In order to investigate the morphometric diversity of Moringa populations in ten regions and villages located in Fennuj and Nikshahr of Baluchestan including Bennet, Keshgh, Desc, Madhadi, Nesfaran, Condaran, Tang Fnvjh mouth, and Haft Dokhtaran, Moringa seeds were collected. Twenty Sterile seeds of each genotype were cultured in separate petri diches in three replicates and the culture plates ...

Considering the crucial focus on plant developments as high yielding, protein, and disease-resistant varieties, in this study, the genetic diversity and nutritional traits of available kidney bean germplasms found in Bangladesh have been evaluated based on seventeen quantitative and six nutritional traits. Analysis of genotypic, phenotypic variance and covariance showed that higher environmenta...

1. Numerous plant traits are known to influence aspects of individual performance, including rates of carbon uptake, tissue turnover, mortality and fecundity. These traits are bound to influence emergent properties of vegetation because quantities such as leaf-area cover, average height, primary productivity and density of standing biomass result from the collective behaviour of individuals. Ye...

A pot experiment was designed to investigate the effects of full, above and below ground interactions of wheat with wild oat on leaf characteristics and root to shoot ratio. This experiment was conducted as a factorial based on randomized complete design with four replications. The treatments included four interference levels (above ground, below ground, above and below ground and check wheat a...

background and objectives: early watergrass (echinochloa oryzoides) is considered as a new-introduced species and then as a potential invader. investigation of competitive traits of this species, in comparison with barnyardgrass (e. crus-galli), one of the most important weeds in rice fields of guilan province, would be useful to determine its spreading possibility as an aggressive weed. theref...

Common reed (Phragmites australis (Cav.) Trin. ex Steud.) is distributed widely throughout the world with various ecotypes. This research compares the functional traits and biomass allocation patterns of two contrasting reed ecotypes. Twelve pairs of aquatic and terrestrial reed samples were collected in northern China. Significant differences in functional traits between the two reed ecotypes ...

Global vegetation models use conceived relationships between functional traits to simulate ecosystem responses to environmental change. In this context, the concept of the leaf economics spectrum (LES) suggests coordinated leaf trait variation, and separates species which invest resources into short-lived leaves with a high expected energy return rate from species with longer-lived leaves and s...
