For genetic analysis of mechanisms of leaf morphogenesis, we chose Arabidopsis thaliana (L.) Heynh. as a model for leaf development in dicotyledonous plants. Leaves of the angustifolia mutant were the same length as but narrower and thicker than wild-type leaves. The total number of cells in leaf blades of angustifolia plants was the same as in the wild type. At the cellular level in the angust...

African yam bean (Sphenostylis stenocarpa) is an underexploited legume with the potential of becoming an alternative food staple to alleviate the problem of food security. An assessment was carried out on the growth and yield of AYB affected by Telfairia mosaic virus (TeMV) Infection. Telfairia mosaic virus caused severe mosaic, leaf distortion and malformation on AYB. Analyses of results revea...

to evaluate the effect of environment on the general and specific combining ability of virginia tobacco genotypes, five varieties were intercrossed in combination in 2007 in a half – diallel design. in 2008, the ten f1 population and the five parental lines were sown in two different conditions (drought stress and non-stress) using a complete randomized block design with three replications and ...

The field experiment was conducted with twenty brinjal varieties/lines during October 2007 to May 2008 to identify shoot and leaf characteristics of brinjal plants for their susceptibility/resistance against brinjal shoot and fruit borer infestation. Borer infestation was influenced by different characters of plant shoot and leaf. Various parameters like plant height, stem diameter, number of b...

in order to study morphological variation within seeds and seedlings of a pistachio population of ‘badami-riz-e-zarand’, 20 quantitative traits were measured in sixty-seven nut and seedlings originated from them. results showed that there was positive and significant correlation between traits of nuts (seeds) and kernels, not between seedling height and crown diameter. according to measured par...

This research was carried out for evaluating phenotypic diversity and traits correlation in 60 almond genotypes and cultivars in nursery conditions. After preparation land and the bitter seeds of Shahroud22 genotype as seedling rootstocks planted in the autumn 2005. After the seed germination in the spring of the next year, the results of recorded data in 3rd may of 2006 showed that the planted...

evaluation of morphological variations in 70 genotypes of seven accessions of thymus caramanicus jalas.growing in central iran was carried out, for determining valuable characters for future breeding programs and medicinal purposes. in this study 30 quantitative and qualitative characters were evaluated. the results revealed great variabilities of important traits among populations. results of ...
