Abstract. Information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. Vetiver grass (Vetiveria zizanioides) is a non-native perennial grass that was introduced to the Iran in 2008. This plant is a multi use species that could be considered from different viewpoints. Thus, it...

Local persistence of plant species in the face of climate change is largely mediated by genetic adaptation and phenotypic plasticity. In species with a wide altitudinal range, population responses to global warming are likely to differ at contrasting elevations. In controlled climate chambers, we investigated the responses of low and high elevation populations (1200 and 1800 m a.s.l.) of three ...

Within the last years a lot of effort has been made to improve irrigation efficiency and early drought stress detection by using various remote sensing techniques. In the present study two different species of wheat (Triticum aestivum and Triticum durum), cultivated in a growth chamber, were used to investigate the effects of drought occurring at different phenological stages. Plant physiologic...

Cereal-legume intercropping can increase yields, reduce fertilizer input and improve soil quality compared with pure culture. Designing systems requires the integration of plant species trait selection choice crop configuration management. Crop growth models facilitate understanding prediction interactions between traits, However, currently no existing model has been calibrated tested for cerea...

     Improved drought-tolerant maize hybrids would significantly reduce water consumption and increase yield in arid environments. Our knowledge about genetic parameters is very essential before starting a successful breeding program. The present research was carried out throughout three successive years between 2013-15 to reveal the pattern of inheritance in yield, yield-components and related...

in order to study the variation of fatty acids and protein content of soybean seeds and correlated morphological and phenological traits by canonical correlation analysis, 25 genotypes were evaluated with latis square design in baieakola agricultural research station of mazandaran agricultural research center in 2001. a number of 20 agronomic and eight quality traits were measured. the variatio...

The Haun, Feekes, and Zadoks-ChanpKonzak developmental stage scales are often used to report phenological information for wheat (Triticum aestivum L.) development. Agronomists familiar with one of these scales may have only a passing acquaintance with developmental scales other than the one they consider most appropriate for their purposes. This makes review and interpretation of the literature...

BACKGROUND AND AIMS Variation in fitness depends on corresponding variation in multiple traits which have both genetically controlled and plastic components. These traits are subjected to varying degrees of local adaptation in specific populations and, consequently, are genetically controlled to different extents. In this study it is hypothesized that modulation of different traits would have c...
