to evaluate the effect of chemical and bio-fertilizer on nitrogen, phosphorus and potash concentration, biochemical traits and calyxes yield of roselle, an experiment was conducted in the split plot based on randomized coplete block design with three replications, at the research station in zabol university, during 2013 and 2014. the main plot consisted of three levels: phosphorus, nitrogen and...

This work was carried out during the two seasons of 2008 and 2009 aiming to study the effect of different levels of cattle manure and biofertilizers (phosphorein and/or nitrobein) as well as their interactions treatments on the growth, sepals, seed yields and some chemical constituents of roselle plants. The obtained results show that all levels of cattle manure and inoculated biofertilizers an...

Epimedium L. (Berberidaceae, Ranales), a perennial traditional Chinese medicinal herb, has become a new popular landscape plant for ground cover and pot culture in many countries based on its excellent ornamental characteristics and, distinctive and diverse floral morphology. However, little is known about the molecular genetics of flower development in Epimedium sagittatum. Here, we describe t...

A study was undertaken to compare the anatomy of the laminar floral parts with that of the spathes and leaves of Commelina erecta L. Each flower has two types of petals and two types of sepals. In contrast to the other organs, the petals have a completely open venation system whose vein endings consist solely of modified bundle-sheath cells. Bundle sheaths of leaves and spathes, but not the flo...

Calolisianthus speciosus, an endemic species of cerrado and campos rupestres in Brazil, bears colleters both the leaf base sepal. These (leaf sepal) were anatomically compared to identify differences their structure secretion mechanism. Samples sepals leaves different development stages collected processed according standard methodologies for anatomical ultrastructural studies. Sepal similar, b...

We investigated whether the Arabidopsis flower evolved protective measures to increase reproductive success. Firstly, analyses of available transcriptome data show that the most highly expressed transcripts in the closed sepal (stage 12) are enriched in genes with roles in responses to chemical stimuli and cellular metabolic processes. At stage 15, there is enrichment in transcripts with a role...

The mitogen-activated protein kinase (MAPK) cascade signaling system has been relatively conserved throughout the evolution of eukaryotes and is involved in regulation growth development metabolism. In this study, dwarf tomato plants were used as research material. First, tissue-specific expression SlMAPK6 was measured wild-type by quantitative RT-PCR. results showed that highly expressed tissu...

A newly recovered twig with attached leaves and flowers from the Eocene Green River Formation of Utah provides the basis for recognizing a new, extinct genus of Salicaceae sensu lato (s.l.). Pseudosalix handleyi gen. et sp. nov. has alternate lanceolate leaves with pinnate, semicraspedodromous venation and a serrate margin with glandular teeth. The inflorescence is terminal on the twig and is u...

Background and aims – Two new species of Vellozia (Velloziaceae) are here described illustrated, albohexandra V. mellosilvae . These morphologically similar to armata , luteola inselbergae probably belonging the same informal group. Material methods Morphological anatomical descriptions were based on herbarium specimens in situ observations. Standard taxonomy plant anatomy practices applied. Ke...
