The influence of gibberellic acid (GA3) and water regime was evaluated in the flowering induction and quality of two orchid hybrids belonging to the genera Cattleya (C.) and Brassocattleya (Bc.). The experiment was carried out in the Biotechnology and Orchid Culture Sector of Shunji Nishimura Technology Foundation, Pompéia, São Paulo State, Brazil. Five GA3 concentrations (0, 125, 250, 500 and 1,000 mg L-1) were tested through four consecutive leaf applications in adult plants that had already flowered at least once, besides two water conditions (one and four irrigations per week). Applications were performed in October and November for Bc. Marcella Koss and in January and February for C. Irene Holguin. Flowering could not be induced in the latter by gibberellic acid. In Bc. Marcella Koss, the application of 250 mg L-1 GA3 combined with decreased irrigation frequency induced flowering in around 83% plants. By using the same GA3 concentration but frequent irrigation, only 17% plants were induced to flower. The number and size of flowers increased after application of higher GA3 concentrations. This work allowed developing a commercial technique with the use of gibberellic acid (GA3) to induce flowering in Bc. Marcella Koss hybrid orchid.

Rain-induced cracking of sweet cherries (Prunus avium L.) is a major problem in many cherry growing regions throughout the world. One method to reduce cracking is to grow cracking resistant cultivars; however, no completely effective control measures are currently available to eliminate this problem. Studies conducted in New Zealand to test the ameliorating properties of gibberellic acid sprays to reduce cracking were examined. The results revealed that repeated or singular foliar applications at 10 or 40 mg L-1 gibberellic acid (GA3), respectively, increased both fruit cracking, and fruit firmness, but delayed fruit colour development.

Aims: To determine the effect of post shooting spray and bunch bagging on per day productivity and quality of banana (Musa paradisiaca L.)” Study Design: Completely Randomized Design (Factorial) with three repetitions. Place and Duration of Study: Experiment was carried out at the Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture,  AAU, Anand during the year 2017-18 and 2018-19 Methodology: The experiment comprises of twenty four treatment combinations involving two varieties viz. Grand Naine and William with six levels of post shooting sprays namely; control, humic acid 2 %, 2, 4-D 30 mg/l, gibberellic acid (GA3) 100 mg/l, CPPU 4 mg/l and sulphate of potash (SOP) 2 % with two bunch bagging viz., non- woven material bag covering and blue colour polyethylene sleeve (6 % perforated) bag covering. Post shooting sprays were given twice i.e. 1st spray after complete opening of inflorescence and 2nd spray after 30 days of first spray with covering the bunch immediately after second spray. Results: The results indicated that the Grand Naine variety recorded significantly minimum harvest days, maturity days. Whereas, William variety was recorded significantly shelf life and fruit appearances. In case of per day productivity is concerned, both the varieties were equally important. The post shooting spray of GA3 100 mg/l recorded significantly improves per day productivity and fruit appearances. Whereas, post shooting spray of SOP 2 % recorded minimum harvest day and maturity days. While, post shooting sprays of CPPU 4 mg/l showed significantly maximum shelf life. The non-woven material bag covering was significantly better among all quantitative and qualitative parameters as compared to blue colour polyethylene sleeve bag covering. While, post shooting spray of CPPU 4 mg/l with non-woven material bag covering showed significantly expand the shelf life of fruit. Conclusion: Grand Naine variety recorded significantly minimum harvest and maturity days. Whereas, William variety was recorded significantly shelf life and fruit appearances. The post shooting spray of GA3 100 mg/l was improved per day productivity and fruit appearances. Whereas, post shooting sprays of CPPU 4 mg/l showed significantly enhancing the shelf life. The non-woven material bag covering on banana bunches was found significantly better among all quantitative and qualitative parameters.
