Trait-based approaches are widely used in community ecology and invasion biology to unravel underlying mechanisms of vegetation dynamics. Although fundamental trade-offs between specific traits and invasibility are well described among terrestrial plants, little is known about their role and function in aquatic plant species. In this study, we examine the functional differences of aquatic alien...

to evaluate morphological markers linked with drought stress resistance for screening almond genotypes in the breeding programs the effect of drought stress was studied on six nominated almond genotypes seedlings. the six pre-selected water stress mimposed almond genotypes included: homozygote sweet (butte from university of california), heterozygote sweet (shahrood12, shahrood18, shahrood21 an...

Field experiment was conducted in Karbala province during the spring season of 2018-2019. The arranged as split plot within RCBD with three replications. Urea- phosphate (UP) applied at 0, 1 and 2ml L-1 cytokines 0.5 ml L-1sprayed on two cultivars corn namely: Baghdad fager. Results revealed that cultivar superior giving highest values all studied traits lie, plant light, leaves no, leaf area, ...

Hawaiian endemic tree Acacia koa is a model for heteroblasty with bipinnately compound leaves and phyllodes. Previous studies suggested three hypotheses for their functional differentiation: an advantage of leaves for early growth or shade tolerance, and an advantage of phyllodes for drought tolerance. We tested the ability of these hypotheses to explain differences between leaf types for potte...

Plant traits are the key factors that determine herbivore foraging selection. The traits serving as defense traits against herbivores represent a wide range of traits, such as chemical, physiological, morphological and life-history traits. While many studies considered plant defense traits at the within-species scale, much less is known from comparisons of a wide range of closely related specie...
