Response of Cut Rose Flowers to Relative Humidity and Recut During Postharvest Life
Experiments were conducted to evaluate the response of different originated (the same mother plants with different growers from different cities in Ethiopia) cut rose flowers to various relative humidity (RH) and recut (recut and non-recut). Three different experiments (E1, E2 and E3) using three RH (60, 75 and 90%) and three Ethiopian growing areas (Fleur, Liki and Longonot) with 10 replicatio...
متن کاملElevated air movement enhances stomatal sensitivity to abscisic acid in leaves developed at high relative air humidity
High relative air humidity (RH ≥ 85%) during growth leads to stomata malfunctioning, resulting in water stress when plants are transferred to conditions of high evaporative demand. In this study, we hypothesized that an elevated air movement (MOV) 24 h per day, during the whole period of leaf development would increase abscisic acid concentration ([ABA]) enhancing stomatal functioning. Pot rose...
متن کاملExpression of Genes Encoding Protein Kinases During Flower Opening in Two Cut Rose Cultivars with Different Longevity
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’, ...
متن کاملThe Role of 1-methylcyclopropene (1-MCP) in Improving the Postharvest Quality of Some Cut Rose Cultivars
In order to improve the postharvest quality and the export ability of cut rose (Rosa hybrida L.) cvs. Happy Hour and Bordeaux, the effect of 1-methylcyclopropene (1-MCP) as an ethylene inhibitor, was investigated. 1-MCP was used at 0.3, 0.4, 0.5 and 0.6 g m-3 for 18 h at 8 °C to simulate the transport of flowers. 1-MCP treatment significantly prolonged the vase life and minimized the weight los...
متن کاملHigh relative air humidity influences mineral accumulation and growth in iron deficient soybean plants
Iron (Fe) deficiency chlorosis (IDC) in soybean results in severe yield losses. Cultivar selection is the most commonly used strategy to avoid IDC but there is a clear interaction between genotype and the environment; therefore, the search for quick and reliable tools to control this nutrient deficiency is essential. Several studies showed that relative humidity (RH) may influence the long dist...
