“…In context of treatment of GA 3 200 ppm showed minimum days to colour show (84.94 days) and combine effect of treatment of GA 3 and corm division showed that minimum days to colour showed was observed in 4 bud and 200 ppm GA 3 (81.28 days) which was significantly higher than other treatment combination during experimentation. Similar observation has also been made by Parween et al [11] in gladiolus and Kapri et al [12] in lily. and Asil et al [15] in gladiolus.…”

This study was conducted to assess the response of Gibberellic acid and corm division on floral attributes of gladiolus cv. Punjab Dawn at Horticulture Research Farm of Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, India during two consecutive year (2017-2019). The treatments comprised of growth regulators with two concentration i.e. GA3 100 ppm and 200 ppm including control (distilled water) and corms which are cut having 1bud, 2 buds and 3 buds and whole corm having 4 buds, 5 buds and 6 buds. The experiment was laid out in Randomized Block Design and three replications. The flowering characteristics of Gladiolus are mainly affected by higher concentration of GA3 (200 ppm) as well as whole corm under natural climatic condition. Regarding flowering parameters, it was found that GA3 200 ppm and whole corm i.e. 4 bud, 5 bud and 6 bud influence the quality and quantity parameters, viz. days to spike emergence, days to colour show, days to opening of florets, days to open florets without withering of basal floret, number of florets per spike, longevity of spike, length of spike and rachis (cm) and diameter of florets (cm) as compared to other treatments of GA3 100 ppm and control (distilled water) and cut corms which have 1 bud, 2 buds and 3 buds.

The viability of the mini-cutting technique requires seedling regrowth ability and continuous propagule production. It is hypothesized that the application of gibberellic acid (GA) can stimulate vegetation and increase the production of mini-cuttings. The aim of this study was to increase the mini-cutting yield of Psidium guajava (L.) × Psidium guineense (Sw.) (‘BRS Guaraçá’) as a function of foliar application of GA and season of the year. The experiment was laid out in a randomized-block design with split-plots in time, in which the plots consisted of different GA concentrations applied (0, 50, 100, 150 and 200 mg L-1) and the subplots were represented by two application periods or seasons (summer and winter). Four replicates were used, with two plants per plot. After the seedlings were topped, GA was applied at different concentrations and the emerged shoots were evaluated over 30 days. Mini-stump yield was assessed by collecting and evaluating the potential number of mini-cuttings. Shoot length and mini-stump yield increased linearly with the increasing GA concentrations during the summer. In the winter, this response was quadratic, with optimal concentrations estimated at 65.3 mg L-1 for shoot length and 76 mg L-1 for mini-stump yield. The GA concentration of 200 mg L-1 provided shorter internodes in the summer, whereas in the winter the use of GA did not interfere with this trait. The increasing applications of GA induced a linear increase in stem diameter at both seasons of the year. Gibberellic acid did not interfere with the rooting of the mini-cuttings. The highest rooting percentage occurred in the summer, with an average of 95%. In the winter, this value was 77.2%, demonstrating that mini-cuttings are a promising technique for ‘BRS Guaraçá’. Foliar spraying of GA promoted an increase in mini-cutting production, without interfering with their rooting.
