บทคัดย่อ

The effects of a combination of trehalose and sodium dichloroisocyanurate (DICA) on reducing the growth of microorganisms in the vase solution and improving the quality of 'Grand Gala' cut rose flowers was investigated. Flower stems were held in distilled water (control; DW), Floralifeฎ, 2% trehalose (Tre) and 2% trehalose + 50 mg L-1 DICA (Tre + DICA) for 7 d in an observation room (21ฑ2ฐC, 70-80% RH, cool-white fluorescence lights for 12 h d-1). The results showed that treatment of Tre + DICA was the most effective for inhibiting microbial growth, followed by Floralifeฎ solution which delayed the increase in microbial content in the vase solution. In contrast, flowers held in DW and Tre had the greatest number of microorganisms in the vase solution. This was related to the microbial content observed in the xylem on days 0 and 6 by scanning electron microscopy (SEM). Microbial growth was almost undetectable in the Tre + DICA treatment while 'Grand Gala' flowers held in Tre and the control had significant microbial content in the xylem in day 6. Additionally, cut rose flowers held in the Floralifeฎ solution and Tre + DICA increased the water uptake and had the longest vase life of 7.8 and 7.6 days, respectively, while, the control flowers showed the shortest vase life of 4.9 days. Treatments of Tre + DICA and Tre had significantly higher total sugar content in petals than others. However, there were no significant differences in fresh weight and ethylene production among all treatments. ฉ 2016, International Society for Horticultural Science. All rights reserved.
