“…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. According to the same authors, low soil moisture is even more detrimental when temperature is high, as it implies in higher vapor pressure deficit.…”

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.

“…The positive relationship among soil humidity and number and dimensions of shoots, flowers and inflorescences was observed in Gladiolus grandiflorus (Porto et al 2014;Pereira et al 2016aPereira et al , 2016b. The reducing flowering of Gladiolus individuals in effect of decrease of soil moisture was also observed by Shillo and Halevy (1976). The occurrence of the highest generative shoots of Gladiolus imbricatus, as well as the longest inflorescences and flowers in the vicinity of tall-growing neighbours might improve the flower visibility for pollinators from the order Hymenoptera, which are attracted particularly by blue, pink, purple and mauve colours (Kevan & Baker, 1983;Menzel & Shmida, 1993;Miller et al, 2011).…”

Abstract. The investigations, aimed to assess the abundance, stage structure and distribution of shoots, as well as the chosen traits of generative shoots (number of leaves and length of the longest one, height of shoot, length of inflorescence and the dorsal tepal of the lowermost flower, number of seed capsules) of Gladiolus imbricatus L. were conducted in the years 2015-2017. The observations were carried out from Kraków-Pychowice to Tyniec in abandoned moor-grass meadow (Patch I), shrub willows (Patch II), macroforb community (Patch III) and community dominated by tall-growing grasses (Patch IV). The population abundance augmented gradually in subsequent study sites. Additionally, the temporal fluctuations of shoot number were recorded in all the Patches. The similar in consecutive years' stage structure differs among the study sites. The occurrence of juvenile, vegetative and generative shoots in Patch I might suggest the successful seedling recruitment, while the lack of shoots in pregenerative stages in Patches II-IV might indicate the absence of safe sites for the appearance of new genets. The occurrence of clusters of shoots in Patches II-IV might be a consequence of clonal growth. The traits of generative shoots rather did not show the temporal variability, but they presented spatial variability and in most cases augmented from Patch I, via Patches II and III, to Patch IV.The performed studies enabled ascertaining that the population occurring in Patch I presents the best condition despite the lowest abundance of shoots. Also the other, more abundant populations, inhabiting Patches II-IV might persist in the colonised sites thanks to the vegetative multiplication of ramets and maximisation of chances for successful pollination and effective seed dissemination.

“…Anything higher than 27 QC means a greater chance of flower desiccation and crooked stems (Buschman, 1998a). Shillo and Halevy (1976d) reported that gladioli are tolerant of high temperatures (up to 50 QC) as long as the air humidity and soil moisture are at an optimum. They also noted that plants are more sensitive to high temperatures from planting to the first leaf stage and that this damaging effect is indirect through its effect on plant water balance.…”

“…Cool night temperatures, an average temperature below 10 QC and a long cold period, can cause an arrest in the growth and development of the plant (Buschman, 1998b;Imanishi & Imae, 1990;Armitage, 1993). Temperatures between 1 and 4 QC at any stage, increase the occurrence of flower blasting (Shillo & Halevy, 1976d). Gladioli do not tolerate temperatures below freezing point which causes cold damage and even perishing of the crop (Buschman, 1998b).…”
