Cymbidium faberi is a traditional orchid flower in China that is highly appreciated for its fragrant aroma from its zygomorphic flowers. One bottleneck of the commercial production of C. faberi is the long vegetative growth phase of the orchid and the difficulty of the regulation of its flowering time. Moreover, its flower size, shape and color are often targeting traits for orchid breeders. Un...

in order to investigate the effect of concentration, time and consumption instruction of seaweed on some morphological characteristics of root and shoots of safflower, the present experiment in factorial form in a completely randomized design with three replications in research greenhouse of agriculture faculty, ferdowsi university of mashhad was conducted in 2014-15. factors examined included ...

Chemical defense is assumed to be costly and therefore algae should allocate defense investments in a way to reduce costs and optimize their overall Wtness. Thus, lifetime expectation of particular tissues and their contribution to the Wtness of the alga may aVect defense allocation. Two brown algae common to the SE PaciWc coasts, Lessonia nigrescens Bory and Macrocystis integrifolia Bory, feat...

selection and introduction of superior genotypes from native populations is one of the most common improving methods for fruit trees in the world. iran as a very important origin of apricot has a huge diversity of varieties, so a rich collection of local and imported genotypes of apricot was induced in sahand horticultural research station from 1971. nasiri 90 and other four superior varieties ...

To study the genetic variability and the genetic basis of nitrogen (N) use efficiency in maize, a set of recombinant inbred lines crossed with a tester was studied at low input (N-) and high input (N+) for grain yield and its components, grain protein content, and post-anthesis nitrogen uptake and remobilization. Other physiological traits, such as nitrate content, nitrate reductase, glutamine ...

Present addresses John N. Ferguson, Institute for Genomic Biology, University of Illinois at UrbanaChampaign, Urbana, IL, USA. Matt Humphry, British American Tobacco, Cambridge Science Park, Cambridge, UK. Abstract The ability of plants to acquire and use water is critical in determining life-history traits such as growth, flowering, and allocation of biomass into reproduction. In this context,...
