tuberose cut flower is considered one of the most important cut flowers from the viewpoint of production and export. the failure of developing buds into open ones and the abscission of floret are two of the common problems in the postharvest of tuberose cut flower that diminishes its longevity and therefore its market quality. this research was conducted to investigate the effect of 2,4-d sucro...

the effects of postharvest application of cobalt chloride were investigated on vase life of rose stood individually in vials and the other ones placing daffodil flowers in a vase with a rose flower.  therefore, roses were treated with: cocl 2 (100, 200, 300 mg l -1 , respectively) or distilled water (control). the results showed that the decreased vase life of rose flowers, after daffodil was p...

Gerbera one of 10 important cut flowers in the world and Iran. One of the most problems is low-life after harvest and neck bending. Producers want to increase longevity of these flowers with using chemical solutions. With the aim of achieving the best chemical treatments to increase flower vase life gerbera Goodtimming, nano silver (5 mg l-1), humic acid (50 mg l-1), gibberellic acid (2.5 mg l-...

Flowers are susceptible to many pests and diseases. Therefore, they can be sprayed several times during their growth considering that no MRL are set for flowers. High levels of pesticide residues potentially expose daily the florists who handle cut flowers and possibly could endanger their health. A study was carried out to evaluate the risk for florists exposed to fungicide residues during nor...

The main postharvest disorder of cut gerbera flowers is the stem bending and break. The cause of stem bending is not completely clear. Although the genetic background seems to play the major role, some plant hormones such as ethylene and cytokinins may enhance or reduce the incidence of stem break during postharvest life. The choice of withstand genotypes seems to be a good strategy. In fact, s...

Farmers in developing countries like Pakistan do not make the best use of allpotential resources; therefore, they inefficient decisions their agricultural activities. Primarilythis study aims at estimating efficiency Statice (cut-flower) production and also investigating somesocioeconomic factors responsible for inefficiency. A survey with a sample 70 farmers engaged inthe cultivation cut flowe...

This study was conducted to evaluate the effect of preservative solutions on vase life, number of bacteria in the end of stem and in vase solution of cut gerbera 'Double Dutch' and 'Red Explotion'. Cut flowers were pulse-treated with nano-silver (2, 4, 6, 8 or 10 mg L-1) and thymol (12.5, 25, 50, 75 or 100 mg L-1) +5 % sucrose. Experiment was conducted in completely randomized design with 5 rep...

Senescence is an integral part of the normal developmental cycle of plants and can be traced in cell, tissue and organ level. This work was focused on the efficiency of post-harvest treatment with the free polyamine spermine (Spm) to extend the vase life of cut rose flowers as an anti-senescence compound. Spm treatment was applied at the rates of 0, 1, 2 and 4 mM. Some morphological, biochemica...
