We studied the relative role of inflorescence traits, flowering synchrony, and pollination context for infructescence and fruit initiation in two Spanish populations of Arum italicum, a species in which inflorescences are the pollination unit. In this species, a specialized inflorescence organ, the appendix, is important for pollinator attraction. However, the short floral longevity and the pro...

Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...

Maintenance of indeterminacy is fundamental to the generation of plant architecture and a central component of the plant life strategy. Indeterminacy in plants is a characteristic of shoot and root meristems, which must balance maintenance of indeterminacy with organogenesis. The Petunia hybrida HAIRY MERISTEM (HAM) gene, a member of the GRAS family of transcriptional regulators, promotes shoot...

The flower-like reproductive structure of Euphorbia s.l. (Euphorbiaceae) is widely believed to have evolved from an inflorescence, and is therefore interpreted as a special type of pseudanthium, termed a cyathium. However, fuzzy morphological boundaries between the inflorescence, individual flowers, and organs have fuelled the suggestion that the cyathium does not merely superficially resemble ...

One of the most remarkable manifestations of plant evolution is the diversity for floral branching systems. These "inflorescences" arise from stem cell populations in shoot meristems that mature gradually to reproductive states in response to environmental and endogenous signals. The morphology of the shoot meristem maturation process is conserved across distantly related plants, raising the qu...

Meloidogyne spp. are recognized worldwide as causing root galls on a wide range of plants. They have also been reported to cause galls on above-ground parts of 26 plant species in 22 genera, either under natural field conditions or after artificial inoculation (2,3,5,8,10-13). We observed galls containing root-knot nematodes on inflorescences and leaves of Palisota barteri Hook. f. in a Florida...

.in order to investigate the effects of plant growth promoting rhizobacteria and nitrogen fertilizer on morphological traits of german chamomile (matricaria chamomilla l.), a field experiment was carried out as factorial based on randomized complete block design with three replications in research farm of the faculty of agriculture, university of tabriz, iran, during 2007-2008. factors were ino...

Thotteasivarajaniivar.anamalaianavar.nov., discovered from theAnamalaihills of Western Ghats, India is described and illustrated. The woody habit,comparatively less pubescent inflorescence flowers, glabrous stem, petiole fruits,highly reducedstaminodes, prominent bracts bracteolesetc. are some the characteristics that delimit thisvariety species proper.

Flowering plant density can increase number of visits and fruit set in multi-flowering plants, however this aspect has not been studied on few flower species. We studied the effects of individual floral display and plant density on the fruit production of the epiphytic, moth-pollinated orchid, Ryncholaelia glauca, in an oak forest of Chavarrillo, Veracruz, Mexico. Species is non-autogamous, and...

ten gerbera cultivars (‘labinel’, ‘lilla’, ‘alp’, ‘alberino’, ‘bonnie’, ‘avemaria’, ‘mammut’, ‘lexus’, ‘‘terramixa ’ & ‘sarolta’) were evaluated for their growth, yield and quality characteristics under protected conditions during 2011. among the cultivars studied, there were highly significant variations observed for growth, yield and quality parameters. longest stalk length (60.3 cm) was ...
