125% field capacity, combined with two corm sizes: medium and big), with four replications per treatment. Each replication, composed of one pot, comprised three corms, totaling 40 pots and 120 plants. Both vegetative and flowering characteristics were evaluated. Gladiolus cultivation at 80% soil field capacity presents best results for commercialization, generating longer flower stems with greater diameter and flower number, plus larger flowers. Furthermore, such soil water content promotes the shortest cultivation period.
