Abstract
Dianthus is an important decorative plant cultivated from long time ago. This plant is used in vase and stem-cut forms, and is economically valuable due to its production simplicity and reasonable price. The effect of benzyl adenine with concentrations of 25, 50, and 100 mg/L on Dianthus CV. “Cream Viana” cut flower was investigated in short-term treatment (48 hours) in this study. In addition, the effects of nano silver with concentrations of 2 and 4 ppm and 8- hydroxyquinol sulfate with concentration of 300 ppm plus 3% sucrose, as the continuous treatment (preservative solution) studied. The flowers were placed at the temperature of 20ºC, relative humidity of 80%, and photo-period of 14 hours provided by fluorescent light with light intensity of 15 micromole/m2×s in the upper part of the room. Life information following picking the flower were all analyzed during the measurement procedures; these parameters included relative wet weight of flower, flower diameter, soluble solids, degree of stem bending, percentage of stability index of cellular membrane, amount of Anthocyanin, and solution uptake. The results indicated short-term treatment by Benzyl adenine of 100 mg/liter concentration together with nano silver preservative solution of 4 ppm concentration plus 3% sucrose has the greatest impact on the longevity and qualitative characteristics of Dianthus flower.

Highlights
Based on a report the sucrose treatment togetherDianthus is a plant of Caryophyllaceae family with 8-hydroxyquinolin sulfate leads to prevention from regarded as one of the most important families for flower activity of ACC enzyme, as a result, reduces ethylene planting; it comprises species such as shell-like generation, and promotes post-harvest longevity in (Gypsophila), Sweet William, and Silene
In other study observed that using placed in 500 milliliters containing 400 milliliter of the benzyl adenine in the form of spray or immersion solution, and were transferred to preservative treatment delays the aging process in anthorium cut solution containing nano silver in two concentrations of 2 flowers increasing the post-harvest longevity in most and 4 ppm and 8-hydroxyquinolin sulfate of 300 ppm cases up to 1.4-3.2 times (Paull & Chantrachit, 2001). concentration plus 3% sucrose
Using benzyl adenine with concentration of 100 mg/liters as short-term preservation and preservative solution consisting of 4 ppm nano silver and 3% sucrose was recorded as the largest amount of soluble solids in comparison with the indicator treatment (Fig. 5)
Summary
Dianthus is a plant of Caryophyllaceae family with 8-hydroxyquinolin sulfate leads to prevention from regarded as one of the most important families for flower activity of ACC enzyme, as a result, reduces ethylene planting; it comprises species such as shell-like generation, and promotes post-harvest longevity in (Gypsophila), Sweet William, and Silene. Opposing flowers (Pun et al, 2005) and other investigation leaves and nodal bulge are considered as distinctive indicated that nano silver serves as an anti-microbial characteristics of dianthus family. This plant is indigenous species of Mediterranean research is intended to investigate the effects of benzyl regions, South Europe and Central Asia
