Cardinal, under room conditions with normal day light and natural ventilation. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. A combined solution of Silver thiosulfate (STS) with 0ppm (control), 15ppm, 20ppm, 25ppm and Sucrose 0% (control), 2.5%, 5% and 7.5% concentrations were applied to the rose cut flowers. Data collected on daily basis revealed that both STS and sucrose generally showed significant results at all concentrations. Furthermore, a chemical combination of 25ppm STS with 7.5% sucrose gave the promising results for all the parameters. Maximum flower longevity (10.12 days), flower diameter (7.01 cm), flower dry weight (4.38 g) and delayed flower opening period (6.87 days) were recorded for flowers placed in solution combination of 25ppm STS and 7.5% sucrose. Flower fresh weight was signifi...

Results of the current study revealed that chloroform, ethyl acetate and n-hexane extracts exhibited notable antibacterial action against the tested gram positive bacteria, i.e., Bacillus subtilis and Staphylococcus aureus. Whereas the sensitivity of gram negative bacteria (Escherichia coli) to antibacterial action of plant extracts was considerably trivial. Moreover, chloroform extract was superior to ethyl acetate and n-hexane extracts in terms of antibacterial activity. By taking the overall results it was concluded that Sorghum halepense is a potential source of natural antibacterial constituents. Additional research should be undertaken to elaborate the mechanism of action and antimicrobial spectrum of Sorghum halepense. Furthermore, screening of plant extracts for antibacterial efficacy against resistant strains of Staphylococcus aureus, for instance methicillin-resistant Staphylococcus aureus (MRSA) is also recommended.

Flower fresh weight was significantly increased (12.42 g) in solution having 20ppm STS and 7.5% sucrose. Likewise, solution combination of 25ppm STS and 7.5% sucrose results in a 15% less percent petal drop as compared to control (36.75%). Moreover, STS and sucrose as individual treatments also showed significant effects in some of the parameters. A significantly minimum flower percent fading (11.25%), maximum flower longevity (8.99 days), majorly delayed flower opening period (5.87 days) was recorded for flowers placed in 25ppm STS solution. In general, 7.5 % sucrose and 25ppm STS is the best considered solution combination to be used for long preserved vase life of cut rose flowers.
