Increasing quality and vase life of cut flowers play vital role in flower production industry. . Lisianthus (Eustoma grandiflora cv. Echo) has short vase life and it has been revealed that ethylene directly affect the initiation and process of senescence of petals. In this study, the effects of Silver and silicon nanoparticles with four concentrations of 0, 10, 20 and 40 mg L-1 with 4% sucrose...

the effect of some treatments including preserving solution (20g l-1 sucrose plus 200 ppm 8-hqs), ba and tdz (pulse or spray) with preserving solution were evaluated on senescence parameters and vase life of rose cut flowers cv. red gant. preserving solution, applying 25 mm ba with preserving solution increased solution absorbance, and prevented the cut flowers from getting decreased in relativ...

The anti-senescence biogenic polyamines (PAs) putrescine (Put), spermidine (Spd) and spermine (Spm) are involved in plant growth processes and responses to stress. The physiological mechanism of exogenous Put to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM Put and then...

the effect of plant growth regulator short time treatments ( ga3 and tdz) on the increase of vase life and qualitative traits of alstroemeria cultivars ‘odessa’ and ‘sacramento’ were investigated. cut flowers were treated with 24h pulse treatments which included different concentrations of ga3 and tdz. cut flowers were later held in preservative solution (sucrose 2% +nanosid 2ppm) and then thei...

this experiment was conducted in national institute of ornamental plants for extending vase life of anturium andranum cv. climax cut flowers. experiment was done based on completely randomized design (crd) with three replications and three cut flowers per replicate. treatments included volk oil emulsion wax coating (10, 20 and 30 percent), thyme oil (100, 150 and 250 ppm), salicylic acid (200, ...

salicylic acid (sa) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. the physiological mechanism of exogenous sa to affect the senescence of cut lisianthus flowers during vase life was investigated. fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mm sa and then held at 25◦c up to 12 days. ...
