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...

rose (rosa hybrida l.) is one of the mostly cultivated cut flowers in iran and around the world. the study was carried out to increase the vase life and quality of cut rose ‘grand prix` and ‘avallanche` by using various floral preservative solutions. floral preservative solutions were agno3, 8-hqs, nano silver and distilled water. treatments were compared with tap water as control. the experime...

Preharvest conditions, including photoperiod and irrigation regime, affect the keeping quality of long stem roses (Rosa x hybrida). Rose plants cultivar ‘Charming Black’ were subjected to four different treatments investigate how nocturnal supplemental lighting regimes influence post-harvest performance. Vase life, ornamental quality, water balance, petal color, vacuolar pH, soluble sugar conte...

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...

The effects of savory, caraway, and rose extracts and 8-HQS were studied on the vase life of Alstroemeria cut flowers. The plant extracts at three levels (10, 20, and 40 %), 8-HQS at three levels (100, 200, and 300 mg l-1), and control (distilled water) with 3 % sucrose were continuously applied on the basis of a Completely Randomized Design with three replications. It was f...
