Leaf size and shape play important roles in agronomic traits, such as yield, quality and stress responses. Wide variations in leaf morphological traits exist in cultivated varieties of many plant species. By now, the genetics of leaf shape and size have not been characterized in Brassica napus. In this study, a population of 172 recombinant inbred lines (RILs) was used for quantitative trait lo...

this study was carried out to investigate flower yield and yield components in iranian rosa damascena using 20 genotypes, collected from different regions of iran and grown in drylands and deserts research station of kashan, iran, using a randomized complete block design with three replications in 2007-2008. flower yield per plant, number of flowers per plant, plant height, leaf length, width, ...

chemical and morphological characterization of different parts of banana plant(musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in orderto assess their potentiality for chemical pulp. each portion was tested forextractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosancontents as well as their fiber length and width. these segmented parts werecharacter...

in order to evaluate genetic diversity among squash landraces from northwest iran by morphological and physiological traits, 18 squash landraces belong to pumpkin, ornamental and confectionary groups were planted in completely randomized block design with three replications in agricultural research center of urmia in 2013. morphological characteristics related of fruit, seed, leave and flower a...

The ability to generate physiologically synchronous groups of insects is vital to the performance of investigations designed to test insect responses to intrinsic and extrinsic stimuli. During a given instar, the silverleaf whitefly, Bemisia argentifolii, increase in depth but not in length or width. A staging system to identify physiologically synchronous 4th instar and pharate adult silverlea...

Genetic variability, correlation and path coefficients for fifteen agro-morphological traits were studied on 100 oat lines including two checks. Genotypic phenotypic of variation high leaf number per tiller weight panicle. Traits such as plant, tiller, panicle, stem width, individual plant yield, length internode thousand seed showed heritability accompanied by genetic advance indicating that t...

background & aim: achillea filipendulina is one of the most important species of the family asteraceae and, it considered as one of the most valuable medicinal and ornamental plants. environmental factors affected on quality and quantity of the essential oil of medicinal and aromatic plants. so, selecting of appropriate season for harvesting can lead to increase quality and quantity yield. ...

background & aim: kelussia odoratissima mozaff. (apiaceae) is one of the medicinal plants and endemic in zagros mountains, iran, which unfortunately due to illegal harvest is endangered. in order to break dormancy and to evaluation of effect of different treatments on traits a factorial experiment base on completely randomized design was created on the seed zone sar-aghaseyed functions in c...
