“…due to heavy competition between the plants of golden rod due to which the juvenile phase of the plant might have been extended. The results are in close agreement with the findings of Osman and Sewedan (2014) [5] in golden rod who also reported delay in flowering due to increased planting density.…”

“…The plants planted at wider spacing of 30 x 40 cm produced good vegetative growth, thereby proper development of ~ 761 ~ required photosynthetic system which might have helped to increase the production of flowers which in turn resulted in maximum number of panicles plant -1 and ha -1 . Similar results have also been reported by Osman and Sewedan (2014) [5] in golden rod.…”

“…The increase in growth parameters with GA3 treatment over control might be because of the fact that GA3 promotes vegetative growth by inducing active cell division and cell elongation, which might have resulted in increasing the growth parameters. These findings are also supported by Bharathi et al (2009) [1] in tuberose, Nandre et al (2009) [4] in China aster and Osman and Sewedan (2014) [5] in golden rod.…”

An experiment entitled "Effect of spacing and GA3 on growth, flowering and yield of golden rod" was carried out during Kharif season of the year 2019-2020 at Satpuda Botanical Garden, Horticulture Section, College of Agriculture, Nagpur, Dr. PDKV, Akola (M.S.). The treatments comprised of four spacing viz., 30 x 10 cm, 30 x 20 cm, 30 x 30 cm and 30 x 40 cm and three levels of GA3 viz. 0 ppm (control), 100 ppm and 150 ppm. Before planting suckers of golden rod were dipped in GA3 solution of different concentrations as per the treatment for 6 hours. The experiment was laid out in Factorial Randomized Block Design with three replications. The results revealed that, in respect of growth parameters, plant height with panicle, number of leaves plant -1 and plant spread were recorded significantly maximum with the spacing of 30 x 40 cm and suckers treatment with 150 ppm GA3. In respect of flowering parameters, initiation of panicle and opening of first flower were registered significantly earliest when golden rod suckers planted at the spacing of 30 x 40 cm and treated with 150 ppm GA3. The yield parameters like number of panicles plant -1 and ha -1 were also found significantly maximum with the spacing of 30 x 40 cm and the sucker's treatment with 150 ppm GA3.

An experiment entitled "Effect of planting dates and GA3 on growth, flowering and yield of golden rod" was carried out during Kharif season of the year 2018-2019 at Satpuda Botanical Garden, Horticulture Section, College of Agriculture, Nagpur, Dr. PDKV, Akola (M.S.). The treatments comprised of four planting dates viz., 15 th June, 15 th July, 15 th August and 15 th September and three levels of GA3 viz. Control, 200 ppm GA3 and 250 ppm GA3. Before planting suckers of golden rod were dipped in GA3 solution of different concentrations as per the treatment for 6 hours. The experiment was laid out in Factorial Randomized Block Design with three replications. The results revealed that, in respect of growth parameters, plant height with panicle, number of leaves plant -1 and plant spread were recorded significantly maximum with the planting date of 15 th June and suckers treatment with 200 ppm GA3. In respect of flowering parameters, initiation of panicle and opening of first flower were registered significantly earliest when golden rod suckers planted on 15 th June and treated with 200 ppm GA3. The yield parameters like number of panicles plant -1 and ha -1 were also found significantly maximum with the planting date of 15 th June and the sucker's treatment with 200 ppm GA3.

“…The application of GA 3 had a substantial effect on the vase life, total chlorophyll, and carotene content of leaves in Solidago canadensis L.cv. “Tara” [ 22 ]. GA 3 pulsing improves flower petal water content, and solution uptake increases vase life and other qualitative attributes of cut stems compared with the control and delays the bent neck of cut rose [ 23 ].…”

The postharvest life of cut flowers is limited, which is a major challenge and varies greatly depending on plant varieties, cut flower stage, flower length of the harvested shoots, and storage conditions including postharvest treatments. As a result, improving the vase life and quality of cut flowers in regulating postharvest characteristics and overcoming these challenges is critical to the horticulture business. Novel engineered nanocomposites were created and tested for possible impacts on flower bud opening, postharvest life extension, longevity regulation, and preservation and enhancement of the strength and appearance of cut flowers. The experiment was conducted as a factorial experiment using a completely randomized design (CRD) with two factors. The first factor was two holding solutions (without or with sucrose at 20 gL−1). The second factor was 12 pulsing treatments for 24 h; distilled water as a control, 75 ppm GA3, multi-walled carbon nanotubes MWCNTs at 10, 20, 30, 40, and 50 ppm, and MWCNTs (10, 20, 30, 40, and 50 ppm)/GA3 (75 ppm) composites; each treatment had 3 replicates, for a total of 72 experimental units. In the present study, gibberellic acid (GA3) was synthesized in functionalized (MWCNT/GA3 composites) as a novel antisenescence agent, and their effect on the vase life quality of cut rose flowers Rosa hybrida cv. ‘Moonstone’ was compared by assaying several parameters critical for vase life. The adsorption of GA3 on MWCNTs was proven by performing FTIR spectroscopy which ensures that the formation of the MWCNTs/GA3 composite preserves the nanostructure and was examined by high-resolution transmission electron microscopy (HR-TEM). The results revealed that sucrose in the holding solution showed a significant increase in fresh weight, flower diameter, and vase life by 10.5, 10.6, and 3.3% respectively. Applying sucrose with MWCNTs 20 ppm/GA3 75 ppm composites or MWCNTs 20 ppm alone, was critical for the significant increase in flower opening by 39.7 and 28.7%, and longevity by 34.4 and 23.2%, respectively, and significantly increased chlorophyll a, b, total chlorophyll, anthocyanin, total phenolic content, and 2,2-Diphenyl-1-picrylhydrazyl scavenging activity as compared to the control.
