“…When translated in terms of yield of corms per unit stock, plantation with quarter corms, showed maximum increase in yield over control (no improved cultural technique), followed by that with half corms. Memon et al (2009a) almost obtained the same results by using half corms. They obtained half corms from whole corms with diameter of 3.6 to 3.8 cm ( Figure 3).…”

“…A number of improved techniques are used to promote corm and cormel production in Gladiolus. The research work was reported on divisions of the corms (Singh and Dohare, 1994;Memon et al, 2009a), removal of flower spikes (El-Gamassy and Sirry, 1967;Wilfret and Raulston, 1974;Mukhopadhyay and Das, 1977; Sprouting on the basis of number of sprouts (Source: http://www.shutterstock.com/pic-3075215/stock-photo-one-gladiolus-flowerbulb-brightly-lit-isolated-on-white.html). al., 1978;Misra, 1994;Singh and Dohare, 1994;Memon et al, 2009a), leaf clippings (Misra, 1994;Memon et al, 2009a), corm sizes (Farid Uddin et al, 2002;Memon et al, 2009b), manual removal of apical buds (Singh and Dohare, 1994) and mechanical removal of sprouts in succession during storage (Sharga and Basario, 1976;Misra, 1994).…”

Gladiolus is an important estimated 8th in the world cut flower trade's cut flower grown throughout the world for its elegant attractive spikes of different hues and good keeping quality. The commercial cultivation of Gladiolus is based on natural multiplication of corms and cormels. However, multiplication rate of corms and cormels is slow and the conventional method of propagation is insufficient to meet the demand of planting material and eventually affect the final cost of corms. A number of improved conventional techniques including division of the corms, removal of leaf and flower spikes, use of standard corm size, and mechanical removal of sprouts can increase the multiplication rate of corms and cormels. These improved conventional methods of propagation are insufficient to meet the demand of planting materials. In vitro techniques are applicable for the propagation of corm producing species. These techniques are adopted at commercial level in order to fulfill supply gap of huge demand. A number of in vitro protocols have been developed for regeneration of Gladiolus plantlets using different media by using various explants sources of the plant. However, literature is rather scanty on in vitro cormel formation and acclimatization of in vitro propagules.

“…The previous observations showed the clonal growth in Gladiolus cultivars (Rameau & Gouyon, 1991) and its great enhancement after the clipping of leaves and inflorescences (Memon et al, 2009) or the adding of fertiliser (Ali et al, 2014;Saeed et al, 2014;Khattab et al, 2016). Successful clonal growth was also observed in other tuberous taxa such as Dicentra canadensis (Lin et al, 2016) and Crocus sativus (Negb et al, 1989).…”

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.

“…Gladiolus (Gladiolus x grandiflorus), which belongs to the Iridaceae family, is cultivated in all world and has a great importance in the international market of flowers (MEMON et al, 2009;MAHASEN et al, 2015). It is a cut flower propagated by corms (SCHWAB et al, 2015a), which is a propagative material in high demand in the foreign market.…”

The gladiolus is an important cut flower that is cultivated in all parts of the world, and it is very appreciated to be used in floral arrangements. The growing concern with the environmental contamination and the look for production with higher quality have resulted in increasing the number of studies on the use of organic inputs and microorganisms in floriculture, in particular, the vermicompost and the Trichoderma sp. This work was conducted with the objective to evaluate the development and the quality of gladiolus floral stems in function of the use of vermicompost and Trichoderma sp. applied to the substrate. The experiment was conducted in a greenhouse during the period of August to December of 2015. It was done by utilizing four treatments: T1 = control substrate (50% soil and 50% commercial substrate Carolina Soil); T2 = vermicompost (40%) and control substrate (60%); T3 = Trichoderma sp. added to the control substrate; T4 = Trichoderma sp. added to the vermicompost (40%) and control substrate (60%). The gladiolus variety used was the Peter’s Pears. The variables analyzed were main plant height, Falker chlorophyll index, length and diameter of the main stem, tassel length, quantity of main stem florets, proportionality between tassel and stem, and time until the start of flowering. It was concluded that the development and the quality of the gladiolus floral stem were favored by the use of vermicompost in the concentration of 40% added to the substrate.
