“…e results of the present study showed that GA 3treated corms exhibited a remarkable increase in vegetative growth parameters (number, length, and surface area of leaves) compared to controls. ese results are supported by those reported by several authors on several crops [36][37][38][39].…”

The present study was conducted to evaluate the influence of gibberellic acid (25, 50, 100, and 200 ppm) applied on saffron corms previously harvested during different periods (March, June, and before planting) on the growth and the quantitative and qualitative yield of saffron (Crocus sativus L.). The study was carried out in the field during the 2016-2017 and 2017-2018 seasons in the experimental station of the Faculty of Sciences of Oujda (Morocco). The measured parameters correspond, on the one hand, to morphometric measurements and to the determination of the saffron stigma yield and, on the other hand, to the evaluation of the quality of the spice. The results showed that almost all the parameters studied were significantly affected by the factors considered. The treatment of corms just before planting with concentrations of 100 and 200 ppm GA3 showed the highest flower and leaf appearance rate and the highest leaf length and surface area. Moreover, the application of GA3 during the month of March gave the best results in terms of stigmata yield, percentage of large-diameter daughter corms, and the ratio of the number of flowers produced to the total weight of corms. The results of the coefficient of corm propagation revealed that the application of gibberellin during any period improved this coefficient compared to the control. The results indicated that the application of GA3 with concentrations above 25 ppm can improve the growth of saffron and increase its yield under the semiarid climatic conditions of eastern Morocco.

“…These results are also recorded in our experiment where in some cases the three varieties behaved differently. Moreover, in some experiments plant growth retardants are recommended to be used after one week of pinching [48,49].…”

Enhance Growth and Flower Quality of Chrysanthemum indicum L. with Application of Plant Growth Retardants

et al. 2021

Ornamental plants are cultivated worldwide. Chrysanthemum is classified as one of the most important cut and potted flowers in most of the countries. The consumer’s expectation is to find small–compact, and full of inflorescences plants. To meet these demands, growers are tending to use plant growth retardants. Three Chrysanthemum indicum L. varieties (‘Smola White’, ‘Arber’ and ‘Vienna White’) were assessed by using four plant growth regulators (PP–Bumper 250 EC; CC–Stabilan SL; MP–Medax Top SC; and PD–Toprex SC). Results indicate that treated plants show significant decrease in the assessed parameters, although in some cases growth could be a variety–dependent factor. It can also be concluded that retardants inhibit chrysanthemum growth. PD treatments greatly inhibited the growth of the plant, and also had a negative effect on inflorescences. In conclusion, the present work strengthens the possibility of using retardants as plant growth inhibitors in Chrysanthemum cultivation.

“…It is one of the most complexes in behavior, occurring in soil health, air and water in organic and inorganic forms [12][13][14]. For this reason, it poses the most difficult problem in making fertilizer recommendations [15,16]. Potassium (K) is a major plant nutrient, which is needed by the plants in large amount and is supplied by the K fertilizers Dotaniya et al Sulphur is reported from two natural growth regulators viz., thiamine and biotin.…”

A study on the effect of plant growth regulators on growth of chrysanthemum was carried out at K.N.K. College of Horticulture, Mandsaur. Experiment was laid out in completely randomized design(CRD) with three replications. Chrysanthemum cultivar- Hybrid-2 was used for the experiment. Six PGR treatments consisting of three concentrations each of GA and NAA i.e., GA3 (100, 150 & 200 ppm) and NAA (75 ppm, 125 ppm and 200 ppm) were applied to the experiment. GA3 (200 ppm) recorded the maximum values for plant height, plant spread, number of branches / plant, number of leaves/ plant, leaf length (cm), leaf stalk length (cm), number of suckers per plant, number of flowers per plant, flower stalk length (cm), flower diameter and flowering duration as well as the earliest first flower bud appearance and first flower opening. This treatment also recorded the longest vase life of cut flowers (days), the maximum total water uptake in vase and the maximum diameter of fully opened flower in vase life.
