Carnation is an important traded crop in many countries. Postharvest senescence is a major limitation to the marketing of many species of cut flowers and considerable effort has been devoted to developing postharvest treatments to extend the marketing period. The split-plot experiment was executed based on two factors randomized complete block design with three replications to examine the effec...

Ethylene plays an important role in wide-ranging aspects of plant growth and development, includingfruit ripening, leaf and flower senescence. In this study, the expression patterns of two genes involved in theethylene signal transduction pathway (RhCTR1 and RhCTR2) were investigated during the flower openingstages in two Rosa hybrida cultivars, ‘Black magic’ and ‘Maroussia’, ...

Abstract Flower sepals are critical for flower development and vary greatly in life span depending on their function post-pollination. Very little is known about what controls sepal longevity. Using a senescence mutant screen, we identified two Arabidopsis mutants with delayed directly connecting strigolactones regulation novel floral context that hitherto has not been explored. The mutations w...

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...

Selected physiological and biochemical parameters were monitored at the vegetative and reproductive growth stages in potted Bougainvillea plants treated with five different concentrations of TRIA. Advanced flowering, flower bud number, and blooming rate increased significantly with 0.5 and 1.0 mg/L TRIA treatments. Similarly, photosynthetic rate, pigment content, quantum yield, and stomatal con...

Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in post-harvest. The leaf area measurement fundamental plants because leaves are directly related several processes such as transpiration, radiation interception CO2 fixation that enable plant grow. objective work was determine an allometric equation for estimating lisianthus from linear di...

Abstract Flower senescence is commonly enhanced by the endogenous hormone ethylene and suppressed gibberellins (GAs) in plants. However, detailed mechanisms for antagonism of these hormones during flower remain elusive. In this study, we characterized one up-regulated gene PhOBF1, belonging to basic leucine zipper transcription factor family, senescing petals petunia (Petunia hybrida). Exogenou...
