Description: Annual herb, 30-150 cm high, slightly aromatic stems erect, robust, much branching, cylindrical, furrowed, densely leafy. Leaves alternate , with special odor, with broad leaf sheath, lower leaves pinnate, with narrowlyliner lobes; middle and upper leaves 2-3 pinnate, with filiform lobes. Inflorescence dense umbel with numerous rays( to 120 or more) slender in flower, thickened and...

to evaluate the effect of shoot girdling, fruit thinning, urea, sucrose and zinc on inflorescence bud retention in pistachio, an experiment comprised of 12 treatments including girdling, fruit thinning, application of urea (0.5%), and sucrose (3 and 5%) and their combination of the first two with urea plus zinc sulfate (0.05 and 0.1% of pure zinc) as well as a combination of the two with urea, ...

Vitis vinifera glycosyl hydrolase family 17 (VvGHF17) is a grape apoplasmic β-1,3-glucanase, which belongs to glycosyl hydrolase family 17 in grapevines. β-1,3-glucanase is not only involved in plant defense response but also has various physiological functions in plants. Although VvGHF17 expression is negatively related to the length of inflorescence in grapevines, the physiological functions ...

The relationship between fruit development and the proliferative capacities of inflorescence meristems has been examined in Arabidopsis thaliana. In the wild-type Landsberg erecta (Ler) line, flower production ceases coordinately on all inflorescence branches by a process we have designated global proliferative arrest (GPA). Morphological studies indicate that GPA involves a cessation of prolif...

Ferulago macedonica Micevski & E. Mayer (Apiaceae), an endemic species from Macedonia, was evaluated for its essential oil composition and biological activity for the first time. The essential oil composition from inflorescence and aerial parts, analyzed by gas chromatography and gas chromatography–mass spectrometry (GC and GC-MS), indicated α-pinene (43.10% and 22.78%) and sabinene (26.73% and...

Other than studies on sex-labile Arisaema species, studies of gender patterns in Araceae are scarce. The modification of phenotypic and functional gender was investigated in three populations of the monoecious Arum italicum Miller. The probability of reproduction and the number of inflorescences produced increased with plant size, and flower number (total, male, staminodes, female, pistillodes)...

In Arabidopsis floral meristems are specified on the periphery of the inflorescence meristem by the combined activities of the FLOWERING LOCUS T (FT)-FD complex and the flower meristem identity gene LEAFY. The floral specification activity of FT is dependent upon two related BELL1-like homeobox (BLH) genes PENNYWISE (PNY) and POUND-FOOLISH (PNF) which are required for floral evocation. PNY and ...

Epidendrum radicans is a food deceptive Batesian mimic of its sympatric model species Asclepias curassavica and Lantana camara. Theoretically, food deceptive orchids should be rare with small inflorescences (Johnson et al. 1993; Weins 1978) yet in San Luis, Costa Rica E. radicans grows in large monotypic stands with individuals sporting up to 12 open flowers per inflorescence. E. radicans might...

Variation in inflorescence development patterns is a central factor in the evolutionary ecology of plants. The genetic architectures of 13 traits associated with inflorescence developmental timing, architecture, rosette morphology, and fitness were investigated in Arabidopsis thaliana, a model plant system. There is substantial naturally occurring genetic variation for inflorescence development...

abstract tuberose is one of the most important cut flowers in iran and the world. in this experiment, effect of microelements fe, zn, cu and mn on inflorescence length, inflorescence bunch length, number and diameter of floret, diameter of inflorescence bunch and vase life of tuberose flowers were studied. this study was based on four separate completely randomized experimental design with four...
