in this research the effect of potrecine, spermine and spermidine on the postharvest life of cut red carnation (corsa) and some physiological trait was investigated in horticultural lab of azad university. therefore, an experiment based on completely randomized block design with tree levels of putrescine (1, 2 and 3) mm and spermidine (0.5, 1 and 2) and spermine (1, 2 and 3) mm with 3 replicati...

X-ray irradiation with convergent chemicals such as nano-silver particles or sodium dichloroisocyanurate (NaDCC) has been used to control leaf blight on cut lilies. The oriental hybrid lily cultivars Siberia, Le Reve, and Sorbonne were irradiated five times by 200 Gy of X-rays in 2014. In 2015, Siberia and Sorbonne were irradiated three times by 150 Gy of X-rays. After artificial infection with...

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 islamic azad universi...

Native to South America, Alstroemeria flowers are known for their colourful tepals, and Alstroemeria hybrids are an important cut flower. However, in common with many commercial cut flowers, virtually all the commercial Alstroemeria hybrids are not scented. The cultivar 'Sweet Laura' is one of very few scented commercial Alstroemeria hybrids. Characterization of the volatile emission profile of...

Bioreduction of silver nanoparticles (AgNPs) from silver ions (Ag) using water extract of Thai basil leaf was successfully carried out. The basil leaf extract provided a reducing agent and stabilizing agent for a synthesis of metal nanoparticles. Silver nanoparticles received from cut and uncut basil leaf was compared. The resulting silver nanoparticles are characterized by UV-Vis spectroscopy....

the aim of this paper was to assess the effect of catechol (ch), as a peroxidase inhibitor, and 8-hydroxyquinoline citrate (hqc), as a bacterial inhibitor, on keeping the quality of gerbera jamesonii cv. hongyan cut flowers, known to be limited by vascular occlusion. blockage in the stem xylem vessels of cut gerbera was studied using light and scanning electron microscope. the results showed th...

the vase life of cut flowers and foliage is often shortened by vascular occlusions that constrict vase solution supply. reduction in stem conductivity is typically caused by blockage of cut stem ends and xylem conduits by microbes, physiological plugging, and disruption of water columns in xylem vessels by cavitations and air emboli. cut flower and foliage longevity can be greatly affected by t...

This research was conducted to investigate the effects of peppermint (Mentha piperita) essence treatment (2000 mg L-1) and cola soft drink treatment separately and in combination with each other on the vase life and some physiological characteristics of gerbera (Gerbera jamesonii) cut flowers with factorial arrangement in a completely randomized design with 3 replications. Distilled water used ...

in this study, effect of different concentration of ascorbic acid (asa, 0, 2, 4 and 6 mm) on delaying senescence in cut rose flowers cv. royall class was investigated based on factorial design. the results showed that the greatest delay in senescence was obtained with 4 mm asa as compared to control (distilled water). therefore, fresh weight and diameter of flowers treated with 4 mm asa was mor...
