“…1-Naphthaleneacetic acid, commonly abbreviated NAA is an organic compound with the formula C 10 H 7 CH 2 CO 2 H. NAA is a plant hormone in the auxin family and is an ingredient in many commercial postharvest horticultural products. It is also a rooting agent and used for vegetative propagation of plant from stem and leaf cutting (Dimitrios et al, 2008;Saifuddin., 2009). 6-Benzyladenine is a synthetic cytokinin that stimulates cell division in plants.…”

Flower craft is one of the most flourish and dynamic enterprises in today's world. Tinting or artificial colouring of tuberose may be a potential value addition venture. Tuberose (Polianthes tuberosa L.) is a popular cut flower having white coloured fragrant blooms. Postharvest losses in many cut are estimated to be as high as 40% in the absence of floral preservatives. Blockage of vascular bundles due to microorganism proliferation is one of the reasons for cut flower postharvest losses. Therefore in this experiment effect of different biocides on kind and proliferation of microbes in vase solution of tinted tuberose were studied. In present experiment five different food dyes were used as tinting agent likes Blue, Apple green, Lemon yellow, Orange red and Rose pink at a concentration of 1%. Therefore an inspection was carried out to study the effect of different biocides (Calcium hypochlorite solution of 750 ppm, Sodium hypochlorite solution of 750 ppm, Benzyl adenine 450 ppm and Naphthalene acetic acid 250 ppm) on value addition and vase-life of tinted tuberose cv. Prajwal. In which flowers remained maximum fresh with higher vase-life in Lemon yellow followed by Rose pink and Apple green. Results suggest that among all chemicals Calcium hypochlorite (750 ppm) was best followed by Sodium hypochlorite (750 ppm), Benzyl adenine (450 ppm) and Naphthalene acetic acid (250 ppm).

“…12 Also gibbrellic acid (GA 3 ) plays a beneficial role in the longevity of many species of ornamental plants. 13 As chrysanthemum is a famous winter flowering plant, the study was conducted to elaborate its ornamental and aesthetic value under the agro climatic conditions of Peshawar. To study the performance of best chrysanthemum cultivar under agro climatic condition of Peshawar for cut flowers and the response of pre-harvest treatment of gibbrellic acid (GA 3 ) on vase life of chrysanthemum flowers.…”

The pre-harvest treatment of gibbrellic acid (GA 3) as foliar spray was applied to chrysanthemum cultivars in order to investigate its impact on flower quality, persistency on plant and vase life. The Randomized Complete Block Design (RCBD) with two factors factorial arrangement was used with foliar application of GA 3 (0, 50, 100, 150mgL-1) sprayed on chrysanthemum cultivars (Rebbonet, Revert, Resomme and Magdalena) at button stage of flower buds. The foliar application of GA 3 significantly influenced most of the growth parameters and enhanced the quality of flowers in chrysanthemum cultivars. However, the chrysanthemum plants when treated with gibbrellic acid (GA 3) at the rate of 100mgL-1 resulted in maximum bud size (2.29cm), flower size (13.91cm), flower persistency on plant (51.14days), fresh flower weight (14.66g), dry flower weight (6.03g) and vase life (37.15days). The cultivar Rebbonet showed the highest bud size (2.28cm), flower size (12.20cm), number of days to flower persistency (47.00), fresh flower weight (12.45g), dry flower weight (5.08g), vase life (31.00days) and the least percent flower petal fading (9.69%). The foliar application of gibbrellic acid at the rate of 100 mg L-1 significantly influenced the growth and quality flower production of chrysanthemum cultivar Rebbonet. It was concluded that the cultivar Rebonnet could be sprayed with foliar application of gibbrellic acid (GA 3) at the rate of 100 mg L-1 to obtain quality flowers under the agro climatic condition of Peshawar,

“…GA 3 sprays enhanced plant dry mass, leaf area, plant growth rate and crop growth rate in Mustard (Khan et al, 2002). Saifuddin et al (2009) reported that Bougainvillea bracts were sprayed with GA 3 (100 ppm), Maximum bract weight and shoot length were observed but bract longevity no increased in GA 3 (100 ppm) treatment. Therefore, our hypotheses for this study were effects of different regulators, on the growth of Polianthes tuberose.…”

Effect of different chemical treatments on quantitative characteristics of Polianthes tuberose L. (cv. Goldorosht Mahallat) was investigated. This research was conducted in a factorial experiment based on block design with 3 replications. 40 and 54 days after planting, the flowers were sprayed with various concentrations of Gibberellic acid (GA3) and Benzyladenine (BA) (0, 50, and 100 ppm). The results showed that, flowering stem length and leaves length were greatest with GA3 at 100 ppm while BA no increase these traits compared to the control. GA3 resulted in earlier flowering compared to the control. BA and GA3 decreased number of floret. Greatest diameter of floret and vase life of cut flower was BA at 50 and 100 ppm, respectively.
