Evaluation of lentil genotypes is important to choose selection criteria for improvement seed yield. This investigation was conducted at El-Mataana, Agricultural Research Station, Luxor governorate, ARC, Egypt assess the genotypic variability, correlation and path analysis some genotypes. Twenty-two including one as check variety (Giza 9) were tested in a Randomized Complete Block Design (RCBD)...

This experiment was conducted, to study the effect of planting time and planting density on savory (Satureja sahendica Bornm.) in 2012 in Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was carried out in split plot in time in the form of a randomized complete block design with three replicates. The main plots were planting times in two levels ...

Genetic variation for fitness-relevant traits may be maintained in natural populations by fitness differences that depend on environmental conditions. For herbivores, plant quality and variation in chemical plant defences can maintain genetic variation in performance. Apart from plant secondary compounds, symbiosis between plants and endosymbiotic fungi (endophytes) can produce herbivore-toxic ...

Ludab region, known for its unique landscape comprising a vast fertile plain surrounded by high mountains and covered by loose oak forests, is a part of Boyer-Ahmad County in southern Zagros mountain range (West Iran) with an area of 87,715 km2 located 110 km north-west of the capital city, Yasuj. The aim of this research is to assess floristic elements, life forms, chorology, and en...

The National Longitudinal Study of Adolescent Health data were used to test predictions from life history theory. We hypothesized that (1) in young adulthood an emerging life history strategy would exist as a common factor underlying many life history traits (e.g., health, relationship stability, economic success), (2) both environmental harshness and unpredictability would account for unique v...

Knowledge of leaf chemistry, physiology, and life span is essential for global vegetation modeling, but such data are scarce or lacking for some regions, especially in developing countries. Here we use data from 2021 species at 175 sites around the world from the GLOPNET compilation to show that key physiological traits that are difficult to measure (such as photosynthetic capacity) can be pred...

Floristic studies are fundamental for the applied sciences such as rangelandmanagement and conservation. Unique ecological and climatic conditions in the NorthernKhorasan Province (NKP) make it a remarkable habitat for the floristic studies. Plant specieswere collected from 50 field sites, representing major habitats of winter and rural rangelands.Surveys were conducted during active growth per...

Significant progress has been made in understanding biological invasions recently, and one of the key findings is that the determinants of naturalization and invasion success vary from group to group. Here, we explore this variation for one of the largest plant families in the world, the Araceae. This group provides an excellent opportunity for identifying determinants of invasiveness in herbac...

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...
