Sensory and chemical analyses were performed on accessions of rocket (Eruca sativa) to determine phytochemical influences on sensory attributes. A trained panel was used to evaluate leaves, and chemical data were obtained for polyatomic ions, amino acids, sugars and organic acids. These chemical data (and data of glucosinolates, flavonols and headspace volatiles previously reported) were used i...

Across all sensory modalities, stimuli can vary along multiple dimensions. Efficient extraction of information requires sensitivity to those stimulus dimensions that provide behaviorally relevant information. To derive social information from chemosensory cues, sensory systems must embed information about the relationships between behaviorally relevant traits of individuals and the distribution...

Background: Rosemary (Rosmarinus officinalis L.) as a member of the Lamiaceae family is a valuable aromatic and medicinal plant which is cultivated in large scale in Iran. Therefore, it is necessary to determine influence of factors affecting plant growth and drug metabolite production. Objectives: This experiment was carried out to evaluate the effects of bio-stimulators compounds on growth a...

The relationships between population growth rate and the life-cycle traits contributing to it are nonlinear and variable. This has made it difficult for ecologists to consistently predict changes in population dynamics from observations on changes in life-cycle traits. We show that traits having a high sensitivity to chemical toxicants tend to have a low elasticity, meaning that changes in them...

Wood represents the defining feature of forest systems, and often the carbon in woody debris has a long residence time. Globally, coarse dead wood contains 36–72 Pg C, and understanding what controls the fate of this C is important for predicting C cycle responses to global change. The fate of a piece of wood may include one or more of the following: microbial decomposition, combustion, consump...

Communicative traits are strikingly diverse and may vary among populations of the same species. Within a population, these traits may also display seasonal variation. Chemical signals play a key role in the communication of many taxa. However, we still know far too little about chemical communication in some vertebrate groups. In lizards, only a few studies have examined interpopulational varia...

Two field experiments were carried out in order to investigate the effect of chemicalinducers [benzothiadiazole 0.9 mM l-1, oxalic acid 1.0 mM l-1, salicylic acid 0.2 mM l-1] onphysiological and technological traits as well as on yields and antioxidant enzyme activities ofbarley grown under abiotic stress (i.e. water surplus and deficit conditions). Results showed thatrelative water content, le...

Citrus fruit tree has great commercial importance with mandarin (Citrus reticulata) as the second most important citrus crop and includes a wide range of true hybrid cultivars; however, there is lack studies about characterization evaluation germplasm for Physico-chemical morphological traits. A study on varietal selection been underway at National Research Programme since 2005-06. Evaluation s...
