In order to investigate the application effects of different levels of benzyl adenine ( BA) and 1-methylcyclopropene (1-Mcp) on some bio-chemical characteristics and vase life of rose (Rosa hybrid L. cv. Royal Bacara),an experiment was carried out as factorial based on completely randomized design with three replications during 2017. Experimental factors included BA in three levels of 0, 75, and 150 ppm, and 1-Mcp in three concentrations of 0, 1, and 2 (µlit.lit). The results showed that the interaction of BA and 1-Mcp was significant on the biochemical characteristics and the vase life of roses.The highest antioxidant rate SOD, K and vase life in the treatment of 150 ppm BAalong with 2 µlit/lit 1-Mcp was achieved. This treatment was allocated the lowest rate MDA, DT and Ec. This results indicated that BA and 1-Mcp have effect on durability of rose.In general, the result showed that application of 1 or 2 µlit/lit 1-Mcp along with150 ppm AB was improve some physiological and biochemical characteristics and vase life ofrose cut flower.

This experiment was carried out based on a completely randomized design with three replications and two factors by applying a type of bed (manure, manure plus superabsorbents nanocamposite and vermicompost plus superabsorbents nanocamposite) and irrigation period (no stress, 5-day and 10-day) in the farm. Shoot and root height, fresh and dry weight, chlorophyll content, root penetration depth, carbohydrate, chlorophyll, prolin, carotenoid and ion leakage cnotents were measured in this experiment. The results showed that the bed containing nanocomposite superabsorbent was significant on fresh weight, dry weight and root penetration depth. The effects of irrigation period were significant on fresh weight, dry weight, root penetration depth, chlorophyll b, chlorophyll, carbohydrate, electrolyte leakage and quality (NTEP). The quality was maintained in five-day irrigation period. The interaction between bed and the irrigation period was significant for proline and Chlorophyll which indicating the tolerance of five-day irrigation period in the bed containing superabsorbents nanocomposites.
