qajar period is recognized as a time of significant changes in persian arts. perhaps the most obvious change was the influence of european arts especially on architecture, painting as well as pottery. however after safavid period as to several inside and outside factors, amongst them vast importation of porcelain wares, iran was faced with stagnation of pottery’s art but this doesn’t mean the a...

Corolla chirality, the pinwheel arrangement of petals within a flower, is found throughout the core eudicots. In 15 families, different chiral type flowers (i.e., right or left rotated corolla) exist on the same plant, and this condition is referred to as unfixed/enantiomorphic corolla chirality. There are no investigations on the significance of unfixed floral chirality on directed pollen move...

BACKGROUND AND AIMS The genus Gesneria diversified in the Greater Antilles giving rise to various floral designs corresponding to different pollination syndromes. The goal of this study was to characterize the pollination and breeding systems of five Puerto Rican Gesneria species. METHODS The study was conducted in Arecibo and El Yunke National Forest, Puerto Rico, between 2003 and 2007. Flor...

iran is a large country with a vast variety of tribes and ethnic groups. these various tribes are unified with a national language and culture while using their own local languages and enriching ethnic art forms. among iranian ethnic groups, the turkmen are remarkable for their art of carpet weaving which has a unique structure compared to other designs and textures. the charming motifs on turk...

There is a great need to implement low-cost and user-friendly methods for further propagation of biogas technology in India. Environment unfriendly disposal of floral waste causes serious environmental pollution. Literature shows a limited research work regarding the anaerobic digestion of floral waste for biogas generation.  The present experimental work aims to propagate floral waste as a sus...

Stigma-height dimorphism is a sexual polymorphism in which plant populations are composed of two floral morphs that differ significantly in style length but not anther position. The morphs exhibit approach and reverse herkogamy, floral designs that in most species typically occur as monomorphic conditions. We investigated the floral biology of stigma-height dimorphism in the Mediterranean geoph...

In flowering plants, the founder cells from which reproductive organs form reside in structures called floral meristems. Recent molecular genetic studies have revealed that the specification of floral meristems is tightly controlled by regulatory networks that underpin several coordinated programmes, from the integration of flowering signals to floral organ formation. A notable feature of certa...
