In this research, the effects of thidiazuron pulse treatment and salicylic acid were examined to improve vase life and maintain the quality of Alstroemeria ҅Modena҆ cut flowers. The experiment was done in a factorial experiment based on RCD with 16 treatments, 3 replications and 48 plots. The flowers were placed in different concentrations of thidiazuron (0, 10, 20, and 50 μM) and salicylic acid ...

To evaluate the effect of nanosilver (5, 10 and 20 mg l-1), hydrogen peroxide (200, 400 and 600 µM) and Nanosil (200, 400 and 600 µM) as antimicrobial compounds in vase solution of cut rose cv. ‘Grand Press Angela’ flowers, an experiment with 10 treatments and 3 replications was conducted in a completely randomized design. Cut rose flowers were continuously treated with these compounds. The res...

The most popular fragrant cut rose cultivar in Japan is ‘Yves Piaget’, but its petals often become malformed after harvest. These flowers, referred to as “incurved flowers”, are characterized by curving toward the adaxial side which prevents normal flowering and significantly decreases flower quality. It has been reported that jasmonic acid (JA) affects petal growth, could suppress emergence of...

In recent systematic treatments of the Cyperaceae, spikelets of all but the most primitive tribes have been considered to be indeterminate, whereas historically the number of flowers, floral sex and distribution of sexes in spikelets have been important characters in suprageneric classifications. However, descriptions of these spikelet characteristics for sawgrass, Cladium jamaicense Crantz, va...

Our understanding of how floral visitors integrate visual and olfactory cues when seeking food, and how background complexity affects flower detection is limited. Here, we aimed to understand the use of visual and olfactory information for bumblebees (Bombus terrestris terrestris L.) when seeking flowers in a visually complex background. To explore this issue, we first evaluated the effect of f...

the effect of different storage temperatures on senescence and postharvest performance in cut scapes of three iris species (iris germanica, iris reticulata and iris kashmiriana) was studied with the aim to develop a cost-effective storage protocol so as to bring out the transportation of these cut flowers. the scapes were subjected to two different storage treatments-dry storage and wet storage...

Short vase life and post-harvest losses of cut flowers are major threat to floriculture industry. There different preservative solutions that have been used extend the flowers. Hence, this study was executed at Floriculture laboratory Ayub Agricultural Research Institute, Faisalabad during 2018-2020 explore efficacy on quality roses. were 6 treatments viz, (T1= Distilled water, T2= Silver nitra...

The effectiveness of fungistatic atmospheres for postharvest control of Botrytis cinerea Pers. infections on cut rose flowers (Rosa hybrids L.) was investigated. Storing cut ‘Sonia’, ‘Royalty’, and ‘Gold Rush’ roses at 2.5C with 10% CO2 for 5 days, followed by 2 days of cold storage in air, reduced the number of B. cinerea lesions that developed on inoculated and noninoculated flower petals by ...

Given their small size and high metabolism, nectar bats need to be able to quickly locate flowers during foraging bouts. Chiropterophilous plants depend on these bats for their reproduction, thus they also benefit if their flowers can be easily located, and we would expect that floral traits such as odor and shape have evolved to maximize detection by bats. However, relatively little is known a...

In senescing carnation (Dianthus caryophyllus L.) flowers, ethylene is produced from the gynoecium, and acts as a diffusible signal received by petals to induce the expression of 1-aminocyclopropane-1-carboxylate (ACC) synthase (DC-ACS1) and ACC oxidase (DC-ACO1) genes in the petals. This results in autocatalytic ethylene production in the petals. We investigated ethylene production in cut flow...
