“…While the lowest seed weight per spike was observed by the cross H 18 Punjab Beauty × GS-2 (0.9 g) and H 3 Arka Amar × Arka Kesar (1.0 g). Poon et al (2009) are quite different from that of the recent study most presumably due to the inclusion of different genotypes as male parents in crosses, As low temperature and low light intensity leading to the activation of inhibitors in pollen tube, occurrence of flower abortion, and inclusion of variety are responsible factors to cause impediments in getting success of capsule and seed set in intervarietal crosses of flower bulbs.The success of hybridization depends on the selection of parents and their genotype Michurinsk (2014). During cloudy weather or poor sunshine, there was very poor photosynthetic activity hence the amount of sucrose for pollen germination and pollen tube growth may be insufficient Mahawer et al (2011).…”

“…Asynchrony in such flower characteristics could be an impediment to plant breeders for hybridization. Therefore, the knowledge of floral biology is the pre-requisite for undertaking hybridization programme so that maximum number of viable seeds in capsule may be produced in shortest possible time (Poon et al, 2009;Mahawer and Misra, 1993). Hybridization in gladiolus is carried out to develop new cultivars with improved trait like spike length, novel colour, desired size florets per spike, compactness and vase life.…”

Thirty-five intervarietal crosses of gladiolus were tested separately in RBD, each with 3 replication in the ACRIP Floriculture, Department of Horticulture, RCA, Horticulture farm Udaipur from 2019-20. The objective of the study was to find the potentially of seed set in different crosses. Under intervarietal crosses, high capsule set per spike resulted in 'H 11 -GS-2 × Arka Amar (5.42), H 12 -GS-2 × Priscella (5.35), H 1 -Anglia × Priscella (5.16), H 13 -GS-2 × Punjab Beauty (5.14), H 9 -Chandani × Punjab Beauty (5.10), H 24 -Pusa Gunjan × Arka Kesar (5.10) and H 25 -Pusa Gunjan × Arka Pratham (5.00) per spike., but 'H 3 -Arka Amar × Arka Kesar (1.34), H 18 -Punjab Beauty × GS-2 (1.40) and H 33 -Pusa Subham × Nathan Red (1.50) produced the lowest capsule set per spike. 'H 13 -GS-2 × Punjab Beauty' resulted the highest weight of capsule per spike (70.22 g) followed by 'H 11 -GS-2 × Arka Amar' (61.75g). While the lowest in cross 'H 3 -Chandani × Arka Amar' (13.91 g). 'H 25 Pusa Gunjan × Arka Pratham' produced maximum number of seed per capsule (55.00) followed by 'H 11 -GS-2 × Arka Amar' (54.00). While 'H 3 -Arka Amar × Arka Kesar' the poor seed setting (9.00). The maximum number of seed set per spike in 'H 11 -GS-2 × Arka Amar' (298.10) followed by the cross H 24 -Pusa Gunjan × Arka Kesar (239.70), whereas lowest number of seed set per spike in 'H 3 -Arka Amar × Arka Kesar' (12.06). 'H 25 -Pusa Gunjan × Arka Pratham' gave highest seed weight per capsule (2.10 g), while lowest in 'H 30 Pusa Kiran × Punjab Beauty (0.30)'. 'H 25 -Pusa Gunjan × Arka Pratham' produced highest seed weight per spike (10.6 g) followed by 'H 11 -GS-2 × Arka Amar' (8.8 g) and 'H 18 -Punjab Beauty × GS-2' produced lowest seed weight per spike (0.9 g)

“…Additionally, they are used in Brazil for ornamentation of ceremonies and general decorations, where All Souls' Day is its peak in sales (SCHWAB et al, 2014). New varieties are produced through hybridization, in which show a high variability in the days of flowering (POON et al, 2009), variety of shapes, colors, and size of inflorescence (TOMBOLATO et al, 2005).…”

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.
