Role of Ethylene and 1-MCP in Flower Development and Petal Abscission in Zonal Geraniums
Geraniums are sensitive to ethylene during shipping and respond by abscising their petals. Treatment of stock plants with ethylene (ethephon) in order to increase cutting yield resulted in earlier flowering in Pelargonium × hortorum ‘Kim’ and ‘Veronica’, but did not result in increased susceptibility to petal abscission following exposure to 1.0 μL·L–1 ethylene. Treatment of ‘Kim’, ‘Veronica’, ...
متن کاملPistillate Flower Abscission - 1990
Evaluation of the pistillate flower abscission (PFA) potential of UC-67-13 and UC-67-11 was continued at two sites. At a high PFA site UC-67-13 PFA was only moderately lower than Serr for the third year. UC-67-11 demonstrated low PFA potential for a seconq year at this site. Higher PFA potential of UC-67-13 than UC-67 -11 was also found at a second site for a second year. No further evaluation ...
متن کاملPistillate Flower Abscission (pfa)
PFA was not different with shaded vs. exposed limbs of the same trees nor between shaded interior trees and outside ones with high light exposure. Tehama trees expressed lower PFA than adjacent Serre PFA of Tehama was also low at a site where Serr trees (removed 1982) had very high drop the previous three years. Fruitfulness of all monitored limbs in 1982 ranged from 6 to 97% and the earlier co...
متن کاملEffect of Gibberellic Acid Pulsing and Sucrose Continuous Treatment on Some Qualitative Characteristics of Cut Rose Flower cv. Velvet
The aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. Velvet. Hence, an experiment involving the pulsing treatment with gibberllic acid (GA3) at 0, 20, 40 and 60 mg L-1, for 2...
متن کاملEthylene and flower longevity in Alstroemeria: relationship between tepal senescence, abscission and ethylene biosynthesis.
Senescence of floral organs is broadly divided into two groups: those that exhibit sensitivity to exogenous ethylene and those that do not. Endogenous ethylene production from the former group is via a well-characterized biochemical pathway and is either due to developmental or pollination-induced senescence. Many flowers from the order Liliales are characterized as ethylene-insensitive since t...
