Field trials with Dizigotheeca elegantissima were conducted at the experimental farm of Faculty of Agriculture, Azad University  Jiroft  in growth seasons of 2012 year. The aim of this work was to study the effect of foliar application of gibberellic acid [GA3] and benzyladenine [BA] at 0, 50, 100 and 150 mgL-1 on the vegetative growth and Photosynthetic pigments ...

PREMISE OF THE STUDY A new infrafamilial circumscription of the Verbenaceae with eight tribes: Casselieae, Citharexyleae, Duranteae, Lantaneae, Neospartoneae, Petreeae, Priveae, and Verbeneae, has been recently proposed, on the basis of molecular phylogenetic studies. Two genera, Dipyrena and Rhaphithamnus, remain unplaced. The aim of this work is to reconstruct the evolutionary history of morp...

The establishment and maintenance of plant species in the Chaco, one of the widest continuous areas of forests in the South American with sharp climatic variations, are possibly related to biological features favoring plants with particular defenses. This study assesses the physical and chemical defenses mechanisms against herbivores of vegetative and reproductive organs. Its analyses of 12 spe...

Miconieae is the largest tribe in the Melastomataceae with over 1,850 species. The members of Miconieae display a wide range of morphological diversity, and seed morphology is no exception. Previous studies have found that seed morphological diversity is not congruent with traditional classifications, and suggest that it may reflect evolutionary relationships within Miconieae. Here we character...

BACKGROUND AND AIMS Flowering incidence in Bambusa tulda has a high socio-economic impact. The aim of the present study was to describe the species for morphological characters (vegetative and reproductive) as well as molecular markers in order to enable species identification at various stages of the life cycle. METHODS Thirty-two key morphological characters (15 culm and 17 culm-sheath) wer...

comparison and grouping of 32 grape cultivars and genotypes by using 61 traits including; 5 phenological and vegetative characters, 41 traits related to fruit and amount of resveratrol in 15 parts of plant was done according to grape descriptor and related methods. according to the results some traits such as spikelet weight, berry color, length of peduncle, length of berry tail, weight and len...

The present investigation aims to the isolation of Streptomycetes from saline soil. The isolates were varied in color to aerial vegetative mycelia, morphology of conidospore surface, melanin production, utilization of carbon; nitrogen source and fatty acid analysis, as well as physical and chemical characters for their habitat soil. Streptomycetes isolates exhibiting wide range of variability. ...

Populations of oak cork (Quercus suber L.) originated from different areas in Tunisia were analysed based on morphological characters to assess the overall degree of phenotypic variability, to detect similarities between the genotypes and to evaluate significant forest features. One-way ANOVA analysis shows a significant difference between oak cork populations and demonstrates that parameters m...

Genotypic or phenotypic markers for characterization of natural populations of marine microalgae have typically addressed questions regarding differentiation among populations, usually with reference to a single or few clonal isolates. Based upon a large number of contemporaneous isolates from the same geographical population of the toxigenic species Alexandrium tamarense from the North Sea, we...
