the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...

The effects of salicylic acid (SA) and Putrescine (Put), on cut Gladioluswas studied. SA (0, 150, 300 and 450 mg l-1) and Put (0, 100, 200 and 300 mg l-1), their combinations were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design on 192 Gladioluscut flowers in horticulture laboratory of agriculture faculty of...

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...

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. ...

Varieties of the economically important ornamental species chrysanthemum have been bred to fit a number of market niches, but the genetic basis and evolutionary relationships among various cultivated types are poorly understood. Here, a DNA marker-based analysis of 199 chrysanthemum entries representing each of the five cultivated types is presented. A set of >90,000 single nucleotide polymorph...

The experiment was carried out to investigate the effect of different concentrations of salicylic acid (SA), malic acid ( MA), citric acid (CA) and sucrose (Suc) on keeping quality and vase life of Chrysanthemum cut flowers. In this study three levels of malic acid (0, 100 and 150 mg l ) and salicylic acid (0, 1.5 and 3 mM) and two levels of sucrose (0 and 3% w/v) and of citric acid (0 and 150 ...

the present study has assessed the effect of cola in increasing flower longevity of flower and delaying aging of cut alstroemeria ‘balance’. distilled water was used as control. traits of flower diameter, solution absorption ,anthocyanins, total soluble solids and chlorophyll were measured at 3 times and vase life was measured daily. based on the results, flower diameter, anthocyanins and chlor...
