The plant hormone ethylene is involved in the regulation of a number of physiological and developmental processes and its role as a regulator of flower senescence is of particular economic importance in floriculture. The present review focuses on genetic control of flower senescence, particularly at the level of ethylene perception. Research in a number of flowering plants has indicated that fl...

in order the the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis) an experiment in split plot randomized based on complete block design with three replications in 1393 at the agricultural research station of roudehen islamic azad university done. treatments were first factor drought in four levels (control, stress at vegetative stage, stress at flowering stage...

gladiolus is one of the flowers that used on cut flower and garden plants. an experiment was conducted to study the effects of chemical treatments on the vase life of gladiolus cut flower cv. ‘rose supreme’ with ten chemical treatment using complete randomize design with 3 replications. gladiolus cut flower was harvested when the 2-3 lowest bud had start showing color then cut flower were treat...

1. Dianthin 30 and dianthin 32, two proteins isolated from the leaves of Diathus caryophyllus (carnation), were purified to homogeneity by chromatography on CM-cellulose. 2. The mol.wt. of dianthin 30 is 29 500 and that of dianthin 32 is 31 700. Both dianthins are glycoproteins containing mannose. 3. Dianthins inhibit protein synthesis in a lysate of rabbit reticulocytes, with an ID50 (concentr...

tuberose (polianthes tuberosa l.) is one of the most important bulbous ornamental crops of tropical and subtropical areas. the objective of the present study was to determine the interaction effects of salinity and irrigation intervals on growth and flowering of two important commercial cultivars (‘mahallati’ and ‘dezfuli’) of tuberose (polianthes tuberosa l.). irrigation treatments consisted o...

narcissus is one of the very popular flowers among iranians. this flower has a short life. to investigate the increasing of vase life of cut narcissus, sour orange fruit extract in concentrations of 2.5, 4, 5.5 and 7 ml l-1 and sucrose in concentrations of 3, 4, 5 and 6% were used. in addition, distilled water was used as a control treatment. in this experiment, characters of vase life and perc...

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...

Senescence and stresses have been documented to promote ethylene synthesis in ethylene-sensitive flower such as carnations. Thus the inhibition of ethylene evolution might lead to activation of other metabolic reactions. Present experiments were undertaken with cut at bud stage spray-carnation (D. caryophyllus f. spray, Hort.) flowers, cv. Regina and cv. Naslada. Tested cultivars are a new bree...
