Improving the Quality of Jasminum grandiflorum Flower Buds by Delaying of Senescence

An experiment was conducted to study the flower senescence physiology in Jasminum grandiflorum . Hence, the senescence is a highly coordinated complex and genetically programmed natural process that mainly regulated by phytohormones. The experiment was conducted by following factorial completely randomized design with three replications. The harvested jasmine flowers were treated with different anti-senescence chemicals viz., Silver nanoparticle (20ppm), Boric acid (4%), sucrose (4%), NAA (100 ppm), BA (500 ppm), α-AIB (20µM) and packed in 200 gauge with no ventilation then stored in cold storage and ambient storage condition. Different physiological and biochemical parameters were taken up at three different stages like bud stage, open stage and senescence stage. Among these treatments silver nanoparticles (20 ppm) shows positive significant difference in moisture content, membrane stability index, protein content, phenol content and improve the flower bud quality over the control.
