“…orientalis, flower buds were observed under dissecting and optical microscopes (Zhang et al, 2011). The exact time of the transition from vegetative to flowering stage is of great importance in all flowering plants because it strongly impacts growth synchronization ( Ramzan et al, 2014). The growth phase stages act as developmental landmarks and stimuli for collecting morphological data of interest at any specific stage of plant development (Boyes et al, 2001).…”

The flower initiation stage is one of the most critical stages in plant development. This study was conducted with an aim of identifying the precise flower bud initiation stage in oriental lily hybrids, 'Sorbonne' and 'Siberia', for the purpose of proper plant management during the flower development stage. The bulbs were micro-dissected 0, 10, 20, 30, and 40 days after planting. Five bulbs were randomly selected for dissection and flower bud initiation stage identification. Bulb circumference, shoot length, number of bulb scales, number of leafy scales, number of true/alternate leaves, and flower bud initiation stage were measured. The flower bud initiation stages were scaled as follows: 0 = no flower buds, 1 = starting stage, 2 = flower bud developing stage, and 3 = fully developed flower bud stage. In both the hybrids, flower bud initiation started 20 days after planting and was observed to be associated with shoot length; the initiation occurring in shoots 11-13cm long. It was also greatly affected by the cultural management during the growing of plants. Identification of the exact time of flower bud initiation will be useful in proper management of the plant materials with respect to their requirements of water, nutrient, environmental conditions, and pest control. This knowledge will help in developing quality flowers of the two studied oriental lily hybrids for breeding and commercial purposes.

“…Among the gibberellins, the gibberellic acid (GA 3 ) is best known for breaking the dormancy of seeds, bulbs and tubers, stimulating the flower bud production, elongating flower stems and anticipating flowering (Ramzan et al 2014). Many of these effects have been observed in bulbous ornamental plants such as calla (Miller 2012), gladiolus (Bhujbal et al 2014, Aier et al 2015 and tulip (Ramzan et al 2014).…”

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.

“…Various attributes of ornamentals improved by exogenous application of PGRs: The exogenous application of PGRs has been reported numerous times in various ornamental plants including gladiolus (Sajjad et al, 2015), tulip (Ramzan et al, 2014), dahlia (Mahgoub et al, 2011), lily (Currey and Lopez, 2010), iris (Leeson and Harkess, 2006) etc. Their application was restricted in scientific experiments initially, but later on, was started to use on commercial farms and now is being applied by the progressive growers to improve different characteristics in ornamental plants.…”
