Abstract:
An experiment was carried out to study the “Effect of Different Chemicals on Vase Life of Gladiolus Varieties (Gladiolus hybridus Hort.)” during December,2016 to February, 2017 at the laboratory of Department of Floriculture and Landscaping, College of Horticulture & Forestry, Jhalarapatan City, Jhalawar (AU, Kota). The experiment consisted of 56 treatment combinations in which seven varieties (African Star, Snow Princess, Hunting Song, Legend, Darshan, Pusa Srijana, Pusa Kiran), two chemicals (SNP, AgNO₃) and their three levels, Sucrose 5% and distilled water was laid out in Completely Randomized Design (CRD) with three replications. Treatment with AgNO₃ 300 ppm in combination with 5% sucrose was observed to be best in terms of vase life and quality parameters of flowers i.e. solution uptake, number of basal florets open at a time, numbers of florets open at senescence of basal florets, in all the varieties except, ‘Darshan’, where SNP 100 ppm in combination with 5% sucrose can also be used as it showed better performance for most of the parameters. Among the varieties, cv. ‘Hunting Song’ can be used as it showed best performance for all the parameters than other varieties used for investigation. Based on the B: C ratio, chemical SNP was found better for increasing the vase life of gladiolus as compared to AgNO₃.
