Effect of ethanol and methanol on some qualitative, quantitative traits and carnation cut flowers( Dianthus caryophyllus ) vase life

For study the effect of ethanol and methanol on post harvest quality and vase life of carnation cut flowers( Di a n t h u s c a r y o p h yll u s ), experiment into a completely randomized design with 8 treatments, 3 replicates and each replication with 5 branches of flowers and a total of 120 branches of cluster were done. Treatments included ethanol and methanol with 3 levels 2, 4 and 6 % with, 3% sucros done. 3% sucros and distilled water as control. The evaluated traits included relative fersh weight, dry weight, solution uptake, cell membrane stability index, anthocyanin of petals, total chlorophyll of leaf and vase life of cut flowers. The results showed that the treatment with ethanol 4% with 3% sucrose had the most effect on the evaluation of traits such as relative fresh weight, dry weight, solution uptake, stability index of cell membrane and vase life of cut flowers and treatment with methanol 4% with 3% sucrose had the greatest effect on the improvement of traits such as anthocyanin of petals and total chlorophyll of leaf. The highest vase life was 9.7 days in ethanol 4% with 3% sucrose and lowest in 5.2 days in control treatment. The statistical results showed that the majority of traits had significant difference at 1% level and anthocyanin of petals and total chlorophyll of leaf had significant difference at 5% level. Also, the correlation between all traits was statistically significant at 1% and 5%, respectively. Therefore be argued that post-harvest application of ethanol and methanol improved the vase life and morphological and physiological characteristics of carnation cut flowers compared to control and sucrose treatment.
